OpenCV Error Assertion failed size width 0 size height 0

Question

I make one python program that stream my video using cv2 module. But sometimes it gives me the below error.

OpenCV Error: Assertion failed (size.width>0 && size.height>0)

How can I solve this error?

Hi@akhtar,

You are getting this error, because your camera is not able to detect any face. It means when your program unable to find any face it throws an error because of null value.

To avoid this error, you can use if else condition in your python code. If it is not able to detect any face it will pass otherwise it will run your code.

Hope this will give you some idea how to avoid this error.
