Abstract
A method for applying depth-dependent effects to images includes receiving a stereo image and depth related information extracted from the stereo image, and applying an effect to the stereo image according to the depth related information. The method may also include calculating surface orientation information for the stereo image to improve the depth related information extracted from the stereo image and/or facilitate the application of effects, such as scene relighting, which leverage surface orientation information. In some embodiments, the method includes fitting a curved surface to the depth related information and adjusting the depth related information and/or surface orientation information according to the curved surface. The method may also include processing the depth related information with a bilateral smoothing filter wherein coefficients for neighboring pixels are weighted according to similarity in color and similarity in depth. An apparatus and computer-readable medium corresponding to the above method are also disclosed.
