Struct opencv::xfeatures2d::BriefDescriptorExtractor

pub struct BriefDescriptorExtractor { /* fields omitted */ }

Class for computing BRIEF descriptors described in calon2010 .

Parameters

• bytes: legth of the descriptor in bytes, valid values are: 16, 32 (default) or 64 .
• use_orientation: sample patterns using keypoints orientation, disabled by default.

Methods

impl BriefDescriptorExtractor

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

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

impl BriefDescriptorExtractor

pub fn create(
    bytes: i32,
    use_orientation: bool
) -> Result<PtrOfBriefDescriptorExtractor>

C++ default parameters

• bytes: 32
• use_orientation: false

Trait Implementations

impl AlgorithmTrait for BriefDescriptorExtractor

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 BriefDescriptorExtractor

fn drop(&mut self)

Executes the destructor for this type.
