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. port mor islay https://ticohotstep.com

For the ease of representation, only a design of 3-level pyramid is shown. Given an image pair ( I 1 and 2), NetC generates two pyramids of high-level features … WitrynaWe learn to compute optical flow by combining a classical spatial-pyramid formulation with deep learning. This estimates large motions in a coarse-to-fine approach by warping one image of a pair at each pyramid level by the current flow estimate and computing an update to the flow.
