Abstract
A method is executed by an electronic device in a video streaming system including a macroblock detector. The method includes receiving a video stream from a video source, selecting a frame from the video stream, detecting edges in the frame of the video stream, generating straight lines from detected edges in the frame of the video stream, identifying squares in the straight lines in the frame with polygon approximation, and outputting an indication of a detected macroblock in the image in response to identifying at least one square with characteristics of a macroblock in the frame.
