FastFeatureDetector.create({int threshold = 10, bool nonmaxSuppression = true, FastFeatureDetectorType type = FastFeatureDetectorType.TYPE_9_16}): returns a new FastFeatureDetector algorithm with parameters
factory
FastFeatureDetector.empty(): returns a new FastFeatureDetector algorithm
factory
FastFeatureDetector.fromPointer(FastFeatureDetectorPtr ptr, [bool attach = true]): factory

detect(Mat src, {VecKeyPoint? keypoints, Mat? mask}) → VecKeyPoint: Detect keypoints in an image using FastFeatureDetector.
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 FastFeatureDetector, provided by the FastFeatureDetectorAsync extension
DetectAndCompute keypoints and compute in an image using AKAZE.
detectAsync(Mat src, {VecKeyPoint? keypoints, Mat? mask}) → Future<VecKeyPoint>: Available on FastFeatureDetector, provided by the FastFeatureDetectorAsync extension
Detect keypoints in an image using FastFeatureDetector.
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
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
