Optical flow image
WebHowever, the TV-L 1 optical flow method is inaccurate near edges and computationally intensive. In this paper, we proposed a technique, called Edge-based Image Decomposition (EID), to improve the accuracy in the edge areas and also accelerate the original TV-L 1 method. EID improves the performance by decomposing image into edge regions and ...
