Trait Implementations

impl Algorithm for PtrOfFastFeatureDetector

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

Clears the algorithm state

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.

impl Feature2D for PtrOfFastFeatureDetector

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

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

fn detect_n(
    &mut self,
    images: &VectorOfMat,
    keypoints: &VectorOfVectorOfKeyPoint,
    masks: &VectorOfMat
) -> Result<()>

@overload ## 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: &Mat,
    keypoints: &VectorOfKeyPoint,
    descriptors: &mut Mat
) -> Result<()>

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

fn compute_1(
    &mut self,
    images: &VectorOfMat,
    keypoints: &VectorOfVectorOfKeyPoint,
    descriptors: &mut VectorOfMat
) -> Result<()>

@overload

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

Detects keypoints and computes the descriptors

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

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

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

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

impl Drop for PtrOfFastFeatureDetector

fn drop(&mut self)

Executes the destructor for this type.
