Struct opencv::line_descriptor::BinaryDescriptor

pub struct BinaryDescriptor { /* private fields */ }

Class implements both functionalities for detection of lines and computation of their binary descriptor.

Class’ interface is mainly based on the ones of classical detectors and extractors, such as Feature2d’s [features2d_main] and [features2d_match]. Retrieved information about lines is stored in line_descriptor::KeyLine objects.

Implementations

impl BinaryDescriptor

pub fn new(parameters: &BinaryDescriptor_Params) -> Result<BinaryDescriptor>

Constructor

Parameters

• parameters: configuration parameters BinaryDescriptor::Params

If no argument is provided, constructor sets default values (see comments in the code snippet in previous section). Default values are strongly recommended.

C++ default parameters

• parameters: BinaryDescriptor::Params()

pub fn create_binary_descriptor() -> Result<Ptr<BinaryDescriptor>>

Create a BinaryDescriptor object with default parameters (or with the ones provided) and return a smart pointer to it

pub fn create_binary_descriptor_1( parameters: BinaryDescriptor_Params ) -> Result<Ptr<BinaryDescriptor>>

Trait Implementations

impl AlgorithmTrait for BinaryDescriptor

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 BinaryDescriptor

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.
