This paper presents an approach to construct 3D microstructure of a surface from a single image. By integrating our technique with traditional CAD tools, the surface modeling results have clear ‘micro’ surface structures. Firstly, a multi-pyramid image segmentation algorithm is applied on the single image to extract the objective region. Our segmentation algorithm is an energy-based model, and it is accelerated by multi-pyramid. In the following, we use a modified shape from shading (SFS) model to construct the 3D surface described in the extracted image region. Our method is a global SFS approach, which is based on a new energy function that represents the shading difference between the reconstructed image (obtained from the constructed 3D object) and the input image.
