From shape from shading to object recognition

摘要

Recognition of objects is one of the main goals of computer vision. Several ap- proaches have been proposed to solve this problem using 3-D shapes. In most of them it is assumed that the 3-D shape (depth map) is available. Several object recognition systems use range images to extract the 3-D shape. We present a method that uses a shape from shading algorithm to perform 3-D Object recognition for simple objects. This method extracts the 3-D information from A single intensity image, then segments the object into regions.
