Treatment of refractory anti-melanoma differentiation-associated gene 5 anbibody-positive dermatomyositis complicated by rapidly progressing interstitial pulmonary disease: Two case reports
BACKGROUND: Anti-melanoma differentiation-associated gene 5 antibody-positive (anti-MDA5 Ab(+)) dermatomyositis complicated with rapidly progressive interstitial lung disease (anti-MDA5 Ab(+) DM-RP-ILD) has an unclear underlying mechanism with no recommended unified treatment plan. Herein, one of…

VistaGEN: Consistent Driving Video Generation with Fine-Grained Control Using Multiview Visual-Language Reasoning
Driving video generation has achieved much progress in controllability, video resolution, and length, but fails to support fine-grained object-level controllability for diverse driving videos, while preserving the spatiotemporal consistency, especially in long video generation. In this paper, we…

Learning Perceptual Representations for Gaming NR-VQA with Multi-Task FR Signals
No-reference video quality assessment (NR-VQA) for gaming videos is challenging due to limited human-rated datasets and unique content characteristics including fast motion, stylized graphics, and compression artifacts. We present MTL-VQA, a multi-task learning framework that uses full-reference…

GCRayDiffusion: Pose-Free Surface Reconstruction via Geometric Consistent Ray Diffusion
Accurate surface reconstruction from unposed images is crucial for efficient 3D object or scene creation. However, it remains challenging, particularly for the joint camera pose estimation. Previous approaches have achieved impressive pose-free surface reconstruction results in dense-view settings…
