带通滤波器的例子,详细的看，适合初学matlab和图形图像处理的例子(band pass filter example, the detailed, suitable for beginners Matlab and graphic examples of image processing)

基于SIFT的图像配准.最全版本。学习SIFT之必备资料。(image mosaic based on MATLAB)

可以看到圆心坐标和半径参数，在坐标中画出这个圆，编写画圆函数(You can see the center coordinates and the radius parameters, draw the circle in the coordinates, write the function to draw the circle)

该函数用来实现快速离散余弦变换。该函数利用2N点的快速付立叶变换来实现离散余弦变换(This function is used to implement fast discrete cosine transform. 2N points of the function using the fast Fourier transform to achieve the discrete cosine transform)

说明：  ORL人脸图像库，共40人，每人10幅图像，其中每人的前5幅作为训练样本，后5幅作为测试分类样本，统计正确分类率。分类准则为最近邻规则。 真实的图像尺寸为112x92，列向量堆积对应人脸库矩阵的每一列。 (ORL face image database, a total of 40 per 10 images, each of which the first five as training samples, after the 5 categories as a test sample, correct classification rate statistics. Classification criteria for the nearest neighbor rule. The real image size is 112x92, the corresponding column vector face database matrix accumulation of each column.)

易语言2D游戏引擎模块源码，易语言写的图形图象编程源码，很好的参考。(Easy language 2D game engine source module, easy language to write the graphics programming source code, a good reference.)

虹膜归一化的代码，只要给出定位好的虹膜图片，就可以很好的进行归一化，使用的极坐标变换。(Normalized iris code, as long as the position is given a good iris image, you can be a good uniform, the use of the polar coordinate transformation.)

SCPI语言及微机控制测量仪器编程,主要介绍scpi一些具体命令，说明及其实现。(SCPI language programming and computer controlled measuring instruments)

说明：  基于hessian矩阵的FrangiFilter，用于图像增强,常用于影像图像血管增强(FrangiFilter based on hessian matrix, which is used for image enhancement, is often used for image enhancement of blood vessels.)
