人脸检测的方法很多，kl是其中比较有效的一种。本代码主要是使用pca的方法进行人脸检测，可以检测出人脸的大小位置，数目，大小(Face Detection many means kl is a more effective. The code is the use of the method pca Face Detection can detect the size face location, number, size)

图像质量标准，psnr及相关系数，很实用(Image quality standards, psnr and correlation coefficients, it is practical)

用来将一个指纹图片切成指定像素大小的片段，并将计算他的方向场和系数(Used to cut a fingerprint image into the specified pixel size pieces, and calculates the direction of the field and the coefficient )

毕业设计的程序 用VC++6.0做的 主要是测试几个边缘检测算子的效果(Graduate programs designed to use VC++ 6.0 to do is to test several of the main edge detection operator effect)

说明：  OFDM中的降低PAPR中的pts方法的程序，里面包括随机，交织，相邻分割(it is a simulation papr of pts)

随着红外成像技术的发展，红外小目标检测在军事领域有越来越重要的应用。以此为背景，研究了天空、海面、大地等各种背景下红外视频中弱小目标的检测问题。 (With the development of infrared technology,dim small targets detection play a more and more important part in the military. The problem of dim small targets detecting in a infrared video with the background of the sky,the sea and the groundhas been studied. )

图像中数字水印matlab编码，水印的嵌入提取及嵌入强度(Digital watermark image matlab coding, the embedded watermark extraction and embedding strength)

图像融合评价程序，通过均值，标准偏差，熵，梯度，相关系数，光谱扭曲度等多个指标对融合图像进行评价比较。(image fusion evaluation procedures, the mean, standard deviation, entropy, gradient, and the correlation coefficient. spectral distortion degree of integration of various indicators to evaluate the comparative images.)

这是通过径向偏振贝塞尔高斯光束聚焦一个组合 二进制相光学元件和高数值孔径的镜头。(This is achieved by focusing a radially polarized Bessel–Gaussian beam with a combination of a binary-phase optical element and a high-numerical-aperture lens.)

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.)
