3 p, 255.9 KB Optical pattern recognition based on color vision models / Millán García-Varela, M. Sagrario (Universitat Politècnica de Catalunya) ; Corbalán Fuertes, Montserrat (Universitat Politècnica de Catalunya) ; Romero, J. (Universidad de Granada. Departamento de Óptica) ; Yzuel Giménez, María Josefa (Universitat Autònoma de Barcelona. Departament de Física)
A channel transformation based on opponent-color theory of the color vision models is applied to optical pattern recognition so that the conventional red, green, and blue (RGB) channels are transformed into bright-dark, red-green, and yellow-blue (ATD) channels. [...]

We mathematically analyze the phase-only hologram constructed by taking the phase corresponding to the linear combination of two weighted phase functions. We show that this phase-only hologram may be written as a new linear combination for the original phase functions with new weights. [...]
