Shape from photometric stereo images is a method of constructing 3D shape of a 2D image of any scene using its multiple images. It recovers shape from multiple images of the same scene generated using a fixed viewing direction and the different light source direction. In this work we have considered only two images- left image and right image of fracture surface of High Speed Low Alloy (HSLA) material. The images used in this paper are captured using Scanning Electron Microscopes (SEMs). We have presented a very simple approach to recover the shape form photometric stereo-images -using features matching algorithm.
