Octree-based Video Representation

Rungui Zhou, Chuanzhi Zhou, Yuk-Kit Hou وآخرون · 2026

Video models commonly use uniform grids even though visual complexity varies substantially across space and time. We introduce OctVideo, which approximates a video clip with an octree. This hierarchy recursively partitions a spatio-temporal volume into eight subvolumes, so that smooth regions remain coarse while detail …

Geometry-Preserving Blind Watermarking for Raw 3D Point Clouds

Rungui Zhou, Chuanzhi Zhou, Ruihuan Wang وآخرون · 2026

Raw 3D point clouds are a core geometric representation. Establishing their ownership is challenging because point sets are irregular, unstructured, and frequently altered by resampling and geometric preprocessing. We present a blind watermarking framework that operates directly on xyz coordinates and supports both obj …
