        "Thephotometric stereo method is extended to four-source photometry for obtaining 3-dimensional shapes of visually textured and specular surfaces from intensity values. The table look-up approach (based on reflectance maps) for determining surface normals is shown to be of limited value in this context and a more direct method of computing these normals is used. Our method also eliminates the requirement of a preliminary system calibration procedure. The method is applied to real images as a test of its applicability."
