Struct opencv::features2d::DescriptorMatcher

pub struct DescriptorMatcher { /* private fields */ }

Abstract base class for matching keypoint descriptors.

It has two groups of match methods: for matching descriptors of an image with another image or with an image set.

Implementations

impl DescriptorMatcher

pub fn create(descriptor_matcher_type: &str) -> Result<Ptr<DescriptorMatcher>>

Creates a descriptor matcher of a given type with the default parameters (using default constructor).

Parameters

• descriptorMatcherType: Descriptor matcher type. Now the following matcher types are supported:
• BruteForce (it uses L2 )
• BruteForce-L1
• BruteForce-Hamming
• BruteForce-Hamming(2)
• FlannBased

pub fn create_with_matcher_type( matcher_type: DescriptorMatcher_MatcherType ) -> Result<Ptr<DescriptorMatcher>>

Trait Implementations

impl AlgorithmTrait for DescriptorMatcher

fn as_raw_mut_Algorithm(&mut self) -> *mut c_void

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

Clears the algorithm state

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

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for DescriptorMatcher

fn as_raw_Algorithm(&self) -> *const c_void

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

Stores algorithm parameters in a file storage

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

Stores algorithm parameters in a file storage

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

@deprecated

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 Boxed for DescriptorMatcher

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

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void
