实现matlab仿真生成ofdm系统，但不涉及信道估计等内容(Matlab simulation ofdm achieve generation systems, but does not involve channel estimation, etc.)

说明：  类间方差阈值分割算法的MATLAB实现。图像处理应用(Otsu threshold segmentation algorithm to achieve the MATLAB)

这个程序使用了遗传算法来优化点对点之间的轨迹度量。(This code proposes genetic algorithm (GA) to optimize the point-to-point trajectory planning for a 3-link (redundant) robot arm.)

Model Based Steganography Source code by Matlab

efficient LBP Local binary patterns (LBP) is a type of feature used for classification in computer vision. LBP is the particular case of the Texture Spectrum model proposed in 1990.[1][2] LBP was first described in 1994.[3][4] It has since been found to be a powerful feature for texture classification it has further been determined that when LBP is combined with the Histogram of oriented gradients (HOG) descriptor, it improves the detection performance considerably on some dataset

This source code use neural object to help student to understand the way to design the neural network using perceptron rule.

EMD分解，有效经验模式分解，有效经验模式分解，有效经验模式分解(EMD decomposition，EMD decomposition，EMD decomposition，EMD decomposition)

说明：  一种鲁棒的电子稳像系统，很有用处，帮助很大！(A robust electronic image stabilization system, very useful, very helpful!)

图像分割的方法有许多种，其中阈值分割的方法很常用，提供一种基于otsu算法的图像分割方法，很实用。(There are many kinds of method of image segmentation, threshold segmentation method is commonly used, provide a method of image segmentation based on otsu algorithm is very practical)
