WebJan 21, 2024 · Step 5.1 : Fix border artifacts. When we stabilize a video, we may see some black boundary artifacts. This is expected because to stabilize the video, a frame may have to shrink in size. We can mitigate the problem by scaling the video about its center by a small amount (e.g. 4%). WebDec 10, 2024 · This was remedied by the CAMShift Algorithm. Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. It is 2D vector field where each vector is a displacement vector showing the movement of points from first frame to second.
