摘要给出极坐标形式的复变函数的可微性充要条件的证明及其重要应用。
First of all , we select a referrence point pair of the input image and the template image . and then we transform the minutiae positions into polar coordinates . finally , we match the input image with the template one to judge whether these two images are captured from the same finger
首先，找到输入图像和模板图像的参照点对，然后将两幅图像中的细节特征点相对于各自的参照点转化为极坐标形式，最后进行比对，确定两幅图像是否来自于同一手指。
