Abstract

For practical computer vision applications using optical processors, filters to reduce clutter and detect candidate regions of interest (ROIs) in a scene are necessary before the class of an object can be determined. We discuss new morphological wavelet, Gabor, and rank-order filters to achieve clutter reduction, object detection, and image enhancement. All operations (and hence all low, medium, and high level computer vision operations) can be performed on the same optical correlator architecture with such new filters.
