i hope initially coefficients are in 8 bit,

first multiply each coefficients with 2048, before any processing and convert them to an integer, then do your processing after that divide each process data by 2048.

how to set environment variable path on ubuntu 12.04 lts for OpenCV based application like image display or video play.

----------------------------------------------------- my sample code--------

include "stdio.h"

include "/home/kaushal/OpenCV/opencv-2.4.7/include/highgui.h"

int main( int argc, char** argv )

{ IplImage* img = 0; if( argc < 2 ) {printf( "Usage: Accepts one image as argument\n" ); exit( EXIT_SUCCESS );

}

img = cvLoadImage( argv[1] );

if( !img ) { printf( "Error loading image file %s\n", argv[1]); exit( EXIT_SUCCESS );

}

cvNamedWindow( "Example1", CV_WINDOW_AUTOSIZE ) cvMoveWindow( "Example1", 100, 100 ); cvShowImage( "Example1", img ); cvWaitKey( 0 ); cvReleaseImage( &img ); cvDestroyWindow( "Example1" ); return EXIT_SUCCESS;

}

//---------------------and the Output is------------

Hello Friend's

Got the solution.

by doing following changes you will have color video out.

define CH_COLOR 3

IplImage *rgbImage = cvCreateImage(cvSize((int)width, (int)height), IPL_DEPTH_8U, CH_COLOR);
rgbImage->widthStep = (int)width * 3;

Hello Friends,

my maxframeCounter = 100,000;

my ErrCode = CvCaptureQueueFrame((myCamera.handle),&(myCamera.Frame),NULL);

The Return Value of ErrCode = 5;

What is the meaning of this return Value = 5, and what precaution should i take to overcome from this value from the document the return value of ErrCode Supposed to any one from:

  1. ePvErrSucess

2.ePvErrUnplugged

3.ePvErrBadSequence

4.ePvErrQueueFull

From The Document AVT/Prosilica PvAPI Manual

I am able to compile my GigE code along with openCV libraries without any error.

but it ask for PvAPI.dll though i have PvAPI.dll but I just wanted to know where to put "PvAPI.dll",

as each time i run my code it ask about PvAPI.dll saying that

PvAPI.dll is missing from your computer, try reinstalling the program to fixm this problem

if i put this dll in my OpnCV dll's,during run time it says

"The application was unable to start correctly (0XC000007b.)"

As you have suggest, the error is because i am trying to link old version of opencv, now i have remove this file along with other file have "210d.lib", and also configure C/C++ and Linker as mentioned below 1. C/C++ --> Additional Include Directories: "C:\Program Files \Allied Vision Technologies\GigESDK\lib-pc" 2. C/C++ --> Additional Include Directories: "C:\Program Files \Allied Vision Technologies\GigESDK\inc-pc"

3.Linker->Additional Library Directories "C:\Program Files \Allied Vision Technologies\GigESDK\lib-pc" then all error gone and new error come Like:

Error 2 error LNK2005: __initp_misc_invarg already defined in LIBCMTD.lib(invarg.obj) C:\Program Files\Allied Vision Technologies\GigESDK\examples\App5 - Snap O

I have GC2450C Allied Vision Camera and my OS is windows-7, how do i read this GigE Camera Image/Video Through OpenCV.

my OpenCV directory structure show that i have cap_pvapi.cpp file is available (dono what is this but every time i start googling these key word CV_CAP_PVAPI visible on monitor)
