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. * * Member of `Features2d` */ CV_EXPORTS @interface SimpleBlobDetector : Feature2D #ifdef __cplusplus @property(readonly)cv::Ptr nativePtrSimpleBlobDetector; #endif #ifdef __cplusplus - (instancetype)initWithNativePtr:(cv::Ptr)nativePtr; + (instancetype)fromNative:(cv::Ptr)nativePtr; #endif #pragma mark - Methods // // static Ptr_SimpleBlobDetector cv::SimpleBlobDetector::create(SimpleBlobDetector_Params parameters = SimpleBlobDetector::Params()) // + (SimpleBlobDetector*)create:(SimpleBlobDetectorParams*)parameters NS_SWIFT_NAME(create(parameters:)); + (SimpleBlobDetector*)create NS_SWIFT_NAME(create()); // // String cv::SimpleBlobDetector::getDefaultName() // - (NSString*)getDefaultName NS_SWIFT_NAME(getDefaultName()); @end NS_ASSUME_NONNULL_END
