peakfinder
This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if the signal is noisy many spurious peaks are found.

JAVA文件压缩与解压缩实践
说明: 本系统运用LZ77字典算法、懒惰匹配算法和Huffman编码算法,使用Java语言在Jbuilder2006环境下设计了使用GZIP算法对文件压缩与解压缩的实现程序。用户可以根据自己的需求,使用此程序方便地对文件进行压缩或者解压缩操作。(This system uses LZ77 dictionary algorithm, lazy matching algorithm and Huffman coding algorithm, and uses Java language to design the implementation program of gzip algorithm for file compression and decompression under the environment of JBuilder 2006. Users can use this program to compress or decompress files conveniently according to their own needs.)

speckle
对图像进行斑点噪声的添加,用方程f=f+n*f将乘性噪音添加到图像f上,其中n是均值为零,方差为var的均匀分布的随机噪声。(Image speckle noise addition, the equation f = f+ N* f will be added to the multiplicative noise on the image f, in which n is zero mean, variance var of the uniform distribution for the random noise.)
