ALGEBRAIC FEATURE EXTRACTION OF IMAGES FOR RECOGNITION

HONG ZIQUAN YANG JINGYU (Dept. of Computer Science, East-China Institute of Technology, Nanjing, 210014)  
In this paper, it is proved that the Singular Value (SV) feature vector has some important properties such as the invariance to the algebraic and geometric transformations, and the insensitiveness to noise, Therefore, th SV feature is very useful for describing and recognizing images. As an example, the SV feature vector is used to a problem of recognizing human facial images. The normal pattern Bayes classification model based on the Sammon optimal discriminant plane is constructed. The experimental results show that the SV feature vector has strong ability for the separating classes.
