示例1: HoughLines
import org.opencv.imgproc.Imgproc; //導入方法依賴的package包/類
void HoughLines() {
Mat grayMat = new Mat();
Mat cannyEdges = new Mat();
Mat lines = new Mat();
//Converting the image to grayscale
Imgproc.cvtColor(originalMat, grayMat, Imgproc.COLOR_BGR2GRAY);
Imgproc.Canny(grayMat, cannyEdges, 10, 100);
Imgproc.HoughLinesP(cannyEdges, lines, 1, Math.PI / 180, 50, 20, 20);
Mat houghLines = new Mat();
houghLines.create(cannyEdges.rows(), cannyEdges.cols(), CvType.CV_8UC1);
//Drawing lines on the image
for (int i = 0; i < lines.cols(); i++) {
double[] points = lines.get(0, i);
double x1, y1, x2, y2;
x1 = points[0];
y1 = points[1];
x2 = points[2];
y2 = points[3];
Point pt1 = new Point(x1, y1);
Point pt2 = new Point(x2, y2);
//Drawing lines on an image
Imgproc.line(houghLines, pt1, pt2, new Scalar(255, 0, 0), 1);
}
//Converting Mat back to Bitmap
Utils.matToBitmap(houghLines, currentBitmap);
imageView.setImageBitmap(currentBitmap);
}
示例2: HoughLines
import org.opencv.imgproc.Imgproc; //導入方法依賴的package包/類

Mat cannyEdges = new Mat();
Mat lines = new Mat();
Imgproc.cvtColor(image, grayMat, Imgproc.COLOR_RGB2GRAY);
Imgproc.Canny(grayMat, cannyEdges, 10, 100);
Imgproc.HoughLinesP(cannyEdges, lines, 1, Math.PI/180, 50,20,20);
return lines;
