支持向量回归

C#实现WebSocket源码（c#写的服务端html写的客户端）WebSocket 协议在2008年诞生，2011年成为国际标准。所有浏览器都已经支持了。它的最大特点就是，服务器可以主动向客户端推送信息，客户端也可以主动向服务器发送信息，是真正的双向平等对话，属于服务器推送技术的一种。其他特点包括：（1）建立在 TCP 协议之上，服务器端的实现比较容易。（2）与 HTTP 协议有着良好的兼容性。默认端口也是80和443，并且握手阶段采用 HTTP 协议，因此握手时不容易屏蔽，能通过各种 HTTP 代理服务器。（3）数据格式比较轻量，性能开销小，通信高效。（4）可以发送文本，也可

【实例简介】使用方法: 1. 准备一个空的U盘，使用 UltraISO 制作DOS盘，运行 UltraISO 打开 dos71usb.img 镜像文件， 点击 【启动】菜单-=>【写入硬盘映像】-=>【硬盘驱动器】中选择U盘盘符然-=>点击【写入】 写入完成后把 MAC149F 目录拷到U盘中，重启电脑。 2. 入进BOSS设置U盘启动(不懂就度娘)重启, 选择第三项加载USB驱动，接下来就是要输入命令啦。 输入 cd mac149f 进入MAC149F目录； 输入 mac c *** 后面的***是你要改新的MAC地址，如：mac c 001132AAAAAA； 提示“PGEFuse is Sucessful！！”表示已经修改成，重启电脑就可以了； 如果不行就再试 macu c *** 或 macu2 c *** ; PS：发现有些可网卡无法使用mac c *** 我朋友的RTL8111f网卡，(自己的可以) 那么你可以 R8111GEF 下的 PG8168.EXE 来进行修改，命令如下： cd r8111gef gb8168.exe /efuse /nodeid *** (***是新的MAC) 支持大部分网卡：RTL8168，RTL8168EF，RTL8136，RTL8136EF，RTL8139，ULi5263，ULi5261，SiS，INTEL5266DC，RTL8169，BCM57781，INTEL82579，INTEL82583，INTEL82574_BMC，INTEL82574，AR8161，INTEL217，INTEL210，INTEL217V，INTEL211.32，INTEL211.39，RTL8168DP，AR8171，AR8111GEF，INTEL210.31，INTEL350.151F，INTEL350.1521，INTELX540.1528，INTELX540.

【实例简介】在图像测量过程以及机器视觉应用中，为确定空间物体表面某点的三维几何位置与其在图像中对应点之间的相互关系，必须建立相机成像的几何模型，这些几何模型参数就是相机参数。在大多数条件下这些参数必须通过实验与计算才能得到，这个求解参数的过程就称之为相机标定（或摄像机标定）。无论是在图像测量或者机器视觉应用中，相机参数的标定都是非常关键的环节，其标定结果的精度及算法的稳定性直接影响相机工作产生结果的准确性。因此，做好相机标定是做好后续工作的前提，提高标定精度是科研工作的重点所在。
