Data hiding in the still image presets a variety of challenges that arises due to the way human visual system (HVS) works and the typical modifications that image undergoes. Additionally, still images priced a relatively small host signal in which to hide data. A fairly typical 8-bit picture of 200*200 pixels provides approximately 40 KB of data space in which to work. This is equivalent to around 5 seconds of telephone-quality audio or less than a single frame NTSC television.

利用Matalb为工具，以粒子群算法来优化bp网络程序。 (Use Matalb as a tool to PSO to optimize the bp network program.)

基于最小二元树的编码传输问题，用Matlab编程求解(Binary tree coding based on minimum transmission problem, solved with the Matlab programming)

SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.

这是一本MATLAB仿真参考书，对于初学者很有帮助(This is a MATLAB simulation of reference, useful for beginners)

说明：  一种快速的抗噪声模糊C均值图像分割算法 图像分割就是把图像分成若干个特定的、具有独特性质的区域并提出。该算法结合像素灰度值相似度和隶属度构造了一个新的空间函数。该空间函数用于更新成员关系，而成员关系又用于迭代地获取聚类中心。所提出的算法可以在较少的迭代次数下获得理想的分割结果，有效地降低了噪声的影响。(A fast anti noise Fuzzy C-Means Image Segmentation AlgorithmImage segmentation is to divide the image into several specific, unique areas and propose. In this algorithm, a new spatial function is constructed by combining the similarity and membership of pixel gray value. The spatial function is used to update the membership, and the membership is used to obtain the cluster center iteratively. The proposed algorithm can get ideal segmentation results with less iterations and effectively reduce the impact of noise.)
