Abstract :
An improved method for shape from shading is presented. With introduction of the adaptive attenuated factors, the results of the initial iterations fall into the region of the solution values as much as possible. Simulated tests show that the method makes a notable improvement over the well-known approach proposed by K. Ikeuchi and B.K.P. Horn (1981), not only on the correctness of the solution but also on the speed of the convergence. The case of the actual object is also discussed. The result is satisfactory
