构建了一种新的Harris多尺度角点检测算法,角点的图像配准算法的配准精度(Construction of a new multi-scale Harris corner detection algorithm, corner of the image registration algorithm for registration accuracy)

说明：  这是用matlab编写的关于人脸识别的基于pca的完整程序，非常实用(This is prepared using matlab on pca-based face recognition of the integrity of the process, very useful)

代码实现多目标粒子群算法，多目标粒子群算法是基于parato原则进行的目标优化实现的算法。而此文件就是多此算法的代码MATLAB的一种实现(Multiobjective particle swarm optimization (PSO) algorithm)

说明：  对于一些图像来说，常用的边缘检测算法有时候无法设立合适的阈值将它们的梯度较小的模糊边缘检测出来。为了解决这个问题，有两种解决方法：将图像方差标准化，拉大模糊边缘的梯度值，或通过设置sigmoid函数，将像素所在区域的信息传递到梯度值中去，对其进行调整，就能找到合适阈值，有效地将模糊边缘提取出来。本程序把这两种算法实现并与与传统算法进行了比较。(For some images, the commonly used edge detection algorithm sometimes can not be an appropriate threshold for the gradient of their smaller fuzzy edge detected. To solve this problem, there are two solutions: the image variance standardization, widening the fuzzy edge of the gradient value, or by setting the sigmoid function pixel region to disseminate the message to the gradient values to adjust, on the can find a suitable threshold, effectively extracted fuzzy edge. This procedure of these two algorithms with the traditional algorithm.)

视频采集，视频处理，视频跟踪，对视频监控很有帮助(Video capture, video processing, video tracking, video surveillance helpful)

说明：  二维功率谱密度计算程序 使用傅里叶变换，可以计算功率谱密度(Two dimensional power spectral density calculation program using Fourier transform)

精通MATLAB数字图像处理与识别 chapter11 代码(Proficient in MATLAB digital image processing and recognition chapter11 code)

说明：  左右圆偏振光的推导公式，与处理结果。传统意义上根据界面曲率的不同，对于确定的透镜，其正极性或负极性是确定了的。但根据等离子体天线方向角的改变，透镜的部分极性也随之改变，换言之，同一透镜中正负极性均存在且可控制。(Derivation formula and processing results of left and right circularly polarized light)

fisher 的lda算法，注释非常详细清晰(fisher)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))
