Hybrid optical system for frequency-domain texture classification of imagery

摘要

An algorithm for segmenting images based on local texture properties and which requires only linear filtering operations has been described in a previous paper. We now report on the implementation of this algorithm in a hybrid electro-optical system which performs the linear filtering operations in the spatial frequency domain. Liquid-crystal video displays (LCDs) are used for input of the image and the frequency-domain filter. The system has the potential for rapid segmentation of simple images by texture properties.
