张正有的相机标定方法，有图片和程序，希望对相机标定的朋友有帮助(Zhang is some camera calibration method, there are pictures and procedures in the hope of the camera calibration of friends to help)

说明：  VC与MATLAB混合编程，示范例子 使用C++开发(VC versus MATLAB )

是一个matlab写的颜色空间的转换，不是matlab自带的那个文件。可以实现任意的两个颜色空间的转换(Write a matlab color space conversion, not a matlab file that comes with that. Can achieve any two color space conversion)

The use of fingerprints for identification has been employed in law enforcement for about a century. A much broader application of fingerprints is for personal authentication, for instance to access a computer, a network, a bank-machine, a car, or a home. The topic of this chapter is fingerprint verification, where "verification" implies a user matching a fingerprint against a single fingerprint associated with the identity that the user claims. The following topics are covered: history, image processing methods, enrollment and verification procedures, system security considerations, recognition rate statistics, fingerprint capture devices, combination with other biometrics, and the future of fingerprint verification.

SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.

this is a code which can get the expected value of choosing 52 cades.
