用全选主元高斯消去法求解N复系数阶线性方程组AX=B

识别0~9阿拉伯数字，输入为yuv格式图片。Demo共分为两个程序，create_number和number_identification。create_number程序随机生成一个10位数，并建立YUV文件，生成的文件存放位置为../test_data/random_number.yuv。yuv为像素域的色彩空间，也就是图片解压后的结果，是常用的数字图像处理的色彩空间。number_identification程序对random_number.yuv文件里的数字进行识别，打印输出结果。

应用背景此代码是解决二次相关保理。关键技术“二次”是一个多项式，看起来像“ax2＋bx＋c”，“一”，“乙”，和“丙”只是数字。为了容易保理的情况下，你会发现2个数字，将不只是乘法相等的术语“，而且加起来等于“乙”，在x-term系数。

资源描述Abstract Considering rapid developments in the technologies of both radio-frequency identification (RFID) systems and wireless sensor networks (WSN), an integration of the two technologies may lead to the formation of an RFID-enhanced WSN which would possess improved functions and capabilities. In the RFID-enhanced WSN, many reader-enhanced nodes have increasingly been employed. In such networks, RFID data contains a lot of duplication, because the same tag may be read multiple times, and collision may occur among readers, while energy constraints are also a serious problem. These three could in turn cause serious problems. In this paper, we have proposed our CSMA-based algorithm since it is light, efficiently minimizes all kinds of reader collision, and eliminates the duplicate data. For this purpose, we have used a separate control channel and a tag ID forwarding mechanism with a special co

检查图片中属于人类肤色的区域。输入为yuv格式图片，目前可以识别黄种人的肤色区域。主要用到椭圆模型的色彩识别算法，在yuv色彩空间中，将近似黄种人肤色的色彩，用uv二维空间中的椭圆区域来表示。
