小区初搜为GSM系统中的一个关键过程，本程序为GSM小区初搜过程查找并解广播控制信道bcch的matlab程序，输入数据由采样数据得到，在转换成所需格式后进行处理。若其中包含bcch,则输出找到信息，并通过解调译码等工作解其中信息信息。若没有，则发出错误信息。内付算法详细说明文档(Area early in the search for the GSM system, a key process, the procedures for the GSM cell and the beginning of search process to find solutions BCCH Broadcast Control Channel of matlab procedures, input data from the sampling data, converted into the desired format in the post-treatment. If one includes bcch, while the output to find information and work through the demodulation decoding information in which information solutions. If not, then send a wrong message. Pay the algorithm in detail within the document)

基于肤色的人脸检测MATLAB源代码皮肤检测的最终目标是构建一个决策规则，并以此将图像中的像素划分为肤色和非肤色两类，一般通过引入一个衡量像素点颜色与“标准肤色”的距离而实现的，该距离是由相应肤色建模的方法决定的(Face detection based on skin color skin detection MATLAB source code for the ultimate goal is to build a decision-making rules, and use of the image pixels into skin and non skin types, usually by introducing a measure of the pixel color with the " standard colors" achieved the distance, the distance of the corresponding color from the decision modeling approach)
