Compute visibility without depth in multi-reference images

One of the key problems in image-based rendering is to decide the visibility of objects in arbitrary viewplane. And reducing the need to compute depth for rendering has attracted a wide research interests. Most previous methods either work only on one reference image, which is unable to provide sufficient information for generating new views, or still rely partly on the depth information. In this paper, a novel approach is proposed to this problem based on multi-reference images, Where we deduce the warping function and a rendering order for image pixels onto the intermediary "aided-view", and in turn, to the target plane. By two-steps warping, it\´s proved a feasible method to compute visibility without depth in multi-reference images.
