Hello,
I am realizing an Android application. I have used face-detection samples given my OpenCV to create a face tracking application.
In my Mat tmp, I want to save the inputFrame without red rectangles around faces. If I'm testing the code below on a device, where I return tmp and add rectangles around faces only in rgb, I received though an image where faces are detected (red rectangles). Can someone explain me why I don't receive only the frame delivering by the camera?
@Override
public Mat onCameraFrame(CvCameraViewFrame inputFrame){
gray = inputFrame.gray();
rgb = inputFrame.rgba();
tmp=inputFrame.rgba();
int height = gray.rows();
if (height > 0){
absoluteFaceSize = Math.round(height * relativeFaceSize);
classifierFace.detectMultiScale(gray, faceDetections, 1.1, 3, 2, new Size(absoluteFaceSize,absoluteFaceSize), new Size());
for (Rect rect : faceDetections.toArray())
Core.rectangle(rgb, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect.height), new Scalar(255,0,0), 5);
return tmp;
}
Charlotte.
