Gentle boost implementation

希望学习优化设计原理的同学能够好好利用这个资料啊(Want to learn the principles of optimal design students can take advantage of this information ah)

Turbo decoder under awgn channel. (The input is: uncoded bits,coded bits 1,coded bits2(interleaved), LLR from other source(if use only one turbo code ,fill all zero is ok), numbers of iterations, interleaver between two CC, source bit,decoder id(if used in parreled connected turbo codes), interleaver between two sources(under the situation of two turbo codes).)

createimage函数实现当前零水平集（演化曲线）在原图上的显示和嵌入函数u的重新初始(Createimage functions implementing the current zero level set (curve evolution in the display on the original) and inline function u initial again )

读入mit库的心电信号，并利用小波分析的方法去除其基线漂移(Read ECG mit libraries and to make use of wavelet analysis method to remove the baseline drift)

图像分割是进行图像理解与分析的基础,是图像工程技术中的一个重要问题, 也是图像处理的经典难题。彩色图像比灰度图像具有 更多的视觉信息, 因而受到了越来越多的重视。文章将彩色图像的分割技术分为三大类,并分别加以系统概括, 分析了各种方法的优缺点。(Image segmentation is the image understanding and analysis of the basis of the image engineering technology is an important issue, but also the classical image processing problems. Color image than the gray image with more visual information, which are more and more attention. Article will color image segmentation techniques into three categories, and to the system were summarized, analyzed the advantages and disadvantages of each method.)

matlab code is very good for health and wealth
