The relationship between body, forces acting upon it, and its motion. In an inertial frame of reference is when net force is equal to zero = therefore there is no resistance to the object’s velocity. First law: In an inertial frame of reference, an object either remains at rest orContinue Reading
Is a force(tension force to be exact) that makes a body follow a curved path with a center. The force’s direction is always to the instantaneous center of the path and orthogonal to the motion of the body. The body’s acceleration can be calculated as: a= v^2/r (where v squaredContinue Reading
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
