@Khurram Shehzad
have you sorted out the vs2010 configuration of openCV2.3.1, if not, I would like to post a tutorial about that topic, for your convenience.

Cheers

@Khurram
my visual studio is 2008 version, so, I am afraid, no simple answer could be given. But it should be similar as vs 2008 in configuring libraries, head files and other resources.
Keep moving, Cheers

Thanks Andol…….
I’hv got your point and also searched for the solution……….
But now i m stuck at another point……….

In Visual Studio 2010 i couldn’t find the proper Stuff to modify under visual c++ directories category??………….

@Khurram
Hi Khurram, the .exe file extraction is a normal part of installation, through which the installation file unzips rough files into a folder as you specify. In the folder a number of .cmake files can be compiled.

Hy everyone
I am facing an issue that although it seems to b out of the above discussion but don’t mind as i m a beginner in DIGITAL IMAGE PROCESSING…….
The issue is that “Whenever i try to install openCV 2.2.0 it asks be where to extract the files instead of initializing the Setup…..”
Can anybody plz tell me what’s Wrong???????

Andol I am doing a fingertip detection project using opencv , I am trying to use cvConvexHull2 and cvConvexityDefects , but It is not working , can you please get me source code of finger detection . I just badly need it. Please help me.

hi again Ando, i managed to find the hand and draw a box around it thanx to you, now i want to control the mouse by setting its coordinates to say the center of the box. do u have any idea on how to go about it? just to get the x,y coordinates of the mouse and change them. Thank you so much

thank you Ando, will do that..I really needed guidance on this one. Hope i will figure it all out today and have a working version by tonight. cheers

@Onty as method shown in this post, the main function is such like: CvSeq* cvConvexityDefects(const CvArr* contour, const CvArr* convexhull, CvMemStorage* storage=NULL) This method finds all convexities of input contours, in other words, if you input hand contours as the picture shows, you will be returned sequences of convexity structures, via which you can tell how many fingers are detected. More information can be referred here: http://opencv.willowgarage.com/documentation/structural_analysis_and_shape_descriptors.html?highlight=cvconvexitydefect#cvConvexityDefects

hello Ando, if u were to summarise how to do hand gesture recognition, how do u think i should approach it? i am doing a project on that and i know how to find contours, please direct me what to do next.

Hello Junaid, you could refer here: openCV group as a discussing group in Yahoo!, have a look, i believe there are huge documents for both new and experienced.

Hi Andol,
I am a beginner in openCV, what should i learn in openCV to make interactive programs for my projects.

thank you

hi will you tell briefly how to detect the gesture of hands to perform action from it

Thanks Deb. i am not doing such project currently, but my colleague is doing that kind stuff.

Hi!
In hurry I did some spelling mistakes in the reply…Whatever leave it. I want to know; have you done any project for hand gesture matching in OpenCV?

By: Deb

Deb — Wed, 16 Dec 2009 18:33:08 +0000

Hi!
First of all congrates for doing such wonderful an motivating works. May be you are so havituated to all those, bu for me you are a rock-star. Presently I am involved in a project of “Controlling Robot Motion by Hand Gesture”, and your suggestions are really proving helpful to me. Keep doing good jobs.

Thanks,
Deb, India
