Abstract: Detecting the boundaries of deformation objects is one of of the difficulties of optical flow estimation and it is hard to solve only using improved optical flow algorithms. Gradient field optical flow estimation for color image sequences based on automatic growcut was presented. It combined the segmented information with gradient field optical flow estimation to improve the detection accuracy for deformation objects.
