I1. second input image of the same size and the same type as prev. flow. computed flow image that has the same size as prev and type CV_32FC2. Implemented in cv::optflow::OpticalFlowPCAFlow.
Web1. I noticed that in the OpenCV_Contrib modules, there is a DISOpticalFlow algorithm which has 3 presets: Medium, Fast and UltraFast. Does anyone know what the tradeoff between speed and accuracy is between these? I understand that the parameters are set here, but is there any analysis on how these effect speed and accuracy?
