Paper Abstract

The 4-D Wigner distribution function (WDF) of 2-D images has been generated, filtered, and inverted through a hybrid optical-digital processor. In this way, different spatially variant filtered images have been obtained. The processor generates optical and sequentially the spatial samples of the distribution. Each one of this samples can be modified in a different way, multiplying it by different masks. The filtered WDF is inverted also via optical. Then, a digital image processor selects the information associated with each filtered image point.
