In shape from shading, contours play an important role as mathematical boundary conditions. On the other hand, contours are difficult to extract from an image. We propose 3D shape estimation method without boundary conditions through the integration of edge and shading information. Assuming that intensity edge corresponds to the initial estimation of shape edge, we can approximately use some constraints of shape edge. This algorithm based on the forward and approximated inverse optics models is able to estimate 3D shape with small number of iterations.
