Description: 遗传+Gabor人脸/掌纹/指纹/虹膜等识别匹配程序。注意，该程序包含特征提取和匹配识别，但是对输入的图像要求最好是经过定位归一化的。没经过定位归一化的图像，识别效果较差。-Genetic+ Gabor Face/Palmprint/fingerprint/iris recognition, such as matching program. Note that the program contains the feature extraction and matching identification, but the input requirements of the best images is normalized positioning.
