(e) (f) Fig. 6. Results for Lenna image: (a) the original Lenna image, (b) 3-D plot of the reconstructed surface by the proposed neural-based method, (c) 3-D plot of the reconstructed surface by the Lambertain model with the estimated light source direction by Zheng and Chellappa’s method, (d) 3-D plot of the reconstructed surface by the Lambertian model with incorrect light source direction, (e) 3-D plot of the reconstructed surface by the Torrance‐Sparrow model with the estimated light source direction by Zheng and Chellappa’s method, and (f) 3-D plot of the reconstructed surface by the Torrance‐Sparrow model with incorrect parameters setting.
