Paper Abstract

We propose a new approach for the 3D correlation. We compute directly the correlation integral without using the Fourier transform in the third dimension where the space bandwidth product of the sampled signal is small. We reformulate the 3D Fourier transform with a surface object model and the Lambert's Law. We discuss the means for recovering the object surface relief height function.
