I need a Java code with blob detection using parameters (example filterByCircularity). I found several examples in C ++ and Python, but none in Java with OpenCV. I have the code below and need to implement the parameters of blobs detection, (example filterByCircularity). Someone has already implemented this?
Mat orig = Highgui.imread("E:\\PhotoIn.jpg",Highgui.IMREAD_GRAYSCALE);
Mat MatOut= new Mat();
FeatureDetector blobDetector;
blobDetector = FeatureDetector.create(FeatureDetector.SIFT);
MatOfKeyPoint keypoints1 = new MatOfKeyPoint();
blobDetector.detect(orig,keypoints1);
org.opencv.core.Scalar cores = new org.opencv.core.Scalar(0,0,255);
org.opencv.features2d.Features2d.drawKeypoints(orig,keypoints1,MatOut,cores,2);
Highgui.imwrite("e:\\PhotoOut.jpg", MatOut);
