Virtual Walk-Through of Dunhuang Panorama-Based on Web

Abstract

In order to provide virtual Dunhuang panorama browse (walk-through) on the web, we propose a hybrid technique which combines both remote image rendering and image compression transportation technique. In our approach, the server renders a partial panoramic view, which is based on the users viewpoint and last movements or sends image. The server then compress images, and streams the images to the client device, which will progressively build the panoramic representation of the scene. Furthermore, in order to enhance streaming performance and quality of the interaction, we propose to use a prediction of the users movements as well as a rate control mechanism within the virtual mural. In this paper we discuss our scheme for web-based remote rendering and streaming of progressive panoramas. Our results indicate clearly that the proposed solution is able to achieve stable frame rates and throughput in general network environment.
