How to setting cropping size in CascadeCalssifier with Java












1














public BufferedImage detectAndDisplay(BufferedImage img, CascadeClassifier faceCascade) {
Mat frameGray = new Mat();
BufferedImage imgout = null;

Mat image = ImagePreProcessing.bufferedImageToMat(img);

// -- Detect faces
MatOfRect faces = new MatOfRect();
faceCascade.detectMultiScale(image, faces);

List<Rect> listOfFaces = faces.toList();
for (Rect face : listOfFaces) {
Point center = new Point(face.x + face.width / 2, face.y + face.height / 2);
Imgproc.ellipse(image, center, new Size(face.width / 2, face.height / 2), 0, 0, 360,
new Scalar(255, 0, 255), 3);

Mat faceROI = image.submat(face);
imgout = ImagePreProcessing.Mat2BufferedImage(faceROI);
System.out.println("OpenCV: " +center);

}
return imgout;
}


that code I have..but I don't know where the code for setting crop output image.
I want to have the picture like original version with circle template..NOT to be crop
Can give me suggestion, please:)

  • Thank you for your attention @BahramdunAdil .I want NOT the picture to be crop. I want the picture still in its size (size_input = size_output)

In your code, you returned a cropped image of the original image, so if you want the original image, draw the circle and convert it to the BufferedImage and return.



for (Rect face : listOfFaces) {
Point center = new Point(face.x + face.width / 2, face.y + face.height / 2);
Imgproc.ellipse(image, center, new Size(face.width / 2, face.height / 2), 0, 0, 360,
new Scalar(255, 0, 255), 3);

// dot not crop!!!
/*Mat faceROI = image.submat(face);
imgout = ImagePreProcessing.Mat2BufferedImage(faceROI);*/

System.out.println("OpenCV: " +center);
imgout = ImagePreProcessing.Mat2BufferedImage(image);

}
