Holographic Optimized Processing Engine

SPIRIT project - Retail sector

hope pipeline

Abstract

The HOPE project enhances the SPIRIT platform by advancing real-time holographic communication for retail applications, with a specific focus on real-time teleconference experiences. The project will focus on incorporating semantic, importance-driven compression, resampling, and filtering to highlight essential details, such as facial features, body movements and even points of interest. This not only optimizes bandwidth usage but also improves the overall user experience by delivering high-quality visualizations even in bandwidth-constrained environments.
