/**
 * Class for extracting blobs from an image. :
 *
 * The class implements a simple algorithm for extracting blobs from an image:
 *
 * 1.  Convert the source image to binary images by applying thresholding with several thresholds from
 *     minThreshold (inclusive) to maxThreshold (exclusive) with distance thresholdStep between
 *     neighboring thresholds.
 * 2.  Extract connected components from every binary image by findContours and calculate their
 *     centers.
 * 3.  Group centers from several binary images by their coordinates. Close centers form one group that
 *     corresponds to one blob, which is controlled by the minDistBetweenBlobs parameter.
 * 4.  From the groups, estimate final centers of blobs and their radiuses and return as locations and
 *     sizes of keypoints.
 *
 * This class performs several filtrations of returned blobs. You should set filterBy\* to true/false
 * to turn on/off corresponding filtration. Available filtrations:
 *
 * 
    *
  • * By color. This filter compares the intensity of a binary image at the center of a blob to * blobColor. If they differ, the blob is filtered out. Use blobColor = 0 to extract dark blobs * and blobColor = 255 to extract light blobs. *
  • *
  • * By area. Extracted blobs have an area between minArea (inclusive) and maxArea (exclusive). *
  • *
  • * By circularity. Extracted blobs have circularity * (\(\frac{4*\pi*Area}{perimeter * perimeter}\)) between minCircularity (inclusive) and * maxCircularity (exclusive). *
  • *
  • * By ratio of the minimum inertia to maximum inertia. Extracted blobs have this ratio * between minInertiaRatio (inclusive) and maxInertiaRatio (exclusive). *
  • *
  • * By convexity. Extracted blobs have convexity (area / area of blob convex hull) between * minConvexity (inclusive) and maxConvexity (exclusive). *
  • *
* * Default values of parameters are tuned to extract dark circular blobs. */ public class SimpleBlobDetector extends Feature2D { protected SimpleBlobDetector(long addr) { super(addr); } // internal usage only public static SimpleBlobDetector __fromPtr__(long addr) { return new SimpleBlobDetector(addr); } // // C++: static Ptr_SimpleBlobDetector cv::SimpleBlobDetector::create(SimpleBlobDetector_Params parameters = SimpleBlobDetector::Params()) // public static SimpleBlobDetector create() { return SimpleBlobDetector.__fromPtr__(create_0()); } // // C++: String cv::SimpleBlobDetector::getDefaultName() // public String getDefaultName() { return getDefaultName_0(nativeObj); } @Override protected void finalize() throws Throwable { delete(nativeObj); } // C++: static Ptr_SimpleBlobDetector cv::SimpleBlobDetector::create(SimpleBlobDetector_Params parameters = SimpleBlobDetector::Params()) private static native long create_0(); // C++: String cv::SimpleBlobDetector::getDefaultName() private static native String getDefaultName_0(long nativeObj); // native support for java finalize() private static native void delete(long nativeObj); }
