OpenCV里面实现了许多特征点检测算法，我花了一段时间去学习和理解，写了一个文档在这，希望对大家又帮助。-OpenCV which implements many features detection algorithm, it took me some time to learn and understand, wrote a document in this, and I hope they help.

Real-Time Compressive Tracking是比较新颖的跟踪算法，这篇论文由香港理工大学张开华发表在2012年的ECCV之上，已有相应的Matlab和Opencv代码可供学习。
