I tried changing the code below in the hope that when I don't raise my hand or close my hand the screen will show 0. Can you help me. I want to identify by numbers 1 2 3 4 5 and 0 when holding hands. Hope to receive your response as soon as possible. Thank you very much!
code:
char txt[40] = "";
if (con == 0)
{
char txt1[] = "1";
strcat(txt, txt1);
}
else if (con == 0)
{
char txt1[] = "2";
strcat(txt, txt1);
}
else if (con == 2)
{
char txt1[] = "3";
strcat(txt, txt1);
}
else if (con == 3)
{
char txt1[] = "4";
strcat(txt, txt1);
}
else if (con == 4)
{
char txt1[] = "5";
strcat(txt, txt1);
}
else
{
char txt1[] = "0"; // Jarvis can't recognise you
strcat(txt, txt1);

Hello,
I borrowed an Intel Realsense camera from my lecturer and I code a program to stream the RGB video from the camera and I intend to play around with the camera and try to integrate your codes in it. But I have an issue where I am not sure which part should I modify for it to work. Hoping for your suggestion. I think the problem is the feed from my camera is in Mat Image. Below I attach my code hoping for your reply.

Hi my friend, I've done all the steps according to 'how_to_compile' notes, when i compile it there is no error, but when i run it the webcam doesn't appear. and then the close program window appears. can you help me?
I even change 0 to 1 or -1 but same result...:(
CvCapture* capture = cvCaptureFromCAM(1);
I've also removed '!' from if(!cvQueryFrame(capture)). but same issue

I'm trying to run your code, but :

defects= cvConvexityDefects(ptseq,hull,storage2 );

always return 0, can you help me?
