图像特征提取，有SIFT、BOW、VLAD、LBP、HOG、FishVector、gist、Metric、colorhist。(Image feature extraction, including SIFT, BOW, VLAD, LBP, HOG, FishVector, gist, Metric, colorhist.)

说明：  结合图像处理MATLAB的基本原理和知识，详细介绍了手指静脉预处理，图像分割，静脉纹路分割，滤波去噪，细化等相关内容。(Combined with the basic principle and knowledge of image processing, this paper introduces the finger vein pretreatment, image segmentation, vein vein segmentation, filtering and denoising, thinning and other related contents in detail.)

用于姿态初始化（position initialize）(for position initializing)

说明：  基于gabor和chirp原子的匹配追踪算法论文简介！共同进步 又更多需要可以加610521482！(Comparing gaussian and chirplet dictionary.Matching pursuit method!)

说明：  仿真获取四幅互差半个像素的低分辨率图像，利用反演解析算法重建出一副高分辨率图像，属于亚像元技术或者超分辨率技术。(Simulation Interoperability poor access to four half-pixel low-resolution images, the use of inversion algorithm for the reconstruction of an analytic high-resolution images, belong to sub-pixel super-resolution technology or technology.)

softcast的2d dct实现，先对图像转灰度图，得到的亮度信号矩阵做DCT 变换(softcast of 2d dct implementation, the first image to grayscale, luminance signal obtained by DCT transformation matrix do)

rgb颜色空间与hsi颜色空间转换的一段MATLAB代码。(a matlab code rgb space to hsi space or return.)

获取图像的LBP特征：对图像的原始LBP模式、等价LBP模式、旋转不变LBP模式，以及等价旋转不变LBP模式的LBP特征进行提取以及显示(Obtaining LBP features of images: extracting and displaying the original LBP pattern, equivalent LBP pattern, rotation invariant LBP pattern and equivalent rotation invariant LBP pattern of images)

图像阈值化分割,图像阈值化分割,图像阈值化分割(Image thresholding segmentation.Image thresholding segmentation.Image thresholding segmentation)

说明：  该代码的主要功能是图像边缘检测，利用霍夫变换确定圆的位置，并进行缺陷定位着色等操作(The main function of the code is image edge detection, using HOF transform to determine the location of the circle, and the location of defects such as coloring operations)
