Viste le numerose richieste di informazioni ho realizzato un tutorial in
italiano per l'installazione di OpenCV 2.0 in ambiente Visual Studio.

Il tutorial  disponibile sul mio sito:
http://www.robot-home.it/Software/tutorial_OpenCV_2_VS.php

Chi fosse interessato pu farmi sapere se lo ritiene completo o se  utilee
specificare meglio qualche passaggio?

Grazie

Hi,

I'm new to openCV and I would like to display input from my camera.To do that I
use this code:

--------------------------------------------------------------------
#include "highgui.h"

int main( int argc, char** argv ) {
cvNamedWindow( "Example2", CV_WINDOW_AUTOSIZE );

CvCapture* capture = cvCreateCameraCapture(0) ;
IplImage* frame;


while(1) {
frame = cvQueryFrame( capture );
if( !frame ) break;

cvShowImage( "Example2", frame );
char c = cvWaitKey(33);
if( c == 27 ) break;

}
cvReleaseCapture( &capture );
cvDestroyWindow( "Example2" );
}
--------------------------------------------------------------------

I named it to test.c and compiled it using:

$ g++ test.c -o test -lhighgui

There are no compilation errors but I couldn't see any window or output from my
camera when I run it. Does anyone know why I couldn't get the desired output?


Here are some information from my laptop:

When i debug this code it will not work again, as there is only a glisp of

How could I use this code?

Hey guys, I'm successfully finding the corners of the chessboard using the
findChessboardCorners(...) function, and then passing the corners I get from
that to the drawChessboardCorners(...) function, but no corners are being drawn.
I know they are computing correctly by looking at the coordinates. So it seems
that drawChessboardCorners(...) is not doing its job. Here is the wiki reference
to this function: http://bit.ly/6LgYNX

I'd suggest you email the authors. If for some reason they don't send you a
link, you can write a simple app to replace each pure red (or whatever color the
markings are) pixel with an interpolated value from its 4 or 8 neighbors.

Hi,
Im working on a part of a program to identify corners of a table top, and warp
these points into the correct perspective. I have managed to do this and from
here Id like to do two things: the first is to get an inverse perspective warp
matrix and the second is to transform single points using the warp matrix from
getPerspectiveTransform as well as transform points using the inverse warp
matrix.

To find the inverse do I use cvInvert to find the inverse or is there a way to
use getPerspectiveTransform directly?
For the second task of transforming single points im not sure what to use. Any
help is greatly appreciated!

I realize this question is likely answered already, but I did a bit of searching
and didnt find, but I apologize if I missed a post regarding this already.

thank you and Happy New Year

Subject: Patch: solve() in cxcore/cxlapack.cpp does double the work for small matrices
stippling_org
Offline Offline
Send Email Send Email
 
Hi:

cvSolve() calls solve() in cxcore/cxlapack.cpp, which has special cases for
small (2x2 and 3x3) systems of equations.  For these special cases it uses
hand-written solutions instead of calling the heavy-weight Lapack machinery,
which is great.

Unfortunately a typo in the code prevents solve() from returning after the
special cases.  Instead, execution continues on to the Lapack machinery, which
solves the systems all over again.  This is, of course, slow.

I have included the trivial patch to fix this bug in this post -- could someone
apply it to the current SVN?  I can't for the life of me figure out how to get
to the OpenCV bug repository on the ROS pages.

I have tested this in my applications, but not with the OpenCV test suite.

If you're curious, it seems that the bug was introduced in Jan 2009 with
revision 1550 where a macro called EXIT was removed, hence removing the early
return.

Thanks,

Adrian Secord.

That's probably because you are not using the same compiler for Qt and
OpenCV. Use the same compiler to compile both. Failing that, disabling
SSE in OpenCV should work

// It works (with scale = 1 of course);

- cvImage is an IplImage with its buffer shared with a QImage like this:

IplImage* frame = cvQueryFrame(mCamera);
QImage qtImage = QImage(QSize(frame->width,  frame->height),
QImage::Format_RGB888);
cvImage = cvCreateImageHeader(cvSize(frame->width, frame->height),  8,
3);
cvImage->imageData = (char *)qtImage.bits();

Currently I'm familiarising myself with VS2008 and so far I'm able to load an

I would like to know how to capture images from network cameras and display them

connected to the internet. They have static IP addresses of
"http://192.168.2.30" and "http://192.168.2.31" respectively. Both of their
usernames are "admin" and passwords are blank.

Any help is appreciated. Sample codes would be good too. Thanks :)

Razerjack,

Your problem is that you do not understand C/C++ pointers.

Go read Chapter 5 of Kernighan & Ritchie:

Alternatively, the following web site is very helpful:

hi ,


currentBlob =blobs.GetBlob(i);

error C2440: '=' : cannot convert from 'CBlob' to 'CBlob *'

I am having this error . i tried to do different things to remove this but :(


then I tried currentBlob=(CBlob*)blobs.GetBlob(i);

error C2440: 'type cast' : cannot convert from 'CBlob' to 'CBlob *'

Thanx in advance

Hello everyone,

I have a problem in using the library "cvblobslib" in CodeGear C++Builder2009

As usual, I used Coff2Omf to get compatible LIB file to CodeGear C++Builder.
Then I included all the necessary paths and directories to my project. And I
also added the cvbloblibs.lib to the project.

After doing the previous settings, I get the following linker error:

[ILINK32 Error] Error: Unresolved external 'CBlobResult::~CBlobResult()'
referenced from C:\DOCUMENTS AND SETTINGS\PROJECTS\BLOBS\DEBUG\UNIT1.OBJ

[ILINK32 Error] Error: Unresolved external 'CBlobResult::CBlobResult()'
referenced from C:\DOCUMENTS AND SETTINGS\PROJECTS\BLOBS\DEBUG\UNIT1.OBJ

Could you please help me! You can download the library and do test to see the
problem.

The download link:
http://opencv.willowgarage.com/wiki/cvBlobsLib?action=AttachFile&do=view&target=\
cvblobslib_OpenCV_v8_3.zip

I am looking forward to hearing your help.

Merry Christmas!

Regards,

hi

which file to add to pkg_config_path to enable xine in ./configure??
xine is installed but pkg-config --libs xine is failing to find out xine.pc.

hi


But i found

[root@rac-1 OpenCV-2.0.0]# pkg-config --libs ffmpeg
Package ffmpeg was not found in the pkg-config search path.
Perhaps you should add the directory containing `ffmpeg.pc'
to the PKG_CONFIG_PATH environment variable
No package 'ffmpeg' found
[root@rac-1 OpenCV-2.0.0]#

how to add ffmpeg to package config path?
