A novel image-based rendering method by linear filtering of multiple focused images acquired by a camera array
Akihiro Kubota, Kiyoharu Aizawa · 2004
In this paper, we present a novel approach to image-based rendering (IBR) for generating an arbitrary view image with arbitrary focus for a scene consisting two approximately constant depths. The presented method differs from the conventional IBRs using multiple view images in that we acquire two differently focused images from each camera position and render parallax and focus effects on objects at different depth simply by linear filtering of the acquired images without segmentation. Experimental results on the real images acquired with 4 cameras located in parallel are presented.
