I have a code which detect face, both eyes and then the pupil of each eyes. Now I want to detect the corners of each eyes by using white color detection. As I am new to opencv could you please guide me that how should I do this and provide me with an android sample code? This is a part of the code which I have:
for (int i = 0; i < facesArray.length; i++){
Rect r = facesArray[i];
Core.rectangle(mGray, r.tl(), r.br(), new Scalar(0, 255, 0, 255), 3);
Core.rectangle(mRgba, r.tl(), r.br(), new Scalar(0, 255, 0, 255), 3);
eyearea = new Rect(r.x +r.width/8,(int)(r.y + (r.height/4.5)),r.width - 2*r.width/8,(int)( r.height/3.0));
Core.rectangle(mRgba,eyearea.tl(),eyearea.br() , new Scalar(255,0, 0, 255), 2);
Rect eyearea_right = new Rect(r.x +r.width/16,(int)(r.y + (r.height/4.5)),(r.width - 2*r.width/16)/2,(int)( r.height/3.0));
Rect eyearea_left = new Rect(r.x +r.width/16 +(r.width - 2*r.width/16)/2,(int)(r.y + (r.height/4.5)),(r.width - 2*r.width/16)/2,(int)( r.height/3.0));
Core.rectangle(mGray,eyearea_left.tl(),eyearea_left.br() , new Scalar(255,0, 0, 255), 2);
Core.rectangle(mRgba,eyearea_right.tl(),eyearea_right.br() , new Scalar(255, 0, 0, 255), 2);
if(learn_frames<5){
//This part detect the pupil of the eyes
teplateR = get_template(mCascadeER,eyearea_right,20);
teplateL = get_template(mCascadeEL,eyearea_left,20);
learn_frames++;
}else{
match_value = match_eye(eyearea_right,teplateR,FdActivity.method);
match_value = match_eye(eyearea_left,teplateL,FdActivity.method);
;
}
Imgproc.resize(mRgba.submat(eyearea_left), mZoomWindow2, mZoomWindow2.size());
Imgproc.resize(mRgba.submat(eyearea_right), mZoomWindow, mZoomWindow.size());
}
