WebKLT Optical-Flow Method 2.1.1. Assumptions of Optical-Flow Method The optical-flow method is based on two assumptions: brightness constancy and small motion; that is, the pixel value of the same points between frames are unchanged and the motion of the points is small. Figure 2 shows three target points in two adjacent images. WebBased on the optical flow, this method allows users to track points with a specific interval in the chosen region and reduces the displacement drift induced by the Kanade–Lucas–Tomasi (KLT) method. With the method applied, the region of interest is relocated according to pixel motion, and feature points are reselected. tatis sr cardinals
