Color pattern recognition with multi-wavelength FHF
Various kinds of color-image correlation detection with polychromatic matched spatical filter (MSF) have been investigated. A new type of lensless intensity correlation with Fresnel holographic filter (FHF) has been presented. A combined technique is proposed in this paper by which the color pattern recognition can be achieved with multi-wavelength FHF.
