GCRayDiffusion: Pose-Free Surface Reconstruction via Geometric Consistent Ray Diffusion

ICCV 2025poster

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,…

Regression or classification? New methods to evaluate no-reference picture and video quality models

ICASSP 2021accepted

Video and image quality assessment has long been projected as a regression problem, which requires predicting a continuous quality score given an input stimulus. However, recent efforts have shown that accurate quality score regression on real-world user-generated content (UGC) is a very challenging…
