Trait Implementations

impl AlgorithmTrait for PtrOfAgastFeatureDetector

fn as_raw_Algorithm(&self) -> *mut c_void

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn write(&self, fs: &mut FileStorage) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &PtrOfFileStorage, name: &str) -> Result<()>

simplified API for language bindings

fn read(&mut self, _fn: &FileNode) -> Result<()>

Reads algorithm parameters from a file storage

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

fn set_threshold(&mut self, threshold: i32) -> Result<()>

fn get_threshold(&self) -> Result<i32>

fn set_nonmax_suppression(&mut self, f: bool) -> Result<()>

fn get_nonmax_suppression(&self) -> Result<bool>

fn set_type(&mut self, _type: i32) -> Result<()>

fn get_type(&self) -> Result<i32>

fn get_default_name(&self) -> Result<String>

impl Feature2DTrait for PtrOfAgastFeatureDetector

fn as_raw_Feature2D(&self) -> *mut c_void

fn detect(
    &mut self,
    image: &dyn ToInputArray,
    keypoints: &mut VectorOfKeyPoint,
    mask: &dyn ToInputArray
) -> Result<()>

Detects keypoints in an image (first variant) or image set (second variant).

fn detect_multiple(
    &mut self,
    images: &dyn ToInputArray,
    keypoints: &mut VectorOfVectorOfKeyPoint,
    masks: &dyn ToInputArray
) -> Result<()>

Parameters * images: Image set. * keypoints: The detected keypoints. In the second variant of the method keypoints[i] is a set of keypoints detected in images[i] . * masks: Masks for each input image specifying where to look for keypoints (optional). masks[i] is a mask for images[i].

fn compute(
    &mut self,
    image: &dyn ToInputArray,
    keypoints: &mut VectorOfKeyPoint,
    descriptors: &mut dyn ToOutputArray
) -> Result<()>

Computes the descriptors for a set of keypoints detected in an image (first variant) or image set (second variant).

fn compute_multiple(
    &mut self,
    images: &dyn ToInputArray,
    keypoints: &mut VectorOfVectorOfKeyPoint,
    descriptors: &mut dyn ToOutputArray
) -> Result<()>

Parameters * images: Image set. * keypoints: Input collection of keypoints. Keypoints for which a descriptor cannot be computed are removed. Sometimes new keypoints can be added, for example: SIFT duplicates keypoint with several dominant orientations (for each orientation). * descriptors: Computed descriptors. In the second variant of the method descriptors[i] are descriptors computed for a keypoints[i]. Row j is the keypoints (or keypoints[i]) is the descriptor for keypoint j-th keypoint.

fn detect_and_compute(
    &mut self,
    image: &dyn ToInputArray,
    mask: &dyn ToInputArray,
    keypoints: &mut VectorOfKeyPoint,
    descriptors: &mut dyn ToOutputArray,
    use_provided_keypoints: bool
) -> Result<()>

Detects keypoints and computes the descriptors

fn read(&mut self, file_name: &str) -> Result<()>

fn write_1(&self, unnamed_arg: &mut FileStorage) -> Result<()>

fn read_1(&mut self, unnamed_arg: &FileNode) -> Result<()>

fn empty(&self) -> Result<bool>

Return true if detector object is empty
