Study of Fusion Iterative Enhancement Algorithm of Hand Vein Image Based on Wavelet Transfor

A fusion iterative enhancement method based on wavelet transform is proposed to improve hand vein image in this paper. the method enhanced image in the frequency domain and spatial domain respectively. Experiment results indicated that this method not only enhanced the contrast ratio of the image obviously, but also removed the image noise effectively. the hand vein image processed by this method is a promising preparation for further hand vein recognition.
