JAVACV实现人脸识别代码

使用JAVACV实现人脸识别的代码如下： // Load the OpenCV library System.loadLibrary(Core.NATIVE_LIBRARY_NAME); // Create a new CascadeClassifier object with the trained classifier CascadeClassifier faceDetector = new CascadeClassifier("haarcascade_frontalface_alt.xml"); // Create a Mat object to store the image Mat image = Imgcodecs.imread("image.jpg"); // Detect faces in the image using detectMultiScale() method and store it in an array of Rect objects Rect[] facesArray = faceDetector.detectMultiScale(image); // Iterate through each detected face and draw a rectangle around it for (Rect rect : facesArray) { Imgproc.rectangle(image, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect .height), new Scalar(0, 0, 255)); } // Save the image with the detected faces Imgcodecs .imwrite("imageWithFaces .jpg", image);
