【图像分割】基于方向谷形检测实现静脉纹路分割附MATLAB代码
2022-07-28 17:09:00 【Matlab科研工作室】
1 内容介绍
一种基于方向谷形检测的指静脉图像分割方法及其系统,终端,包括以下步骤:步骤1,接收图像采集模块采集的指静脉图像;步骤2,对截取的指静脉图像进行脊波变换作图像增强处理;步骤3,针对增强处理后的静脉图像提取谷形区域;步骤4,将得到的静脉图像分为三个区域:背景区,模糊区,前景区,并对该三个区域进行三次的阈值分割处理;步骤5,将得到的分割图像进行边缘检测,输出处理后的分割图像.本发明的系统及方法根据静脉图像中的蕴涵的一些内在信息如形状,阶跃性质,方向等特点而提出的一种算法,能够准确的提取图像中感兴趣的静脉特征,减少提取错误特征.
