❷ 易语言怎么做视频监控求源码！QAQ
首先，易语言高！成千上万的源码可以借鉴！
其次够底层，直接嵌入汇编！用上黑月插件，编译够小！
易语言的独特模块，拿来就用！
_
破解，病毒，游戏辅助，基本都是在反编译，掌握了程序基本情况之后，在写程序！！
写内存，读内存，进程注入，这些技术在其他编程语言实现你的看各种文档！ 而易语言，各种注入模块，驱动读写内存，都是现成的！
而其他语言，如C语言，你写的时候，很多时间，都是在了解c的各种库。本来你只想吃馒头，用c你就得了解包头的烹饪方法！如果，你还需要互动的界面的话......成本太高了！
易语言很多时候其实只是负责UI，很多动态库都是其他语言编写的，易语言负责调用整合！
可以说，易语言，在开发小程序，有天然的优势！

❺ 最近，想用MFC编个对话框，能够实时显示摄像头捕捉的镜头！谁有源代码，能否发我一份吧！感激涕零啊……
现在在vc上采集视频常用的方法有三：vfw，directshow，opencv
你是要进行图像处理的话推荐opencv（具体参考：于仕琪，opencv教程基础篇中的例3-6，稍作修改，估计就能用于你的工程）
下面贴出我自己编的一个小工程：如有疑问，E-mail：[email protected]
进行opencv的预备操作你要看那本书和逛opencv中文网
如有问题可以和我讨论（我也是菜鸟，刚为解决了这个问题窃喜不已）。
1.新建mfc对话框工程，在其中添加一个picture控件，除了ID以外什么都不用改
2.在对话框头文件（没有Dlg那个）中添加（最好是在“#include "resource.h" // main symbols之后”）：
#include "cxcore.h"
#include "cvcam.h"
#include "windows.h"
#include "cv.h"
#include "highgui.h"
3.在工程-》设置-》选择所有配置-》link（连接）-》对象/库模块-》中添加：
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib cxcore.lib cv.lib ml.lib cvaux.lib highgui.lib cvcam.lib
4.在需要触发摄像头显示的地方添加：
void CVideomfcDlg::OnButton1()
{
// TODO: Add your control notification handler code here
int ncams = cvcamGetCamerasCount( );//返回可以访问的摄像头数目
HWND MyWin=::GetDlgItem(m_hWnd,IDC_VIDEO); //获得控件句柄（IDC_VIDEO就是图片控件）
cvcamSetProperty(0, CVCAM_PROP_ENABLE, CVCAMTRUE); //选择第一个摄像头
int width=240;
int height=240;
cvcamSetProperty(0,CVCAM_PROP_WINDOW, &MyWin); // Selects a window for
cvcamSetProperty(0,CVCAM_RNDWIDTH, &width);
cvcamSetProperty(0,CVCAM_RNDHEIGHT, &height);
cvcamSetProperty(0, CVCAM_PROP_CALLBACK, callback1);
//回调函数将处理每一帧
cvcamInit( );
cvcamStart( );
}
5.改变显示的图像序列大小，在窗口属性设定了以后，添加如下代码：
int width=320; //这个就是需要显示的窗口大小
int height=240; //根据自己需要选择
cvcamSetProperty(0,CVCAM_RNDWIDTH, &width);
cvcamSetProperty(0,CVCAM_RNDHEIGHT, &height);
6.在对话框类中添加callback成员函数（注意，在添加函数的时候，一定要选择static，不选的话你就自己郁闷去吧，反正我是为了这个郁闷了2个礼拜）
void CVideomfcDlg::callback1(IplImage *image)
{
IplImage* image1 = image;
int i,j;
assert (image);
//获取当前系统时间
SYSTEMTIME st2=;
GetLocalTime(&st2);
char sss[18]=; //这个是用来存储所要保存的图片名的，用的是一个笨办法，先定义，再修改其中的数组值。
sss[7]=st2.wHour/10+48; //获取系统当前小时
sss[8]=st2.wHour%10+48;
sss[9]=st2.wMinute/10+48; //获取系统当前分钟
sss[10]=st2.wMinute%10+48;
sss[11]=st2.wSecond/10+48; //获取系统当前秒
sss[12]=st2.wSecond%10+48;
cvSaveImage(sss,image1); //使用系统当前时间为名称（XXXXXX.jpg）存储图片
}
ps：你还需要在c盘根目录下建立一个叫1的文件夹保存图片。
祝你成功！
❻ android 实时监控硬件摄像头如何实现 求个源码
实时监控还是比较厉害的，后台拍摄记录？不懂是个什么意思，程序调用摄像头拍照还是比较简单的。
❼ 求“VC++实现的支持摄像头和图像的人脸识别系统”源码和报告
实现支技摄像头和八图像人脸识别二维码扫描器实现梦想的声音好大。
❽ 求 在网页中打开查看局域网内的摄像头的监控画面 的例子（源码），请不吝赐教，在下感激不尽。
这是正解。。。。
那个监视系统要兼容你用网页打开的操作。
如果不兼容，打死我也没办法，你用的那个软件，如果支持这种调用，应该会写出来。并且会写出详细调用方法、提供源码或直接提供一个网页。
你的监视器是什么端口？网络摄像头么。。
厂商不是傻X，有网页调用的方法，绝对会立刻发布。。。
lz，偶爱莫能助。。。。
