Abstract
Multi-resolution optical flow is the main trends of the current optical flow calculation. Wavelet transform and Gaussian filter are widely used to build multi-resolution structure of the image. In this paper, LK optical flow method mixed with pyramid was used to study the optical flow field. The different effects of wavelet transform and Gaussian filter in the flow distribution was also discussed. Experimental results show that the selected image decomposition method has a significant role in optical flow field calculation.
