    In general, all the main parts for my project worked well.
    At the beginnning,  it was hard to figure out what M and b as well as M and v stood for from the project specification. It was solved after I found out they were for two different functions--compute normal and compute depth.
    The reconstructed surface has a little problem with the left edges (as shown in the third views of Buddha reconstructed surface and also the other two image sets). It could be my problem of the algorithm to compute M matrix and V vector, or it was the defect of this application which I'm not sure of. But I think if we can use images shoot from more than one angle (more light angles), we can see better reconstructed 3D images.
