- Welcome to the OpenCV Basics series. In this series, we'll be going through all the basics of OpenCV from the ground up.
In this video you'll learn how to:
1. Apply Canny Edge Detection to Images
2. Tweak and Tune Detection Parameters to improve Results
3. Export final detections

P.s. Let me know how you go and drop a comment if you need a hand! - Věda a technologie
As always, clear and systematic. Thank you.
This guy is simply amazing! Love every video, super clear and inspiring, love it
Hey! As a deaf person, I greatly depend on captions - for most of your videos, they are on (I lipread and catch the occasional errors like 'captcha' when you said 'capture' - this can be prevented if you transcribe and feed your own captions... CZcams has this tool), but this one says captions are unavailable. Please continue to keep your videos accessible - I have viewed many and they have been extremely helpful on my path!! Many thanks for your hard work!
Ha, weird, it's not on for this one. Let me go check! My bad man!
@@NicholasRenotte still not on, very hard to follow to not native speakers
This was great! Thanks!
Thank you for another great video Nicholas! I am excited about the GAN can u do the toturial that in the next video
Waiting for your next tutorial on this with ANPR collectively
Thank You
🙏🙏🏽🙏🏽 from INDIA
Omg I am In love with your videos
Thank you sir for Again you effort for us
Awesome tutorial! Can we expect video/tutorial in future about Change Detection (DL) for images in (almost) same place but different time? So interesting to hear your opinion about best techniques to achieve it!
Hmmm haven't even considered this type of model before! Got an example for me?
@@NicholasRenotte for example i get plenty images everyday from same places (UAV images). I need observe some objects and detect is there any changes on that object comparing image from yesterday and if it is, make corresponding output . For example i observe all trash containers in the city every day and i need to detect changes of trash containers (maybe today the container is full and trashes are placed on top or side , so i need to detect that and make corresponding output ). I don't know if my example is clear to understand, let me know.
so for educational purpose maybe you can compare any two images (street view images), but video would be more concentrate about choosing technique and how to achieve goal
Brother! You are awesome!
Very Nice Tutorial! Found you a minute ago. Which IDE are you using in this Video ?
Hi @Nicholas Renotte I have seen all your tutorial of the Deep Reinforce Learning. Can you make a tutorial for GNN because your tutorial is way too clear to understand than my professor
Hello Nicholas,
How to crop multiple bounding box of a image using openCV ? All bounding box should be same size.
Thank you very much, I was working on something similar, processing, whether they were handwritten or non-homogeneous numbers. You would cut the image and you would use a dataset like MNIST to train a vanilla CNN or you would use transfering learning with resnet or YOLO, I don't know if those networks detect letters or numbers. sorry for my english, i'm practicing!
I found another of your video which is what I need "Automatic Number Plate Recognition"
@Nicholas Renotte how can I apply cnny Edge algorithm on multiple (2,000) images at a time? Thank you
Dude, can you get yourself a jetson-nano and do some tutorials using it? Love your channel btw, great stuff
Heyy! Thanks so much, on the list. Will probs get to it in the new year. Some sweet crypto stuff on your channel!
2 new Jetsons released just a few days ago I believe, was sent to developer account, and one was a SoM so I would assume similar to the NX version’s and therefore preloaded with a Debian/Ubuntu stack or at the very least can be flashed in a few minutes. But they been updating there Catalog a lot and have a ton of great tutorials available
could you create a gui with sliders to adjust the blur / threshold values and then click export once you've got an image you are happy with?
This was great
Helped actually the images are coming out and she shapes are but how then can I take out the shapes I like
Take a look at this: learnopencv.com/contour-detection-using-opencv-python-c/
Hi,can u plz share the code detect an object from the real image
Can you create a video on how to chat with a 3d object, but users can only respond with a line of multiple choice of emojis, the choice of emojis selected by users determine the kind of questions they get next.
sir can we do a image to text using ESP32, OpenCV and python
On a Raspberry Pi it's kinda tricky, could probably do it with a nano!
Yes please
it says cv2 module not found
Do a Q & A session or Video Please
Like as in everyone gets to post questions and I answer them? Or like a Q&A model?
@@NicholasRenotte Yeah, like everybody gets to post a question.
Thanks a lot!
Great video, but the bike is from Letonia
Great for game bot’s also, cheat away;)
fr, fr, would probs need a bit more to build out a bot with just edge detection tbh though?
Thank you for another great video Nicholas! Can I directly contact you someway please, I tried instagram and facebook but you didn't respond. Your help would mean a lot.
I'm here now! Wassup?! :)
@@NicholasRenotte I need to make a basketball ai that is focused on your shooting. Similar to your deadlift bot in someways. It will find the rim and detect the ball (when you shoot the system should leave marks on the path of the ball). After everything the ai will help you improve your shot percentage by the data you give it to it (makes and the shots that don’t go in) and the information it will collect from you (like the position of your feet the angle of your arm etc). I also want to add data from well known great shooters so the users can compare their shots with them. What do you think about it? How can I make this project?
Woah! Awesome project. Sounds like a lot of moving parts though! I would first up focusing on using OD or something similar to find the rim. Then you could estimate the position of the person (perhaps with GPS) then maybe pose estimation to calc shooting angle?
Hello Nicholas I would like some advice regarding a project I am working on. The idea is that there is a camera in a company that films the employee when he enters, matches him with the saved database, and sends the information to the backend to record attendance and other information. I want to know what I need to deal with the camera issue and matching Do I need yolo or face_recognition
@NicholasRenotte
why resizing is not working
@Nicholas Renotte ,
I hope this helps me out with my project. NIC , can I have your email or direct way of contacting you please? i need help badly for Ellipse detection
Ya shoot, what's up?! :)
@@NicholasRenotte I have an object which I want to segment from a frame but it in close to a circle but actually an ellipse in shape. the object varies in diameter(each frame having object of varying diameter some with the same ) but all have similar circular(Not perfectly circular ) shape. I want to be able to isolate it from frame. after detecting the edges. How do I go about that. I swear this is all I need to graduate I have been here 3 years now .... sometimes I feel so demoralized but your videos have somehow been very helpful
Could take a look at image segmentation if it's a specific type of object! I had a friend do it for tea leaves.
