采用在线学习跟踪方式，对物体进行跟踪，代码用c++编写，库用的Opencv库，程序中包括了3个.h，3个.cpp，一个.main程序。-We have added two new state-of-the-art object tracking algorithms to OpenCV which can robustly track images patches across a video sequence and learn online (i.e., on-the-fly) as the

sift代码实现超详细，只有三部分，h，hpp，main避免代码分散看不懂,opencv下实现-sift code ultra-detailed, and only three parts, h, hpp, main avoid dispersion can not read the code, under opencv achieve
