Improving optical flow on a pyramid level
WitrynaWithin an individual pyramid level, we improve the cost volume construction process by departing from a warping- to a sampling-based strategy, which avoids ghosting and … Witryna10 lip 2024 · SPyNet consists of 5 pyramid levels, and each pyramid level consists of a shallow CNN that estimates flow between a source image and a target image, which is warped by the current flow estimate (see Fig. 7.2b). This estimate is updated so that the network can residually refine optical flow through a spatial pyramid and possibly …
