Self-Conditioned Probabilistic Learning of Video Rescaling

ICCV 2021poster

Bicubic downscaling is a prevalent technique used to reduce the video storage burden or to accelerate the downstream processing speed. However, the inverse upscaling step is non-trivial, and the downscaled video may also deteriorate the performance of downstream tasks. In this paper, we propose a se…

Self-supervised Motion Representation via Scattering Local Motion Cues

ECCV 2020poster

Motion representation is key to many computer vision problems but has never been well studied in the literature. Existing works usually rely on the optical flow estimation to assist other tasks such as action recognition, frame prediction, video segmentation, etc. In this paper, we leverage the mass…

No-reference image quality assessment for photographic images of consumer device

ICASSP 2016accepted

In this paper we study common, camera-specific kinds of distortions and propose a no-reference image quality assessment algorithm for photographic images produced by consumer devices. Those real consumer-type images, being different from simulated-distortion images, are with realistic artifacts and…
