cvBlobslib 元件

目地:可計算物件面積跟長跟寬之類...........

比較詳細請看 Lubosz Sarnecki的Github

https://github.com/lubosz/cvblobslib

1.

常應用於AOI錫球之類................

for (int i = 0; i < blobs.GetNumBlobs(); i++ )
{
    currentBlob = blobs.GetBlob(i);
     //dataGridView1->Rows->Insert(0,"1","2","3");
     //p1.x =(int)currentBlob->MinX();
    //p1.y =(int)currentBlob->MinY();
     //p2.x =(int)currentBlob->MaxX();
    //p2.y =(int)currentBlob->MaxY();
     dataGridView1->Rows->Insert(0,currentBlob->GetID(),currentBlob->Area(),currentBlob->Perimeter());
}

人臉辨別

以目前來看大部分都用

EigenFace
Fisherfaces
Local Binary Patterns

來辨別人臉 ~ 所以彙整一些別人寫的資料範例

1.人臉的圖示可以到下面網址下載

AT&T Laboratories Cambridge (劍橋實驗室所提供):

www.cl.cam.ac.uk/research/dtg/attarchive/facedatabase.html

2.測試一下下載的圖片

3. 使用OpenCV 2.1 + VS 2008工具

Itay Klein的github範例網址:

https://github.com/Kleinitay/vtago

4. 使用 OpenCV 2.4.9 + VS 2012

Philipp Wagner 的github範例網址:

https://github.com/bytefish/libfacerec

5.整合大部分出來的樣式都會像這樣子

另外其他參考:

OpenCV 身分證輪廓抽離

假設

1.鏡頭擷取距離固定不變

2.光源不變

身分證樣式用內政部拿來做身分證樣本的圖片

1.首先利用RGB分離

2.

code:

int main(int argc, char** argv)
{
      IplImage* img = cvLoadImage("SS1.jpg");
      IplImage img01 = cvCloneImage(img);
    cvNamedWindow("gray");
    cvNamedWindow("img");
    cvNamedWindow("img01");
    cvNamedWindow("img02");
      IplImage gray=cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,1);
      cvCvtColor(img,gray,CV_RGB2GRAY);
      IplImage* pColorImg = cvCreateImage( cvGetSize(img), 8, 3 );
      CvMemStorage* storage = cvCreateMemStorage(0);
      CvSeq* lines = 0;
      cvErode(gray,gray,0,3);
      cvDilate(gray,gray,0,1);
    FillInternalContours(gray, 200,img01);
      IplImage *img02 = cvCloneImage(img01);
    int Height=cvGetDimSize(gray,0);
      int Width=cvGetDimSize(gray,1);
      cvSetImageROI(img02, cvRect(0,0,Width,Height/2.5));
    // B G R
    cvAddS(img02, cvScalar(-255,-255,-255),img02); // 把值加入到另一個圖片裡
    cvResetImageROI(img02);
      cvShowImage("gray",gray);
    cvShowImage("img",img);
    cvShowImage("img01",img01);
    cvShowImage("img02",img02);
    cvWaitKey(0);
    cvDestroyWindow( "gray" );//銷毀視窗
    cvDestroyWindow( "img" );//銷毀視窗
    cvDestroyWindow( "img01" );//銷毀視窗
      cvDestroyWindow( "img02" );//銷毀視窗
      cvReleaseImage( &gray ); //釋放圖像
    cvReleaseImage( &img ); //釋放圖像
    cvReleaseImage( &img01 ); //釋放圖像
      cvReleaseImage( &img02 ); //釋放圖像
      return 0;
    }

3.流程為圖示內所標示~

因為那些函式網路上已經有人有寫了~所以大約流程簡述一下

使用函式 cvErode ~ cvDilate ~ cvAbsDiff ~ UnsharpMask ~ FillInternalContours

(google就可以找到了)

Mac OS Xcode 6 + OpenCV

作業環境:

OS : Mac OS 10.8

Xcode 6 => CMake 2.8.12.2 => OpenCV 2.4.9 => Homebrew

1.網址:

http://opencv.org/downloads.html

下載 Version 2.4.9 => OpenCV for Linux/Mac

2. 下載 http://www.cmake.org/download/

CMake 2.8.12.2 ~ 下載好之後點開 ~ 會變成UI畫面

3. where is the source code =>用OpenCV解壓縮到我的文件夾內的opencv-2.4.9

where to build the binaries => 我在opencv 裡面有創一個release資料夾的說

之後按configure => Generate

4. 在Terminal安裝 Homebrew 工具

指令:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

5. 安裝Opencv指令

cd ~/Documents/OpenCV-2.4.9/release
sudo make install

6.跑的結果

第四步~是看檔案有沒有確實安裝

7. 到Xcode6 開啟新檔案 OS X => Application => Command Line Tool => Next

8.隨便取名 ~不過語言記得選C++

9.

10.

11.

Header Search Paths 加入/usr/local/include

12.

Library Search Paths 加入=>/usr/local/lib

13.

程式碼:

#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace std;
using namespace cv;
int main(int argc, char* argv[])
{

     IplImage* img = cvLoadImage("/Users/apple/Documents/blackhole2.jpg"); //圖檔
     cvNamedWindow("Example1",CV_WINDOW_AUTOSIZE);
     cvShowImage("Example1", img);
     cvWaitKey(0);
     cvReleaseImage(&img);
     cvDestroyWindow("Example1");
}

OpenCV contours(輪廓)

OpenCV 在輪廓的應用

參考範例程式碼:

http://docs.opencv.org/doc/tutorials/imgproc/shapedescriptors/find_contours/find_contours.html

利用findContours 跟 drawContours

1.

2.

VS2008 WindowsForm + OpenCV

利用VS2008本身的視窗表單應用在OpenCV

1.

2.

3.因為出現了

error C3862: 'cvRound': 不能以 /clr:pure 或 /clr:safe 編譯 Unmanaged 函式~ 所以加了這一步

要看詳細的話~請參看這個網址:

http://msdn.microsoft.com/zh-tw/library/ms235211%28v=vs.90%29.aspx

4. 在表單上拉元件 ~ 用PictureBox 跟 Button這兩個元件拉

5.拉一個正在關閉的事件

6. 執行結果畫面

程式碼:

#pragma once
#include <cv.h>
#include <highgui.h>

//Global variables
IplImage* src = NULL;
IplImage* hsv = NULL;
IplImage* dst = NULL;
