Spatial Domain Analysis on Focus Measurement for Light Field Rendering
Keita Takahashi, Takeshi Naemura (The Univ. of Tokyo)
Abstract (in Japanese) (See Japanese page) 
(in English) For synthesizing free-viewpoint images of high quality from a set of multi-view images, we proposed a
novel all in-focus rendering method by combinating light field rendering and a focus measurement algorithm. This paper introduces a detailed spatial domain analysis of the focus measurement. The advantages of this analysis are as follows: First, the application scope of the proposed method is extended to general camera-arrays that do not have tetragonal grid structure. Secondly, the relation between the proposed method and space-sweeping method is clarified. Finally, we can see some possibility for discussing the accuracy of the focus measure and the effect of occlusions on it.
