RL-ScanIQA: Reinforcement-Learned Scanpaths for Blind 360°Image Quality Assessment
Yujia Wang, Yuyan Li, Jiuming Liu +3
Blind 360°image quality assessment (IQA) aims to predict perceptual quality for panoramic images without a pristine reference. Unlike conventional planar images, 360°content in i…
Cross360: 360° Monocular Depth Estimation via Cross Projections Across Scales
Kun Huang, Fang-Lue Zhang, Neil Dodgson
360° depth estimation is a challenging research problem due to the difficulty of finding a representation that both preserves global continuity and avoids distortion in spherical…
PanoNormal: Monocular Indoor 360° Surface Normal Estimation
Kun Huang, Fanglue Zhang, Neil Dodgson
The presence of spherical distortion in equirectangular projection (ERP) images presents a persistent challenge in dense regression tasks such as surface normal estimation. Althoug…
Multi-task Geometric Estimation of Depth and Surface Normal from Monocular 360° Images
Kun Huang, Fang-Lue Zhang, Fangfang Zhang +3
Geometric estimation is required for scene understanding and analysis in panoramic 360° images. Current methods usually predict a single feature, such as depth or surface normal.…
