    I've reached the last part of the video but I'm left with some sort of a cliffhanger because it's incomplete and since you've shifter to a different website now, I can't access to the original code. I hope you can put the code back :) much appreciated :D

    Amazing! I have been following your tutorials and I got to learn a lot from them. There's a thing I want to implement, Realtime dynamic hand gesture recognition. I couldn't find a suitable source for that one over the internet. Although I could train your traffic signal model for getting a static solution for the same. If You could consider a dynamic project for one of your videos that'd be very helpful.

    • @averno6174
      @averno6174 Před 4 lety +1

      Hi, I'm new to Python but according to code in video attendance system you have encoded images in encodeListKnown, a list_variable containing a list of arrays (the encoded values) for each image.
      If you want to have a pre-trained file with trained images you only have to save that list after training and load it wherever you need.
      If you want to have a pre-trained file with trained images and corresponding labels, you can create a dictionary from encodeListKnown and classNames (merge both lists; value-index)
      If you want to add from code new trained images you have to:
      -get new image of detected face
      -save it to repo directory (remember the name will be the label)
      -convert into RGB
      -encode that new image
      -append that encoded to encodeListKnown and save it to file
      And there you are, you have an updated file with new recognized image if I am not wrong. Then append this encoded to dicionary getting updated classNames value if you need second approximation.
      I invite you to test coding and share your results, I am sure everybody will help you if you try and post code with your doubts
      Maybe I am making mistakes, I am new to Python you know, but I think this could be a Good solution.

      After calling the markAttendance function you can crop the main image and save the image using imwrite.
      Your croped image would be imgCropped = img[y1:y2,x1:x2] then u can save this with imwrite funciton.
