3 p, 1.9 MB Detection theory approach to multichannel pattern location / Guillaume, M. (Ecole Nationale Supérieure de Physique de Marseille) ; Réfrégier, Ph. (Ecole Nationale Supérieure de Physique de Marseille) ; Campos Coloma, Juan (Universitat Autònoma de Barcelona. Departament de Física) ; Lashin, Vladimir (Universitat Autònoma de Barcelona. Departament de Física)
We propose and assess new algorithms for detecting and locating an object in multichannel images. These algorithms are optimal for additive Gaussian noise and maximize the likelihood of the observed images. [...]

3 p, 1016.2 KB Color pattern recognition with circular component whitening / Moreno Soriano, Ignacio (Universitat Autònoma de Barcelona. Departament de Física) ; Kober, Vitaly (Universitat Autònoma de Barcelona. Departament de Física) ; Lashin, Vladimir (Universitat Autònoma de Barcelona. Departament de Física) ; Campos Coloma, Juan (Universitat Autònoma de Barcelona. Departament de Física) ; Yaroslavsky, Leonid P. (Tel Aviv University. Department of Interdisciplinary Studies) ; Yzuel Giménez, María Josefa (Universitat Autònoma de Barcelona. Departament de Física)
Polychromatic object recognition based on circular whitening preprocessing of red–green–blue components and multichannel matched filtering is described. Computer simulations and experimental results are provided to facilitate recognizing a color target among objects of similar shape but with different color contents. [...]
