Abstract
In this paper, we propose a new method for Image Based Rendering. Many studies using stereo vision techniques, which reconstruct shape of the objects, have been reported in the field of Image Based Rendering. However, these techniques cannot avoid difficulty in determining the positions of all object surfaces explicitly. Based on the thought that the problem of Image Based Rendering is estimation of the color of incident light into virtual viewpoint, our method divides the object space into voxels, and represents the probability of existence of the object as a continuous value calculated from the differences of colors projected onto input images, and directly perform rendering using the technique of Volume Rendering. Consequently, it can synthesize virtual viewpoint images without determining the surface depth explicitly by very simple algorithm.
