Congratulations teacher!
👨🏫
Thank you! So glad you enjoy the content! 😃🙌
Could you tell me the installation process
great tutorial on how to organize the project into separate steps!
Good organization is the key to a successful project I am happy you enjoyed the video! 😄🙌
srsly like the best video, now i can train my custom hand gestures etc. even, thank youu❤❤
Sir!! You have my respect I have really learned lots of things in your whole video . Just keep making this ML/DL Project videos , that you have done like implementing from scratch any exciting ML/DL project.
Just Keep Going Sir!!!
Thankyou So much!!✨✨✨✨✨✨❤❤❤❤❤❤
Thank you for your support! 😃🙌💪
Thank you so much, sir for this wonderful project. I've completed my term project easily with the help of your video. Loved how we can create our own data instead of getting it from somewhere else.
Can u pls help me out? Please
very awesome tutorial with brilliant idea and conceptualization. Thanks a lost Felipe!
Thank you for your support! Glad you enjoyed it! 😃🙌
Really Thank you sir. Great Project you helped me a lot to learn many things. After multiple errors solving finally i succeeded in making full project.
Glad the content is helpful! 😃🙌
i love all that, you are very clearly and simply 😍😍
Thank you! Glad you enjoyed it! 😃💪
Thanks a lot bro, I watched many videos and i wasted a lot of time and finally found your video and done my project.
You are welcome! Glad it was helpful! 😃
Please send your github link please
I got lot of error bro please please please please
hehe subscribed, tysm for this it was very helpful
For all who are getting errors like "inhomogeneous shapes" while training on big datasets take into account that the MP Hands processing not always return 42 features (sometimes it just doesn't predict the coordinates well enough).
To avoid this situations always check the length of every array. You must have the same amount of images and labels, and the labels (landmark coordinates) should have the same shapes.
Just remove the samples that doesn't return all the landmarks or doesn't work well with the Mediapipe hands solution, to ensure all the data has the same shape and to avoid these numpy errors (and bad models).
can you help me. when I trained only one gesture nothing else, but the system detects untrained gestures as the trained gesture why? any idea
can you please share the changed code
i think guys to solve this problem we had to tell the collect data script to save just frames where he could detect our hands else we will store bad models that will ends with this getting errors like "inhomogeneous shapes" , i actually try to solved this problem by not moving my hand when collecting data and making my model else you can try this code to check your images that are stored
This script will only print the paths of the images that are deleted due to no hands being detected. It won't display any image windows.

Great content, thank you so much.
You are welcome!! 😃
sir , the projects get closed if more hands are placed in the real-time video , i know that randomforest classifier uses only certain features , is there a way so that the program doesnt close if more hands are in the video
You're great, Man,, thank you for teaching us and put lots of research first to ensure Windows user can replicate the project too,,
.
let me leave a logs here for other Windows users:
1. dont forget using packages with exactly same version as mentioned in requirements_windows.txt.
2. Use numpy 1.23.3 version,, I take a sneak peek to your terminal output that give me information if you use numpy with that version,, at first my terminal installed numpy 2.0 version, but no luck, and then dowgrade it,,
3. If you succesfully Instal Cmake via terminal, but still got error when compiling, I suggest you to install it by install Visual Studio first
I've spent my first 4 hours dealing with those error before finally made it,,
Thank you sir for this video
Hi! Great tutorial thank you. I have a question: does this program have data augmentation? and did u calculate the sensibility and accuracy of the program?
hello from Nigeria
i must say thanks for this video
it was short, precise and educative
yes, i had some errors which i was able to handle due to my past knowledge on Deep Learning. And for those that had issues with the disparity in the length of the data, you can always pad to its maximum length
currently, i have a model that can identify 26 classes correctly and i will definitely increase the classes. i made each classes to have 700 images under different lighting condition
thanks for all you do.
bro can you send me the file for your project
@@ijaspr5486 like the whole file?
Could you share your GitHub link of your project?
@@e2mnaturals442 yes like github code or i give you my social media id
can you share your code? I'm having somre errors, while I try do identify the letters. Also, in your code, could you do with signs with both hands and with movements? @e2mnaturals442
thank you my teacher, great a video , i tried it myself, I did it :)
You are welcome! 😃 Glad you enjoyed it!! 🙂🙌
Thanks a lot! I really appreciate keeping this under an hour as well :)) We are trying to implement this model in Flutter to develop a mobile app. How can we create Flutter integration ?
For those who faces the error where it can't convert the 'data' values from dictionary data_dict, just make sure that in photo samples you are giving the full hand because if not, there will be inconsistent data and the lists will not have the same lenght inside the data_dict['data']. Do again the photos retrieve part and all should be fine
Thanks a lot!! How did you notice that this was the issue?
thanks a lot bro!!!
another great project
Thank you, Arif! I am happy you enjoyed it. 😃🙌
Thank you, very clear what was taught. I want to ask what if the dataset from a public video had the initial and final movements? whether the start and end frames go into training . and using deep learning?
Thanks man
Thank you so much it's helpful for me 😊
Glad to hear it is helpful! 😃🙌
size.width>0 && size.height>0 in function 'cv::imshow' error sir
life saver.
I have trained my model using only numbers' data. It is working but the problem is it is only showing the numbers 9 or 1 in the frame. Do you think it's because of unclear data or problem in the training model.
BTW great tutorial 👍
Great Video
Hello, I have watched your video and found it very informative. However, I was wondering if you could make a video for recognizing different characters for a sequence of movements, for example, the letter "J" or "Z." Thank you for your video.
I will try to. 🙌
I have just subscribed,
Currently working on a similar project, fingers crossed I'm at a right place..😂

I am getting plots for every data set size which i have taken is it fine bcs i have plt.savefig function, annotated it so that the plt for every dataset size is saved in main data directory
I have tried it with arabic Sign language,and it did not working correctly, I get one letter almost every time and it's wrong letter, any ideas that can help me train the model. I got the dataset from kaggle.
Really great video tutorial! Why did you choose scikt learn and not Yolo? How many changes would you have to make to use Yolo?
Do you mean using Yolo for object detection instead of mediapipe + Scikit learn? It can be done. You just need to train it. I did it with mediapipe + Scikit learn only for simplicity, and I think it also results in a more robust classifier. 🙌
great tutorial so helpful for my pfe project i actually have to do hand recognition identification biometric only but the hand contour you explained so well the part "this is the most important thing" and I really need help when it comes to the approach of how i can solve this if it? is possible for you to help me by doing a video of it ?cause its the first time for me working with python i usually work with Matlab. thank you again for this video
Hey Hayat, I am glad you found it helpful! 😄 Do you mean making a video about how to be strategic when starting a project and choose the most promising approach? Sure, I can do a video about problem solving strategies! 😃🙌
Do you have file word report ?
Thanks for your good tutorial
How to act for the rest of the letters?
thanks
The camera crashes when I show more than one hand. Can you tell me how it can be fixed?
why do you use and random forest classifier algorithm?
maybe it is better for it?
could i try with a pretrained model to get better results?
No particular reason why I used a Random Forest, I think pretty much any other classifier would have a similar performance in this case.
@@ComputerVisionEngineer Thanks felipe!!
Some hand sign have two hand ,than what we can do that situation ?
Thank you for the video, can you also make a video on sign language recognition on a video dataset (Word level american sign language dataset).
You are welcome! I will try to make a video about it. 🙌
hello Sir, I follow your video for learning about computer vision .
So I have a trouble with "DATA_DIR = './data'" , Is this file need to import from somewhere or should we need to prepare them? Can you help me to solve this?
am also thinking the same. The images seem no to be there
I am new to AI. I just want to know are we using Natural Language, Machine Learning and computer vision.
Hii!! I loved your video. I learned a lot. I just have one question, if at the end I want to form a sentence and print it, how can I save each character on the screen to have a full sentence at the end?
Hi, did you get it?
Hi, while going through this code i'm getting model_dict = pickle.load(open('./model.p', 'rb'))
FileNotFoundError: [Errno 2] No such file or directory: './model.p' and I didn't find any model.p file in your repository
Hey, you can create the model yourself following the steps I describe in the video. 😃🙌
can we make this project with pose detection models like openpose or deeppose? and what is the difference
Hola from India sir, Sir i enjoyed your video very much. sir, I have a small doubt can you tell me how to check and the accuracy of the model being trained.
Great video but How do you do the collecting images part of the code?
hey its does not work for more than 5 sign can show value error about the shape can you please fix it
Can the project created by exported to an .exe? Im worried because of the pickle file.
why does it close when you put another hand?
Who can I add more sign because it's getting error when I try to add more signs
Just wanted to tell you that your project is very famous in SMIT 😊
😃 That is soooo cool! I am happy to help you guys. 😊🙌
Have you manage to Train the model with all alphabet letters
Hlo Sir, very nice video.... I also want to make a similar project ... But there will a bit difference.. I want to generate the entire subtitle for people who can't speak using their hand gestures during video conferencing in real time.
Can you please guide me with the same ... Bcoz I completely a beginner. Your help will be appreciated. Thanks in advance. 😀
Hey Sourabh, it sounds like a complex and very cool project! I would start by saving all the symbols you detect, its confidence score, and the duration of time you detect them so you can analyze this info later on. This is going to help you to understand the problem a little better and also it is going to help you to define rules in order to achieve your goal. 😃💪
Hi Sourabh were you able to make it if yes could you please share some update or code for the same
The app crashes when using both hands. How can I fix this?
I checked the github repo and there are some changes compared to the video. Why are you substracting the min of x_ from x (data_aux.append(x - min(x_))), also for y ? Why is it necessary to do that instead of just append x the way it is to the array. I saw u did that in the data processing and also in the model testing. Thanks a lot!
Hey George! Yeah, I sent that change in a new commit. It makes the solution more robust, you could think about it as a way of 'normalization'. This makes the classifier learn better than the (x, y) position of each landmark is not that important, the distance of each landmark to each other landmark is what matters most! 😃💪
@@ComputerVisionEngineer Thanks a lot for the answer! I thought it has something to do with the mediapipe library and is a must, but it actually makes sense to be some kind of normalization. Thanks for you time!
hi I am a 15 year old and i want to do this for my school tech convention. What program are you using to code this
Hello, i was adding new alphabets to the dataset and got this error , unable to solve : " File "D:\Major project\.Major Project\code\train_classifier.py", line 11, in

Cant we get any tflite file from this model ?
how to make this project on web based like on react or flask
Hi sir,
Thanks for your tutorial.
Yet, I a problem in locating the file(./data), and received an error message of [Errno 20] Not a directory: './data/.DS_Store'. while using "create_dataset.py". Currently all file are put in desktop, do you know why? (I m using MacBook)
The thing about Apple is that MacOS often puts a file called ".DS_Store" in the directory which stores some information. In your code where you iterate over folders, compare the name with ".DS_Store" and simply skip it
Hello , great tutorial 😀can this same approach be applied for british sign language because that uses both hands to make gestures , also can this be deployed in the real world and used at production level ?
You would need to make some edits in order to use it with both hands but I guess it would work, yes. Regarding the performance, yeah you could train it and improve it so it can be used at a production level. 🙌
thanks @@ComputerVisionEngineer 😁i'll try and see if it works out
Hey @@ComputerVisionEngineer , its not working efficiently for the british sign lang , maybe because it uses both hands , do you have any suggestions on how i can build up my project , it'll be a huge help , thanks
Hello sir, I got a one problem. I made the same with you and my code is worked but it only showed at least 5 mins for capturing then the camera will shutdown automatically and got some errors. :((((
can i ask how can you moved this into mobile / android studio
Is there a way that we can contact you apart, from the comments section, because I really need your help on the splitting of the datasets, I have followed every step in the tutorial but to no avail, it it not working for me....
The part were you are splitting the data to training set and test set, to be specific
You may try to contact me in our discord.
How can I get accuracy for the letters predicted?
Basically I want live accuracy for the letters that are predicted , since if you show any random hand gesture it will always predict some random letter, so it will be much better if you could also show live accuracy .Is it possible can u guide me a little bit through this?
Try using the method 'predict_proba' instead of 'predict'. You wil get a probability vector for all the classes. Taking the largest number will give you the confidence value you are looking for. 💪💪

Hello, I have watched your video and found it very informative. However, I was wondering what is the limitation of this project?
Hey, limitation in terms of possible symbols? I would say any static symbol made with only one hand.
How will this accept video feed from a phone ?
great project! may i ask what algorithm is used in your sign language?
Hey, thank you! I am using mediapipe as a hand detector and landmark detector and a Random Forest classifier as sign classifier. 🙌
does it only recognise A B and L? or all the other letter?
@ComputerVisionEngineer ValueError: X has 84 features, but RandomForestClassifier is expecting 42 features as input..I am getting this error when i run the inference_clasifier.py model...What change should i make in the code.....
If you're getting this, that means you're showing something else that isn't in the data. Only show what you've captured. Or else simply increase number of classes and take different pictures from different angles.

Great tutorial! Can you tell me how can I do this for Indian Sign Language which uses 2 hands?
I am looking at the Indian sign language alphabet and I see some characters are done with 2 hands and others with 1 hand. In order to do something based on landmarks as we did on this video you would have to train 2 classifiers, one of them taking as input the landmarks of one hand only (as we did on the video) and the other classifier taking as input the landmarks of both hands. Then some logic to apply one classifier or the other one depending on how many hands appear on the frame. Or, you can just follow a different approach and train an image classifier taking the crop of the hand/s. 💪🙌

i think guys to solve this problem we had to tell the collect data script to save just frames where he could detect our hands else we will store bad models that will ends with this getting errors like "inhomogeneous shapes" , i actually try to solved this problem by not moving my hand when collecting data and making my model else you can try this code to check your images that are stored
This script will only print the paths of the images that are deleted due to no hands being detected. It won't display any image windows.

when you crop the image to just show the sign does that mean anyone can sign the alphabet and it will show what sign they are doing?
Once the model is trained, anyone can sign the alphabet and it will show what sign they are doing.
Hello, thank u for tutorial, that was amazing but i have an error when y run the classifier:
ValueError: X has 42 features, but RandomForestClassifier is expecting 84 features as input.
how can i fix that error?
@michaenrangelgiraldo5428 Okay so, I'm assuming that you are getting this error when predicting for that I just put an if condition like:
if (len(data_aux) != 84)
And with in that if condition I predict the values. I myself don't know whats causing this error but my assumption is it has something to do with the both left and right hand landmarks (42+42=84). Nevertheless, this solves this issue hope it will help you too.
Can you try this code:
desired_length = 4200
# Pad data_aux with zeros to achieve the desired length
while len(data_aux) < desired_length:
data_aux.extend([0.0, 0.0])
# Truncate data_aux if it exceeds the desired length
data_aux = data_aux[:desired_length]

hello sir i am getting this error
ValueError: The least populated class in y has only 1 member, which is too few. The minimum number of groups for any class cannot be less than 2.
x_train, x_test, y_train, y_test = train_test_split(data, labels, test_size=0.2, shuffle=True, stratify=labels)
i observe that if i remove stratify i donot get error but after that i get
0.0% of samples were classified correctly !
Hey, how many different symbols are you trying to classify? How did you collect the data for each symbol?
@@ComputerVisionEngineer I change number_of_classes to 5 and i collect data through opencv by capturing images(by using the method describe in this video)
Note: python version 3.11.2
total 5 symbols each got 0 to 99 images
There is a probably a bug with the data. Take a look at 'labels', how many elements are there for the different classes? Is it an array of integers or is it other data type?
@@ComputerVisionEngineer Now i am getting this error when i make 25 classes(for each alphabet).
data = np.asarray(data_dict['data'])
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (2471,) + inhomogeneous part.
EVERYTHING IS WORKING FINE, EXCEPT FOR THE FACT THAT THE MY FINAL PROGRAM IS UNABLE TO RECOGNIZE ANY SIGN. IT JUST GIVE EVERY SIGN THE SAME LABEL WHATEVER THERE IS IN THE INDEX 0 OF THE LABEL LIST. I don't understand why its not working???
same here, did you fix it?
Hello!
I tried to do exactly what you did but using the 26 alphabets. I don't know where I went wrong but the data list when converted to an nparray is giving me this error: ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (2581,) + inhomogeneous part. I have so many things but I am utterly stuck. Please do you have any idea on how I can fix this error.
Hey, not sure what could be going on, although it is always a good practice to take projects one step at the time. Try to do it with only 2 or 3 symbols and work your way up. It will make things easier to debug. 😃🙌
@@ComputerVisionEngineer Thank you. I took your advice and was able to fix the problem by breaking it down. Turns out the data for 3 letters were not properly captured but I re captured them and the 26 letters are working perfectly!! Thank you.
@@user-mh6ek3hv3k Amazing! Happy to hear you solved the problem! 😃
@@user-mh6ek3hv3k i am actually also facing the same error how can i identify which letter data is not captured correctly? pls can you tell me
@@foru1854 What I did was start with the first letter (A) , did carried out all the steps and trained the model. When I saw it worked, I added the second letter and did the two; then the third and that gave me the error so I knew the third had a problem and recaptured. I followed on like that and when I add a new one and I get the error I will know that alphabet needs to be recaptured. Hope that helps
i'm getting this error, please help
