TAEMIN, Kim; BYOUNG-KWAN, Cho  e  MOON, Kim. Emission filter design to detect poultry skin tumors using fluorescence hyperspectral imaging. Rev Colom Cienc Pecua [online]. 2010, vol.23, n.1, pp.9-16. ISSN 0120-0690.

This paper presents an optimal emission filter of the fluorescence imaging system to detect skin tumors on poultry carcasses. The secure production of disease-free meat is crucial in the mass production environment. The fluorescence spectra have been gaining the practical use in many areas because the fluorescence response is very sensitive in detecting trace elements. The spectral features of the specimen are embedded across broad spectral bands and have been analyzed in various methods. We apply the linear discriminant analysis to determine the emission filter of fluorescence imaging system. It provides the optimal attenuation of emission wavelengths in terms of discriminant power. The attenuation values prioritize wavelengths to select significant spectral bands. With the optimal filter, skin tumor parts of chicken carcasses are enhanced saliently in resultant fluorescence images.

Palavras-chave : emission filter; hyperspectral imaging model; image enhancement; linear discriminant analysis; poultry skin tumors; spectrofluorimetry.
