Augmented reality to detect hand heart with webcam

Question

Is it possible?

I'm studying and I'd like tips and links to tutorials that can help me.

Thanks!

I just made a similar program using haarcascades with opencv. I'm sure it could easily tied into ARToolKit. Check out my tutorial. http://danielscvtutorials.blogspot.com/p/impress-that-special-someone-with.html

I was able to tie ARToolKit to OpenCv with this code. For some reason ARToolKit wanted to use ARGB instead of BGR or RGBA.

ARUint8 rgbTmp[3];
for(int y=0; y < image_opencv->height; y++) {
    for(int x=0; x < image_opencv->width; x++) {
        rgbTmp[0] = image_opencv->imageData[image_opencv->widthStep * y + x*3]; // B
        rgbTmp[1] = image_opencv->imageData[image_opencv->widthStep * y + x*3 + 1]; // G
        rgbTmp[2] = image_opencv->imageData[image_opencv->widthStep * y + x*3 + 2]; // R
        frame->imageData[frame->widthStep * y + x*4] = 255; // A
        frame->imageData[frame->widthStep * y + x*4 + 1] = rgbTmp[2]; // R
        frame->imageData[frame->widthStep * y + x*4 + 2] = rgbTmp[1]; // G
        frame->imageData[frame->widthStep * y + x*4 + 3] = rgbTmp[0]; // B
    }
}
ARUint8 *arImage = (ARUint8 *)frame->imageData; // This is very fast conversion
