| Abstract(in English) | A method for interactive rendering of photorealistic images is a fundamental technology in the field of virtual reality. This paper proposes a method for focus measurement from light fields using ATI RADEON 9800 Pro GPU as a fast processing unit for image processing and image-based rendering. It is confirmed that the proposed method enables interactive all in-focus rendering from light fields because a GPU implementation can eliminate the latency for data transmission between video memory and system memory. Experimental results show that the GPU implementation is about 7.7 times faster than a CPU implementation using Intel Pentium 4 3.06 GHz. |
