  journal={IEEE Trans. Pattern Anal. Mach. Intell.},
Several recently developed techniques for reconstructing surface shape from shading information estimate surface slopes without ensuring that they a re integrable. This paper presents a n approach for enforcing integrability, a particular implementation of the approach, a n example of its application to extending a n existing shapefrom-shading algorithm, and experimental results showing the improvement that results from enforcing integrability. A possibly nonintegrable estimate of surface… CONTINUE READING
