detect(Mat src, {VecKeyPoint? keypoints, Mat? mask}) → VecKeyPoint: Detect keypoints in an image using SimpleBlobDetector.
override
detectAndCompute(Mat src, Mat mask, {VecKeyPoint? keypoints, Mat? descriptors, bool useProvidedKeypoints = false}) → (VecKeyPoint, Mat): override
detectAndComputeAsync(Mat src, Mat mask, {Mat? descriptors, VecKeyPoint? keypoints, bool useProvidedKeypoints = false}) → Future<(VecKeyPoint, Mat)>: Available on SimpleBlobDetector, provided by the SimpleBlobDetectorAsync extension
DetectAndCompute keypoints and compute in an image using AKAZE.
detectAsync(Mat src, {VecKeyPoint? keypoints, Mat? mask}) → Future<VecKeyPoint>: Available on SimpleBlobDetector, provided by the SimpleBlobDetectorAsync extension
Detect keypoints in an image using SimpleBlobDetector.
dispose() → void: Releases the underlying native resources. Idempotent: calling it more than once is safe, but the object must not be used after dispose.
inherited
freeNative() → void: Frees the native resources owned by this object. Subclasses implement the concrete free logic here; callers must use dispose instead.
override
getBlobContours() → VecVecPoint
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
