Hand recognition & gesture use Camera and OpenCV

We can follow step to program an application for Hand recognition & gesture use Camera and OpenCV.

Firstly let see follow chart:

 Step1: Face Detect: use Haar Cascades method 

facecad.detectMultiScale(frame_gray, faces, 1.1, 2, 0 | CV_HAAR_SCALE_IMAGE, cv::Size(30, 30));

for (int i = 0; i < faces.size(); i++) //consider the first face

{

cv::Point center(faces[i].x + faces[i].width*0.5, faces[i].y + faces[i].height*0.5);

maxareai = (faces[i].area() > maxarea) ? i : maxareai;

maxarea = (faces[i].area() > maxarea) ? faces[i].area() : maxarea;

ellipse(myframe, center, cv::Size(faces[i].width*0.5, faces[i].height*0.5), 0, 0, 360, cv::Scalar(255, 0, 255), 4, 8, 0);

}

Step2:Get skin color profile and remove face

Step3: Hand recognition
