Insignificant shadow detection for video segmentation [PDF]

, 2005
To prevent moving cast shadows from being misunderstood as part of moving objects in change detection based video segmentation, this paper proposes a novel approach to the cast shadow detection based on the edge and region information in multiple frames.

Spectral Robustness Mixer: Cross-Scale Neck for Robust No-Reference Image Quality Assessment

Technologies
No-reference image quality assessment (NR-IQA) models achieve high correlation with human mean opinion scores (MOS) on clean benchmarks, yet recent work shows they can be highly vulnerable to small adversarial perturbations that severely degrade ranking ...
