Generalized morphological operator can generate less statistical bias in the output than classical morphological operator. Comprehensive utilization of spectral and spatial information of pixels, an endmember extraction algorithm based on generalized morphology is proposed. For the limitations of morphological operator in the pixel arrangement rule and replacement criteria, the reference pixel is...
The performance of an automatic fingerprint authentication system relies heavily on the quality of fingerprint images. Besides, the effective evaluation and quality classification of fingerprint images is of paramount significance in the applicability research of fingerprint recognition algorithm. In this paper, an effective quality classification method for fingerprint image based on neural network...
