MFC与opencv示例文档

建立工程见

http://www.opencv.org.cn/index.php/MFC%E4%B8%AD%E5%BF%AB%E9%80%9F%E5%BA%94%E7%94%A8OpenCV

在Doc类中添加变量

不要建立CImage m_image，改为

public:

IplImage *m_image;

加头文件：

#include "highgui.h"

初始化 m_image

CMFC_testDoc::CMFC_testDoc()

{

// TODO: add one-time construction code here

m_image = NULL;

}

在工程中加入以下两个文件

http://opencv-extension-library.googlec ... CvxWin32.h
http://opencv-extension-library.googlec ... xWin32.cpp

在stdafx.h中，加入#include "CvxWin32.h"

在CvxWin32.cpp中加入 #include "stdafx.h"

BOOL CMFC_testDoc::OnOpenDocument(LPCTSTR lpszPathName)

{

if (!CDocument::OnOpenDocument(lpszPathName))

return FALSE;

// TODO: Add your specialized creation code here

m_image = cvLoadImage(lpszPathName);

return TRUE;

}

BOOL CMFC_testDoc::OnSaveDocument(LPCTSTR lpszPathName)

{

// TODO: Add your specialized code here and/or call the base class

cvSaveImage(lpszPathName,m_image);

return TRUE;//CDocument::OnSaveDocument(lpszPathName);

}

在View类中添加显示图像代码

void CMFC_testView::OnDraw(CDC* pDC)

{

CMFC_testDoc* pDoc = GetDocument();

ASSERT_VALID(pDoc);

// TODO: add draw code for native data here

CvxWin32::DrawToHDC(pDoc->m_image,pDC->GetSafeHdc(),NULL);

}

如果需要实现canny

BOOL CMFC_testDoc::OnOpenDocument(LPCTSTR lpszPathName)

{

if (!CDocument::OnOpenDocument(lpszPathName))

return FALSE;

// TODO: Add your specialized creation code here

m_image = cvLoadImage(lpszPathName,0);

return TRUE;

}

void CMFC_testDoc::OnCanny()

{

// TODO: Add your command handler code here

cvCanny(m_image,m_image,50,150,3);

UpdateAllViews(NULL);

}
