Struct opencv::ximgproc::ContourFitting

pub struct ContourFitting { /* private fields */ }

Class for ContourFitting algorithms. ContourFitting match two contours and minimizing distance where and are Fourier descriptors of and and s is a scaling factor and is angle rotation and is starting point factor adjustement

Implementations

impl ContourFitting

pub fn new(ctr: i32, fd: i32) -> Result<ContourFitting>

Parameters

• ctr: number of Fourier descriptors equal to number of contour points after resampling.
• fd: Contour defining second shape (Target).

C++ default parameters

• ctr: 1024
• fd: 16

Trait Implementations

impl AlgorithmTrait for ContourFitting

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 ContourFitting

fn as_raw_Algorithm(&self) -> *const c_void

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

Stores algorithm parameters in a file storage

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

simplified API for language bindings Stores algorithm parameters in 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 Boxed for ContourFitting

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

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer
