pix_opencv_of_bm

pix_opencv_of_bm applies a block-matching optical-flow algorithm to an image stream to detect movement, marking the block with the greatest motion using a white arrow. It reports the largest movement amplitude, that block’s angle, and the average movement angle; angles are in degrees from -180 to 180, and parameters such as block size, shift size, search range, threshold, and minimum block count can be configured.
