WebIn this project, you will be implementing a Photometric Stereo algorithm. Photometric stereo is a method for reconstruction of the depth map (the surface) and albedo of an object from several photographs of the object in a fixed position but under different lighting conditions. Your job will be to write MATLAB functions that will be able to calibrate the … Webfor photometric calibration. Albedo texture is also generated after normal map computation. Finally, the 3D model is recon-structed by fusing the depth and normal. 3. Binocular photometric stereo: 3D face reconstruction pipeline 3.1.
