%X The purpose of the present study is to investigate the presence of multifractal behaviors of the palmprint.By studying the probability distribution and the partition function,we show that the palmprints possess multifractal characteristics.The width spread,the maximum of multifractal spectrum,and a parameter which describes the asymmetry of the spectrum are proposed as the distinguishing palmprint features.This may provide some factors of importance for palmprint recognition,and shed some light on the problem of biometric recognition.
