The motion direction of a contour is ambiguous(usually to a combination of left/right with up/down), because the motion component parallel to the line (edge) cannot be inferred based on the visual input. You can only tell the motion locally in the direction perpendicular to the edge(line).Continue Reading

In order to compute Optical Flow there are two assumptions/constraints: Image moves in u(x cord) and v(y cord): The brightness(grayscale)/color consistency is same between the original image I ( x, y,t),  and the image in I ( x+u, y+v,t+1). The change in motion is almost zero(smooth), which means that the original IContinue Reading
