Abstract

Disclosed are a method and an apparatus for processing a multi-view image. The method for processing a multi-view image according to the present invention comprises the steps of: three-dimensionally warping the depth map obtained from a depth camera by the viewpoint of a multi-view camera, in order to obtain a multi-view depth map; generating a multi-view trimap, corresponding to the multi-view image obtained from the multi-view camera, using the multi-view depth map; generating a multi-view alpha matte, corresponding to the multi-view image, using the multi-view trimap; and applying the multi-view alpha matte to the multi-view image so as to extract a multi-view foreground. The present invention automatically performs high quality image-matting on a multi-view image.
