Detailed Documentation
This implementation focuses on computing optical flow fields between adjacent frames in video or image sequences. The algorithm employs a polynomial expansion method where users need only configure the video path before execution. The optical flow calculation leverages polynomial basis functions to approximate motion vectors, typically implemented through spatial-temporal derivatives and least-squares fitting. Key functions would involve frame extraction, gradient computation, and matrix operations for solving polynomial coefficients. This ready-to-use approach provides convenient optical flow estimation with minimal configuration requirements.
