Abstract: Depth/disparity information is conducive to various post-production processes, such as compositing, editing, and alternate view rendering. Therefore, this paper describes a display-agnostic framework for representing depth and disparity in post-production. The paper details the requirements and constraints associated with the representation. It also shows the manner in which the interchange framework can be used during compositing, conforming, and editing. The framework simplifies the exchange of depth/disparity information gathered from live and computer-generated imagery (CGI) sources. Finally, the paper analyzes the robustness of the representation to depth/disparity conversion errors and provides example scenarios in which the representation can be used.

bio
Peshala Pahalawatta received M.Sc. and Ph.D. degrees in electrical engineering from Northwestern University in Evanston, IL, in 2003 and 2007, respectively. While there, he was a member of the Image and Video Processing Laboratory, headed by Prof. Aggelos K. Katsaggelos. In 2007, Pahalawatta joined the video compression research team at Dolby Laboratories in Burbank, CA, where he worked on video coding, quality evaluation, and the standardization of 3D video coding technology. In 2012, he joined Dynamic Digital Depth (DDD) in Los Angeles, CA, as a senior research engineer in image technology. His interests lie in image and video compression and enhancement, 3D video processing, and subjective and objective video quality evaluation.
