Efficient All-Pairs Correlation Volume Sampling for Optical Flow Estimation 事件

Efficient All-Pairs Correlation Volume Sampling for Optical Flow Estimation arXiv:2505.16942v2 Announce Type: replace Abstract: Recent optical flow estimation methods often employ local cost sampling from a dense all-pairs correlation volume. This results in quadratic computational and memory complexity in the number of pixels. Although an alternative memory-efficient implementation with on-demand cost computation exists, this is significantly slower in practice and therefore many prior methods
