Struct opencv::xfeatures2d::HarrisLaplaceFeatureDetector

pub struct HarrisLaplaceFeatureDetector { /* fields omitted */ }

Class implementing the Harris-Laplace feature detector as described in Mikolajczyk2004.

Methods

impl HarrisLaplaceFeatureDetector

pub fn as_raw_HarrisLaplaceFeatureDetector(&self) -> *mut c_void

pub unsafe fn from_raw_ptr(ptr: *mut c_void) -> Self

impl HarrisLaplaceFeatureDetector

pub fn create(
    num_octaves: i32,
    corn_thresh: f32,
    dog_thresh: f32,
    max_corners: i32,
    num_layers: i32
) -> Result<PtrOfHarrisLaplaceFeatureDetector>

Creates a new implementation instance.

Parameters

• numOctaves: the number of octaves in the scale-space pyramid
• corn_thresh: the threshold for the Harris cornerness measure
• DOG_thresh: the threshold for the Difference-of-Gaussians scale selection
• maxCorners: the maximum number of corners to consider
• num_layers: the number of intermediate scales per octave

C++ default parameters

• num_octaves: 6
• corn_thresh: 0.01f
• dog_thresh: 0.01f
• max_corners: 5000
• num_layers: 4

Trait Implementations

impl AlgorithmTrait for HarrisLaplaceFeatureDetector

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.

impl Drop for HarrisLaplaceFeatureDetector

fn drop(&mut self)

Executes the destructor for this type.
