type modifier (typespecifier). It is designed to modify variables that are visited and changed by different threads. Variables defined by the volatile type are extracted directly from the corresponding memory each time the system uses it, rather than using the cache. After using the volatile modifier member variable, the values of the variables that all threads see at any time are the same. A demo sample using volatile is given below. public class mythread Impl ements Runnable

OpenCV, a cross-platform computer vision library based on BSD licensing (open source), can run on Linux, Windows, Android, and Mac OS operating systems. It is lightweight and efficient-consisting of a series of C functions and a small number of C + + classes, and provides interfaces for languages such as Python, Ruby, and Matlab, and implements many common algorithms for image processing and computer vision. OpenCV in C + + language, its main interface is also C + + language, but still retains a
