基于SURF的仿射变换识别源代码，包括提取灰度图像的尺度不变特征（SIFT特征）-SURF-based affine transformation recognition source code, including the extraction of grayscale images scale invariant feature (SIFT features)

本程序针对光照变化和部分遮挡这两种情形,提出一种基于多帧视频图像的高稳定特征的交通标志识别方法。利用有交通标志的多帧视频图像的SURF特征建立bag of SURFs特征向量集,非常有利于对SURF研究的学者和研发人员进行学习和改造。-The program for the illumination changes and partial occlusion both cases, the paper proposes a high-s

基于SURF特征的印刷体汉字识别方法，可以将字倾斜矫正(A printed Chinese character recognition method based on SURF features)

用于图像的特征提取，运算速度快！比传统的SIFT算法快好多！(Feature extraction for images, fast operation! Much faster than the traditional sift algorithm!)
