基于c#指纹识别系统设计

The fingerprint identification system design based on c#

设计了一套精确、方便、人性化的基于c#指纹识别系统。指纹识别经过图像预处理、特征提取、特征匹配三步骤。运用高斯-拉普拉斯算子的边缘检测方法进行图像分割、Poincare法提取中心点以及端点、分叉点后去伪点进行特征提取以及结合节点与方向场的匹配方法进行匹配。经过调试得到的识别结果表明:运行稳定、实时性好、识别率高,达到了预期的目标并能够很好地满足实际需求,具有广泛的应用前景。

Design a set of precise, convenient and humanized fingerprint identification system based on c #.Fingerprint identification need image preprocessing, feature extraction, feature matching three steps. Using Gauss - laplacian edge detection method for image segmentation, Poincare method extracted the center as well as the endpoint, bifurcation point except the pseudo point after feature extraction, and combining with matching nodes and direction of field matching method. After debugging the recognition results show that the running stability, good real-time, high recognition rate, has reached the expected goal and can well meet the actual demand, with wide application prospect.
