说明：  一个简单的计算器gui界面，实现加减乘除和三角函数计算。(A simple calculator GUI interface to realize addition, subtraction, multiplication and division and trigonometric function calculation.)

A fingerprint recognizing system is built with two principal components: the fingerprint admin istrator and the fingerprint recognizer. Fingerprints are identified by their special features such as ridge endings, ridge bifurcation, short ridges, and ridge enclosures, which are collectively called the minutiae.
