WebJun 20, 2024 · Optical flow is a per pixel prediction and the main idea is that it assumes a brightness constancy, meaning it tries to estimate how the pixels brightness moves … 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 ...
