This post explains my understanding on Aperture Problem in Optical Flow and Lukas-Kanade method which is one of approaches to solve the problem. First, Optical Flow is a one way to estimate motion flow by analyzing pixel images of continous frames. Assuming Bright Constancy which leads to Gradient Constancy, one can define a line in the (u, v) space where u, v stand for dx / dt , dy / dt. But we..
