Trait Implementations

source

impl AlgorithmTrait for Feature2D

source

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

source

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

Clears the algorithm state

source

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

Reads algorithm parameters from a file storage

source

impl AlgorithmTraitConst for Feature2D

source

fn as_raw_Algorithm(&self) -> *const c_void

source

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

Stores algorithm parameters in a file storage

source

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

simplified API for language bindings Stores algorithm parameters in a file storage Read more

source

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

source

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). Read more

source

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. Read more
