VARGAS, A. et al. Reconocimiento de formas con un correlador óptico aplicado a imágenes desenfocadas: invariancia por medio de la selección y fusión de bandas. Rev. mex. fis. [online]. 2006, vol.52, n.3, pp.199-204. ISSN 0035-001X.

In this work, experimental result measuring the performance of a composite filter designed to solve the optical pattern recognition problem of defocus images is presented. We apply a methodology that considers optical decomposition of the input scene in frequency bands. In each band a pattern recognition filter is applied. Finally this information is fused by means of addition or geometric mean. We analyze both the individual information, and the fusion scheme. We also present results when total spectral information of the optical pattern recognition process is taken in to account.
