Hi there! Here is the whole codes of OpenCV course's every single lesson which is taught in Koolac Academic Group.
This course teaches you the fundamentals of Computer Vision and Image Processing basics.
Farsi
You can purchase this course from https://koolac.org/product/opencv/
After buying the course, you start to watch the course's episodes consecutively. Each video contains a code or atleast an explanation of what is going on during that specific episode. After watching an episode, if the episode includes a code, you only have to uncomment those lines and execute the program. After that, comment them again and go after the next episode codes and repeat this loop again :)
Enjoy!
