We describe analytically the correlation plane, and we also introduce an original procedure to recognize the target by postprocessing the correlation plane. The performance of the methodology when the defocused images are corrupted by additive noise is also considered.5 p.application/pdfeng(c) Optical Society of America, 1997Reconeixement òptic de formesOptical pattern recognitioninfo:eu-repo/semantics/article138960info:eu-repo/semantics/openAccess
