WebHowever, the TV-L 1 optical flow method is inaccurate near edges and computationally intensive. In this paper, we proposed a technique, called Edge-based Image Decomposition (EID), to improve the accuracy in the edge areas and also accelerate the original TV-L 1 method. EID improves the performance by decomposing image into edge regions and ... Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image.

WebOptical flow is the apparent motion of brightness patterns in the image. Generally, optical flow corresponds to the motion field, but not always. For example, the motion field and optical flow of a rotating barber's pole are different, as illustrated in figure 3. WebJun 20, 2024 · The basic idea behind the unsupervised optical flow models is to warp the second image toward the first image according to the estimated optical flow. The objective is to minimize the difference between the first image and the warped “reconstructed” image, except for the occluded regions [18, 19]. Such an idea works well for non-occluded ...
