Claim One:
1. A method, comprising: obtaining a current frame and a next frame of a video frame sequence comprising a plurality of frames, and obtaining a segmentation for the current frame, wherein the segmentation indicates a region of interest in the current frame, wherein the region of interest includes a plurality of pixels in the current frame; and generating a dynamic color flow model for the region of interest in the next frame, wherein said generating a dynamic color flow model comprises: for each pixel in the region of interest in the current frame: determining a motion vector for the pixel relative to the next frame, wherein the motion vector indicates a predicted location for the pixel in the next frame; and generating a local probability map for the pixel in the next frame, wherein the local probability map is centered at the predicted location, and wherein variance of the local probability map is determined according to magnitude of the respective motion vector; propagating colors from the pixels in the region of interest in the current frame to pixels in the next frame according to the generated local probability maps.
