手指静脉图像小波增强算法
Finger vein image enhancement algorithm based on wavelet transform
摘要
Abstract
According to the low⁃quality images of finger vein,a vein image filtering enhancement algorithm in the wavelet domain is proposed. In the algorithm,the wavelet transform is used,the parameter of the low frequency is enhanced in the frequency domain,and then the inverse wavelet transform is adopted to achieve the enhanced image. The experimental results show that the method can suppress noise perfectly,locate the image edge information accurately,improve the quality of image significantly,and enhance the extraction veracity of image features and identification accuracy. The algorithm obtained perfect efforts of image enhancement.关键词
