Abstract

This paper presents a novel view interpolation method for reconstructing an intermediate all-in-focus image from defocused stereo images of a scene consisting of two depths. In the presented method, the novel view can be reconstructed as a sum of the filtered stereo images. The reconstruction filters are derived as stable and linear space-invariant ones; thus the presented method does not require estimation of feature correspondence. Experimental results on real images showed that view interpolation was possible with sufficient quality.
