一种特征描述算子，功能和sift类似，但比sift速度更快，有重要的研究价值-A characterization of operators, functions and sift similar, but faster than sift, has important research value

颜色恒常性和sift特征算子相结合的算法，主要用于计算机视觉中的特征提取，匹配和识别等。-Characteristics of color constancy and sift algorithm combining operators, mainly for computer vision, feature extraction, matching and identification.

C++的源码关于slam程序的，可以在windows下调试，该代码主要针对slam中sift的计算问题，将sift算子的计算放到GPU上进行，大大提高了源码的运行速度-this is an project about slam .and we put the sift in GPU calculate.It is very importan for us to improve the slam speed.
