摘要: 针对传统算法增强血管的各种问题,提出一种基于方向可调滤波器的血管图像增强方法。该方法以机器视觉系统为硬件平台,采用方向可调滤波器滤波,提取各方向静脉血管;利用小波变换进行图像融合,获取静脉高频信息;通过非线性反锐化掩膜,分层增强血管图像。实验结果表明:该方法能够有效抑制噪声,减少信息丢失,达到较好的增强效果。

Abstract: Based on the weakness of traditional image enhancement algorithms, an enhancement algorithm with steerable filter is put forward, which uses computer vision system as hardware platform. A steerable filter is applied for taking vein information in different directions. The wavelet transform is used to fuse image for high frequency information on vein. The nonlinear unsharp masking enhancement algorithm is used to escalate vein image. Experiment results show that the new algorithm can effectively suppress noise, reduce information loss and achieve better enhancement.

Key words: image enhancement, steerable filter, wavelet transform, unsharp masking enhancement
