Descriptive Video Degradation Assessment with Multimodal Large Language Models

We investigate descriptive video degradation assessment (VDA) for granular diagnosis beyond the interpretability limits of conventional video quality assessment (VQA). Unlike scalar mean opinion score (MOS) regression, descriptive VDA identifies spatio-temporal degradations and explains their collective perceptual impa...

Boosting Representation Learning for High-Level Semantic Information in Facial Expression Recognition

Facial expression recognition (FER) requires high-level semantic cues to interpret abstract emotions. However, existing FER approaches commonly suffer from sparse semantic descriptions and unwanted noise from redundant facial pixels. To tackle these issues, we propose a boosting representation learning framework to bui...

Geometry-Semantics Co-Regularization for Gaussian Splatting in Indoor Reconstruction.

A geometry-semantics co-regularization framework that jointly optimizes geometry and semantics within 3DGS and develops a multi-view semantic consistency supervision to regularize the semantic distributions of Gaussian primitives, ensuring cross-view consistency for Gaussians corresponding to the same semantic category...
