Abstract: An optical flow system includes a binary mask generation circuit and an optical flow circuit. The binary mask generation circuit is configured to receive a plurality of points of interest from a captured image that contains an array of pixels arranged as rows and columns and includes width lines that correspond to the rows and height lines that correspond to the columns. The binary mask generation circuit is also configured to generate a binary mask based on the plurality of points of interest. The binary mask includes a representation of a subset of the plurality of points of interest. The optical flow circuit is configured to receive the binary mask and generate an optical flow map of the subset of the plurality of points of interest.
