这是一个surf特征匹配matlab程序，里面有实例和测试图像(This is a surf feature matching matlab program, there are examples and test images)

指纹识别 能够快速的识别出指纹库中的指纹，是否与输入的待检测的指纹相同，效果很好(Fingerprint identification can quickly identify the fingerprint of fingerprints, whether the same as the input fingerprint to be detected, the effect is very good)

读取一24位彩色图像，计算其以下图像特征： 1）灰度直方图 2）颜色直方图（RGB3个通道） 3）方向梯度直方图（HOG，将图像分成4*4 16个块，8个梯度方向） (Read a 24-bit color images, calculate the following image features: 1) Histogram 2) color histogram (RGB3 channels) 3) histogram of oriented gradients (HOG, the image is divided into 4* 4 16 blocks, 8 gradient directions))

扫描文件夹，通过文件大小和创建时间判断图片文件是否重复，并分类和重命名(Scanning folders to determine whether image files are duplicated, categorized and renamed by file size and creation time)
