In this paper a method to predetermine the value of detection peaks is demonstrated. The technique is based on a frequency-variant threshold in order to remove the intraclass terms and on a suitable factor to normalize the binary joint power spectrum. Digital simulations and experimental hybrid implementation of this method were carried out.6 p.application/pdfeng(c) Optical Society of America, 1994Reconeixement òptic de formesOptical pattern recognitioninfo:eu-repo/semantics/article87884info:eu-repo/semantics/openAccess
