                         estimation through the matching of photometric stereo images. By 
                         considering the general solution of the differential equation 
                         which relates surface depth to the disparity map produced by the 
                         matching process, we are able to obtain a more consistent 
                         formulation of such disparity-based approach to photometric 
                         stereo. Also, we introduce a multiscale matching procedure, based 
                         on a new stochastic metaheuristic for combinatorial optimization, 
                         which yields more reliable disparity maps in shorter processing 
                         times. Finally, we employ a simple least-squares regression in a 
                         calibration strategy for estimating the parameters required by our 
                         reconstruction approach. Shape-estimation experiments with real 
                         images are presented.",
