Abstract
An image processing system and method for determining an intrinsic color component of one or more objects for use in rendering the object(s) is described herein. One or more input images are received, each representing a view of the object(s), wherein values of each of the input image(s) are separable into intrinsic color estimates and corresponding shading estimates. A depth image represents depths of the object(s). Coarse intrinsic color estimates are determined using the input image(s). The intrinsic color component is determined by applying bilateral filtering to the coarse intrinsic color estimates using bilateral filtering guidance terms based on depth values derived from the depth image.
