说明：  图像识别的matlab程序实现，基于神经网络的图像识别(Image recognition matlab program implementation, image recognition based on neural networks)

Random Walker图像分割Matlab源代码，需要安装图形分析工具箱，地址http://eslab.bu.edu/software/graphanalysis/，给出了一个应用例子。(Random Walker Image Segmentation Matlab source code, need to install the graphical analysis toolbox, address http://eslab.bu.edu/software/graphanalysis/, gives an application example.)

基于空间几何约束的单目视觉物体测距 基于空间几何约束的单目视觉物体测距(Geometric constraints based on spatial objects ranging monocular vision Geometric constraints based on spatial objects ranging monocular vision)

遥感图像处理的基本操作：PCA变换、KT变换、直方图显示、彩色显示等(The basic operation of the remote sensing image processing: PCA transform, KT transform, histogram display, color display)

对图像进行二维离散小波变换, 变换级数大于等于3级,然后进行阈值化处理(阈值约为10左右),再统计系数中0的个数（百分比表示）并进行重构, 最后计算重构图像的峰值信噪比(PSNR). (Two-dimensional discrete wavelet transform image transformed series is greater than or equal to 3, and then processing thresholding (threshold of about 10 or so), then statistical coefficient in the number (expressed as a percentage) and to reconstruct the final calculation reconstructed image of the peak signal-to-noise ratio (PSNR).)

迭代收缩阈值算法和快速收缩阈值迭代算法求解Lasso问题(Iterative Shrinkage Thresholding Algorithm (ISTA) for LASSO problem)

序贯重要性采样——标准粒子滤波算法。可直接使用。(Sequential importance sampling- standard particle filter. Can be used directly.)

小波包分解，对信号能够高频，低频分解，能够得到不同频带范围的信号(zi dong shezhi yu zhi)

使用matlab实现的,基础单变量以及多变量梯度下降算法,和信号分类以及信号归一化部分算法，是机器学习领域最基本的代码，希望大家多多交流(matlab implementation of basic univariate and multivariate gradient descent and signal classification algorithms, machine learning basic code, hope that more exchanges)
