opencl 2D image interfacing example

This progame is using opencl load image from the host source image and copy to host destination image buffer. It is helpful to understand 2D image interface of opencl.

I used opencv for loading and showing images.

opencl_image_copy_example

install opencv on windows

------------------------------------------------------
opencv officail home
------------------------------------------------------
http://opencv.org/

------------------------------------------------------
download
------------------------------------------------------
http://opencv.org/downloads.html

1. extract donwload opencv package where do you want to install
-  I used opencv 2.4.6
-  My installation DIR is C:\opencv_2.4.6
- I test it under VC10

2. set opencv enviroment variable and add path
- open console then enter below command
 $ setx -m OPENCV_DIR C:\opencv_2.4.6\build\x86\vc10
- add path
%OPENCV_DIR%\bin

3. create sample project in VS

 

4. select property manager(?) tab and right click Debug | Win32 then add new project propery





















5. Type the name then create

 6. right click the create property sheet, then select propery












7. move c/c++  then add additional include directory C:\opencv_2.4.6\build\include
















8. move link, then add additional library directory C:\opencv_2.4.6\build\x86\vc10\lib

















8. move link, input directory then add additional dependency and add below libs

 

opencv_core246d.lib
opencv_imgproc246d.lib
opencv_highgui246d.lib
opencv_ml246d.lib
opencv_video246d.lib
opencv_features2d246d.lib
opencv_calib3d246d.lib
opencv_objdetect246d.lib
opencv_contrib246d.lib
opencv_legacy246d.lib
opencv_flann246d.lib

9 .make main functin as like below

 

#include "stdafx.h"

#include <opencv\cv.h>
#include <opencv\highgui.h>

int _tmain(int argc, _TCHAR* argv[])
{
 IplImage * image = cvLoadImage("C:\\Hydrangeas.jpg", 1);

 cvShowImage("test image", image);
 cvWaitKey(0);

 cvReleaseImage(&image);

 return 0;
}

 

then build and run
