A depth-image-based rendering system for generating stereoscopic images is proposed. One important aspect of the proposed system is that the depth maps are pre-processed using an asymmetric filter to smoothen the sharp changes in depth at object boundaries. In addition to ameliorating the effects of blocky artifacts and other distortions contained in the depth maps, the smoothing reduces or completely removes newly exposed (disocclusion) areas where potential artifacts can arise from image warping which is needed to generate images from new viewpoints. The asymmetric nature of the filter reduces the amount of geometric distortion that might be perceived otherwise.
We present some results to show that the proposed system provides an improvement in image quality of stereoscopic virtual views while maintaining reasonably good depth quality.Generally, DIBR process consists of two steps: image warping and holefilling.We describe the goals of the ATTEST project, which started in March 2002 as part of the Information Society Technologies (IST) programme, sponsored by the European Commission. In the 2-year project, several industrial and academic partners cooperate towards a flexible, 2D-compatible and commercially feasible 3D- TV system for broadcast environments. An entire 3D-video chain will be developed. We discuss the goals for content creation, coding, transmission, display and the central role that human 3D perception research will play in optimizing the entire chain. The goals include the development of a new 3D camera, algorithms to convert existing 2D-video material into 3D, a 2D-compatible coding and transmission scheme for D video using MPEG-2/4/7, and two new autostereoscopic displays. With the combination of industrial and academic partners and the technological progress obtained from earlier 3D projects, we expect to achieve the ATTEST goal of developing the first commercially feasible European 3D-TV broadcast system.This paper presents details of a system that allows for an evolutionary introduction of depth perception into the existing 2D digital TV framework. The work is part of the European Information Society Technologies (IST) project \Advanced Three-Dimensional Television System Technologies" (ATTEST), an activity, where industries, research centers and universities have joined forces to design a backwards-compatible, ∞exible and modular broadcast 3D-TV system. At the very heart of the described new concept is the generation and distribution of a novel data representation format, which consists of monoscopic color video and associated per- pixel depth information.
From these data, one or more \virtual" views of a real-world scene can be synthesized in real-time at the receiver side (i. e. a 3D-TV set-top box) by means of so-called depth-image-based rendering (DIBR) techniques. This publication will provide: (1) a detailed description of the fundamentals of this new approach on 3D-TV; (2) a comparison with the classical approach of \stereoscopic" video; (3) a short introduction to DIBR techniques in general; (4) the development of a speciflc DIBR algorithm that can be used for the e-cient generation of high-quality \virtual" stereoscopic views; (5) a number of implementation details that are speciflc to the current state of the development; (6) research on the backwards-compatible compression and transmission of 3D imagery using state-of-the-art MPEG (Moving Pictures Expert Group) tools.
