Analysis of compressed depth and image streaming on unreliable networks

This paper explores the issues connected to the transmission of three dimensional scenes over unreliable networks such as the wireless ones. It analyzes the effect of the loss of compressed data packets in a typical image-based rendering scenario, where a set of compressed images together with the corresponding depth maps are transmitted and used to generate the views required from the user at client side. The different impact on the rendered views of the geometry and texture packets is analyzed in detail, taking into account also the position of the lost packets and the warping operation. Finally we will discuss how to exploit this results in the design of an efficient network protocol for the transmission of 3D models.
