        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:)

input:

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);



    }
