Paper Abstract

Texture plays an important role in vision research and in many practical applications. Texture research has been wide in applied sciences and many methods for texture analysis have been proposed. To recognize texture a real-time modern optics may offer new tools, which is the theme of the present paper. We investigate the applicability of complex matched filter and phase-only filters to recognize textures. Natural textures of the Brodatz collection were used as the test samples. We show that optical correlators are useful in texture recognition. The recognition is based on the peak-to-correlation ratio, which is much higher for phase-only filters than for matched filters. However, if we consider output signal-to-noise ratio, the matched filter remains valuable.
