arXiv:2505.16942v2 Announce Type: replace-cross 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 process images at downsampled resolutions, missing fine-grained details. To address this, we propose an algorithm for both memory and compute-efficient implementation of
The continuous push for more efficient and accurate AI models, especially in high-demand fields like computer vision, drives ongoing research into optimizing foundational algorithms.
Improved efficiency in optical flow estimation can enable real-time, high-resolution AI applications previously limited by computational overhead, impacting areas from robotics to autonomous systems.
This advancement suggests a path toward more practical deployment of AI models requiring dense all-pairs correlation, allowing higher resolution processing without prohibitive resource costs.
