示例1: sharpenImage
import org.opencv.core.Core; //导入方法依赖的package包/类
public void sharpenImage() {
String fileName = "SharpnessExample2.png";
fileName = "smoothCat.jpg";
fileName = "blurredText.jpg";
fileName = "Blurred Text3.jpg";
try {
// Not working that well !!!
Mat source = Imgcodecs.imread(fileName,
// Imgcodecs.CV_LOAD_IMAGE_COLOR);
Imgcodecs.CV_LOAD_IMAGE_GRAYSCALE);
Mat destination = new Mat(source.rows(), source.cols(), source.type());
Imgproc.GaussianBlur(source, destination, new Size(0, 0), 10);
// The following was used witht he cat
// Core.addWeighted(source, 1.5, destination, -0.75, 0, destination);
// Core.addWeighted(source, 2.5, destination, -1.5, 0, destination);
Core.addWeighted(source, 1.5, destination, -0.75, 0, destination);
Imgcodecs.imwrite("sharpenedCat.jpg", destination);
} catch (Exception ex) {
ex.printStackTrace();
}

示例2: Sobel
import org.opencv.core.Core; //导入方法依赖的package包/类
void Sobel() {
Mat grayMat = new Mat();
Mat sobel = new Mat(); //Mat to store the final result
//Matrices to store gradient and absolute gradient respectively
Mat grad_x = new Mat();
Mat abs_grad_x = new Mat();
Mat grad_y = new Mat();
Mat abs_grad_y = new Mat();
//Converting the image to grayscale
Imgproc.cvtColor(originalMat, grayMat, Imgproc.COLOR_BGR2GRAY);
//Calculating gradient in horizontal direction
Imgproc.Sobel(grayMat, grad_x, CvType.CV_16S, 1, 0, 3, 1, 0);
//Calculating gradient in vertical direction
Imgproc.Sobel(grayMat, grad_y, CvType.CV_16S, 0, 1, 3, 1, 0);
//Calculating absolute value of gradients in both the direction
Core.convertScaleAbs(grad_x, abs_grad_x);
Core.convertScaleAbs(grad_y, abs_grad_y);
//Calculating the resultant gradient
Core.addWeighted(abs_grad_x, 0.5, abs_grad_y, 0.5, 1, sobel);
//Converting Mat back to Bitmap
Utils.matToBitmap(sobel, currentBitmap);
imageView.setImageBitmap(currentBitmap);
