BASE ANCHORED MODELS AND INFERENCE FOR THE COMPRESSION AND UPSAMPLING OF VIDEO AND MULTIVIEW IMAGERY

摘要

A method of representing displacement information between the frames of a video and/or multiview sequence, comprising the steps of assigning a plurality of the frames to a Group of Pictures (GOPs), providing a base displacement model for each GOP, the base displacement model describing a displacement field that carries each location in a designated base frame of the GOP to a corresponding location in each other the frame of the GOP, and inferring other displacement relationships between the frames of the GOP from the base displacement model. Embodiments include a piecewise smooth displacement field, deformable mesh, reverse displacement field, double mapping, synthesize optical blur and foreground-background discrimination process.
