之前学过点socket编程，但是忘得差不多了，最近又重新看了一下。看本文章的人可以先了解一下socket编程的基本过程，网上有很多，博主在此就不赘述了。

直接上干货。方便刚学socket 使用opencv的新人。注：首先需要配置opencv的环境才可用啊。高手勿喷！

博主用的环境为：opencv2.4.13 + vs2013

客户端的程序：

#include <WINSOCK2.H>    #include <iostream>    #include <stdio.h>    #include <cv.h>    #include <opencv2/core/core.hpp>    #include <opencv2/highgui/highgui.hpp>    #include <opencv2/imgproc/imgproc.hpp>    using namespace cv;  using namespace std;    #pragma  comment(lib,"ws2_32.lib")      int main(int argc, char* argv[])  {      WORD sockVersion = MAKEWORD(2, 2);      WSADATA data;      if (WSAStartup(sockVersion, &data) != 0)      {          return 0;      }        SOCKET sclient = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);      if (sclient == INVALID_SOCKET)      {          printf("invalid socket !\n");          return 0;      }        sockaddr_in serAddr;      serAddr.sin_family = AF_INET;      serAddr.sin_port = htons(8888);      serAddr.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");      if (connect(sclient, (sockaddr *)&serAddr, sizeof(serAddr)) == SOCKET_ERROR)      {          printf("connect error !\n");          closesocket(sclient);          return 0;      }      //读取图像并发送        Mat M1 = imread("D:\\lena.bmp",0);//载入图片        Mat M2(M1.rows, M1.cols, CV_8UC1); //放置灰度图像        printf("%d*%d\n", M1.rows, M2.cols);      M2 = M1.clone();      int i, j;      char sendData[1000000] = "";      cvNamedWindow("client", 1);      for (i = 0; i < M1.rows; i++)      {          uchar *data = M2.ptr<uchar>(i);          for (j = 0; j < M1.cols; j++)          {              sendData[M1.rows * i + j] = (char)data[j];          }      }      imshow("client", M1);      send(sclient, sendData, 1000000, 0);//发送        cvWaitKey(0);//任意键发送        cvDestroyWindow("client");      closesocket(sclient);      WSACleanup();      return 0;  }

服务端的程序：
