High-speed free viewpoint image reconstruction from 3-D multi-focus imaging sequences and its implementation by Cell-based computing

Abstract

We previously proposed the method of generating free viewpoint images without any depth estimation. The method realizes robust image reconstruction by applying a certain 3-D filter to the sequence. Then, we also proposed effective image reconstruction by integrating the 3-D sequence into a single 2-D image and applying a 2-D filter to the image. In this paper, we discuss more high-speed image reconstruction by the Cell/B.E. that is reasonable and gains high performance for media processing. We show some experimental results by using real images and we discuss the possibility of real-time free viewpoint image reconstruction.
