| Abstract Optical flow estimation is still one of the key problems in computer vision. When estimating the displacement field between two images, it is applied as soon as correspondences between pixels are needed. The choice of the transform is an important tool in optical flow estimation. So in this paper curvelet transform is proposed to estimate the optical flow. it is found that the proposed algorithm is much better than most recently previous work based on multiwavelet. This is because curvelet transform can be efficient in finding estimates along curves. | ||
