混合粒子群算法具有很好的计算精度及时的收敛(Hybrid particle swarm algorithm has good convergence accuracy in a timely manner)

a program compiled by matlab to computer more than 30 of gravity parameter from a gravity modle

audio signal processing and recognition,是一本台湾张智星教授所写的关于语音处理的书籍，网上有另一个版本书名叫《audio processing》，和这个有点区别，两个结合看效果会更好！(audio signal processing and recognition, is a book written by Professor Zhang Zhixing Taiwan books on speech processing, there is another version of the online book called "audio processing", and this little difference, the two combined to see better results!)

提出了一种基于小波变换可抗击几何攻击算法。在水印嵌人 部分# 首先对宿主图像进行小波分解 、 嵌人水印, 再通过余弦变换求得该水印图像的一个特征向量, 利用该特征向量和水印 信息通过12 31 函数生成一个二值逻辑系列, 将该序列作为密钥/ 水印提取部分为# 对待测的图像进行小波变换, 再通过余 弦变换求得待测图像的一个特征向量, 利用该特征向量和密钥通过1 2 4 1 函数提取出水印。(Proposed based on wavelet transform algorithm can be against geometric attacks.# Watermark embedded in the first part of the host image wavelet decomposition, embedded watermark, and then through the cosine transform of the watermarked image obtained by a feature vector, using the feature vector and the watermark information through 1231 to generate a binary logic function series, the sequence as the key/watermark extraction part is# treated transform measured image, and then obtained through the cosine transform the image of a feature vector under test, using the feature vector and the key function by 1241 to extract the watermark .)

自适应滤波的代码和文档，毕业设计论文以及用户文档(Adaptive filtering of code and documentation, graduation thesis design and user documentation)

This a two dimensional level set code that constructs signed distance function using a first order Godunov scheme.

This program segment the tumor present in brain image. Sine brain symmetric about central axis brain is divided into 2 equal halves about the central axis.Histogram of both the part is taken. based on the histogram threshold is set.Result of segmentation is the segmented tumor.
