We present an efficient method for such a system that combines decoding and rendering processes in order to directly synthesize the novel image without having to reconstruct all the input images. Our method jointly performs disparity compensation in the decoding process and geometry estimation in the rendering process because they are essentially equivalent if the camera parameters for the input images are known. Our method keeps both encoder and decoder complexity as low as that of a conventional intracoding method while attaining better coding performance owing to the interimage decoding. We validate our method by evaluating the coding performance and the processing time for decoding and rendering in experiments. Copyright 2009 Y. Taguchi and T. Naemura.

Introduction Camera array systems can capture multiview images of a 3D scene which allow a viewer to observe the scene from arbitrary viewpoints by using image-based rendering techniques 1 2 . Such systems require efficient coding schemes owing to the large amount of data .
