surf特征提取算法，较sift优良，包括示例和实验图片，还有算法原文(surf feature extraction algorithms, the more sift fine, including examples and experimental images, as well as the original algorithm)

二维主成分分析。

在matlab上实现2ASK信号的调制，以及相干解调，并给出调制/解调后的信号波形。主程序名为ASKmod.m，调用子程序为T2F.m、F2T.m、 和LPF.m。(To achieve in matlab 2ASK signal modulation, and coherent demodulation, and given modulation/demodulation of signal waveform. Main program, called ASKmod.m, call subroutine to T2F.m, F2T.m, and LPF.m.)

Some matlab code for optimization

这是一个经典介绍时空相关K分布来对海杂波的仿真研究，值得借鉴和学习(This is a classic introduction time and space to K-distribution of sea clutter simulation studies, is worth learning and learning)

Newton Raphson method for mathematical operations in matlab language.

This program code is for compressing a file or image using Huffman coding without any built-in functions.

本代码为matlab平台开发用于计算图像的亮度。BRISQUE 算法对图像亮度去相关，提取亮度归一化系数向量与自然图像相应特征向量对比，以实现对图像失真评分。用matlab编写的功能函数，可编程使用。

基于像素的人流密度检测方法核心思想是，人群密度越高边缘像素点在图像中所占比例越大，人数越多的前景像素点占图像比例越高，即通过人群边缘像素来量化人群密度。前景人数与前景像素比例或者边缘像素比例成正比。因此，可以通过统计图像中人群前景的总像素数来确定人数。
