Abstract: In order to discuss a novel feature vector describing quantitatively human palm patterns requires distinguishing six traditional kinds of patterns. These patterns from 302 palms belonging to 151 human subjects were described by the feature vector and analyzed using the Fisher discriminant analysis method. Results indicated an accuracy rate of 96% with this method. In particular four out of six palm patterns ( bridge line, simian line, sydney line, rudimentary creases) were classified correctly. The validation rate of 96% was achieved through the " Jackknife" method. In conclusion, the feature vector clearly and accurately describes six kinds of palm patterns.
