Our method introduces a sparse global matching algorithm to effectively capture large motion in video frame interpolation, by integrating global-level information to compensate for the limitations of local-level flow estimation.
Kivonat
The content discusses a new pipeline for Video Frame Interpolation (VFI) that can effectively integrate global-level information to alleviate issues associated with large motion.
The key highlights are:
The method first estimates a pair of initial intermediate flows using a high-resolution feature map to extract local details.
It then incorporates a sparse global matching branch to compensate for flow estimation, which consists of identifying flaws in initial flows and generating sparse flow compensation with a global receptive field.
Finally, it adaptively merges the initial flow estimation with global flow compensation, yielding more accurate intermediate flows.
The method demonstrates state-of-the-art performance on the most challenging subsets of commonly used large motion benchmarks, including X-Test-L, Xiph-L, and SNU-FILM-L hard and extreme.
The authors analyze the motion magnitude and sufficiency within existing benchmarks, and curate the most challenging subsets for large motion frame interpolation evaluation. Their method is able to effectively handle these challenging large motion scenarios, outperforming previous approaches.
