Free viewpoint image reconstruction from multiple differently focused images and its implementation by CELL-based computing

Abstract

This paper deals with the CELL-based distributed processing for generating free viewpoint images by merging multiple differently focused images. We previously proposed the method of generating free viewpoint images without any depth estimation. However, it is not so easy to realize real-time image reconstruction based on our previous method. In this paper, we discuss the method to reduce the processing time by dimension reduction for image filtering and CELL-based distributed processing. Especially, the method of high-speed image reconstruction by the CELL processor on SONY PLAYSTATION3 is described in detail. We show some experimental results by using real images.
