Cross-Component Residual Prediction for Geometry-Based Point Cloud Compression

ICASSP 2025accepted

Point cloud compression is pivotal for the success of immersive multimedia applications. For attribute compression in geometry-based point cloud compression (G-PCC), Region Adaptive Hierarchical Transform (RAHT) is the preferred coding method. Inspired by the significant impact of cross-component pr…

Spherical Video Coding with Geometry and Region Adaptive Transform Domain Temporal Prediction

ICASSP 2020accepted

Many virtual and augmented reality applications depend critically on efficient compression of spherical videos. Current approaches apply a projection geometry to map a spherical video onto the plane(s), wherein a standard codec can be used for compression. Video coders employ simple pixel copying fr…

A Deterministic Annealing Approach to Switched Predictor Design for Adaptive Compression Systems

ICASSP 2019accepted

Adaptive prediction is important in the compression of non-stationary signals, and a common remedy is to switch between appropriately designed prediction modes. This paper presents a near optimal procedure to design prediction modes for an adaptive compression system. The main challenges include: in…

Deterministic annealing based design of error resilient predictive compression systems

ICASSP 2017accepted

This paper considers near optimal design of predictive compression system that accounts for packet loss over unreliable networks. Major challenges to address include, propagation of errors due to packet loss through the prediction loop, mismatch between statistics used for design and during operatio…
