我在

java中使用opencv 2.4.10检测到图像中的面部

我把我的面部检测代码.

import org.opencv.core.Core;

import org.opencv.core.Mat;

import org.opencv.core.MatOfRect;

import org.opencv.core.Point;

import org.opencv.core.Rect;

import org.opencv.core.Scalar;

import org.opencv.core.Size;

import org.opencv.highgui.Highgui;

import org.opencv.imgproc.Imgproc;

import org.opencv.objdetect.CascadeClassifier;

public class FaceDetector {

public static void main(String[] args)throws Exception {

int x,y,height,width;

System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

System.out.println("\nRunning FaceDetector");

//CascadeClassifier faceDetector = new CascadeClassifier(FaceDetector.class.getResource("haarcascade_frontalface_alt.xml").getPath());

CascadeClassifier faceDetector=new CascadeClassifier();

faceDetector.load("C:/opencv-2.4.10/opencv/sources/data/haarcascades/haarcascade_frontalface_alt.xml");

//System.out.println(""+faceDetector);

// Mat image = Highgui .imread(FaceDetector.class.getResource("D:/shekar.jpg").getPath());

Mat image = Highgui .imread("D:/Eclipse - New Juno/New Juno Projects/detectface/man1.jpg");

MatOfRect faceDetections = new MatOfRect();

faceDetector.detectMultiScale(image, faceDetections);

System.out.println(String.format("Detected %s faces", faceDetections.toArray().length));

for (Rect rect : faceDetections.toArray()) {

Core.rectangle(image, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect.height),

new Scalar(0, 255, 0));

}

String filename = "china.jpg";

System.out.println(String.format("Writing %s", filename));

Highgui.imwrite(filename, image);

}

}

现在我想裁剪检测到的面部并将其保存为opencv java中的新jpg图像.

裁剪代码是

Rect rectCrop = new Rect(x, y, width, height);

Mat image_roi = image(rectCrop);

image_roi.copyTo(cropimage);

imwrite("cropimage.jpg",image_roi);

错误是

方法图像(Rect)未定义FaceDetector类型

对于FaceDetector类型,方法imwrite(String,Mat)是未定义的

请有人帮我解决这个问题.

谢谢
