Jpeg_code_decode

该程序包含两部迭代收缩阈值算法在几个方面的应用，包括图像，1范数和2范数的核心算法。(The program includes two parts of iterative shrinkage threshold algorithm in several aspects, including image, 1 norm and 2 norm core algorithm.)

解压arj文件的程序 (a program to deconde .arj files)

说明：  JpegLs源码,由UBC和HP在2000年联合开发(JpegLS project,developed by UBC and HP.)

对于做模式识别的朋友有很大的帮助~HAUSDORFF距离！！！！！(Pattern Recognition for doing a great friend to help ~ HAUSDORFF distance! ! ! ! !)

一系列展示图像压缩技术的源代码。包括有：使用块截断编码的图像压缩(Block Truncation)、基于高斯金字塔变换的图像压缩(Gaussian Pyramids)、基于离散余弦变换对图像压缩(Discrete Cosine Transform)、基于奇异值分解(SVD)的图像压缩(Singular Value Decomposition)。给出的代码还可以用于2D图像噪声消除。(Series show the source code for image compression technology. Include: use of block truncation coding for image compression (Block Truncation), Gaussian pyramid transform based image compression (Gaussian Pyramids), based on the discrete cosine transform image compression (Discrete Cosine Transform), based on singular value decomposition (SVD) image compression (Singular Value Decomposition). The code given 2D image can also be used for noise cancellation.)

上载了蜂窝网3种经典的无线定位算法，即fang算法、chan算法、taylor算法，大家相互交流学习。(Uploaded three kinds of classical cellular wireless location algorithm, that is, fang algorithm, chan algorithm, taylor algorithm, we share their knowledge with each other.)

说明：  用单片机来直接驱动步进电机很精确走小步子.(Using single-chip to directly drive stepper motor is very accurate take small steps.)
