Abstract
In this article, we propose to return to the simplest optical architecture and to transfer all the recognition intelligence in to the filter design. However the use of such a filter to carry out multiple correlations in parallel poses the problem of product space bandwidth limitation in the filter plane (Fourier plane): information on references is injected into the filter by a frequentially multiplexing of the references constituting the training base. From this point of view, we propose an optimization of the segmented filter in order to increase its performance and its capabilities.
