Geometry-Aware Graph Transforms for Light Field Compact Representation
Mira Rizkallah, Xin Su, Thomas Maugey +1
The paper addresses the problem of energy compaction of dense 4D light fields by designing geometry-aware local graph-based transforms. Local graphs are constructed on super-rays t…

Prediction and Sampling with Local Graph Transforms for Quasi-Lossless Light Field Compression
Mira Rizkallah, Thomas Maugey, Christine Guillemot
Graph-based transforms have been shown to be powerful tools in terms of image energy compaction. However, when the support increases to best capture signal dependencies, the comput…
