Abstract
An image processing system and method for determining a set of surface normals of one or more objects for use in rendering the object(s) is described. One or more input images are received, each representing a view of the object(s). A depth image is received representing depth values of the object(s). Coarse surface normal estimates are determined based on depth values of the received depth image. The set of surface normals are determined by applying bilateral filtering to the coarse surface normal estimates. The bilateral filtering uses bilateral filtering guidance terms based on luminance values derived from the input image, wherein the determined set of surface normals are for use in rendering the object(s).
