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 … WitrynaFirst, our Spatial Pyramid Network (SPyNet) is much simpler and 96% smaller than FlowNet in terms of model parameters. This makes it more efficient and appropriate …

WitrynaIn this work we review the coarse-to-fine spatial feature pyramid concept, which is used in state-of-the-art optical flow estimation networks to make exploration of the pixel flow search space computationally tractable and efficient. Within an individual pyramid level, we improve the cost volume construction process by departing from a warping- to a … WitrynaOur second contribution revises the gradient flow across pyramid levels. The typical operations performed at each pyramid level can lead to noisy, or even contradicting gradients across levels. We show and discuss how properly blocking some of these gradient components leads to improved convergence and ultimately better performance.
