Paper Abstract

In this paper, a new and useful technique is presented to recover the object surface shape that contains discontinuities and additionally a wrinkled texture. In conventional photometric and fringe projection methods it is difficult to recover discontinuities and wrinkled texture, simultaneously. For carrying out the proposed technique, it is necessary to have the projection of a cosenuidal ruling with low and high frequencies. The technique recovers the discontinuities by filtering out low frequency in the Fourier spectrum. On the other hand, the wrinkled texture is detected by using the high frequency of the ruling spectrum. Finally, we use a joining algorithm to get the global object shape.
