Trait Implementations

impl AlgorithmTrait for HausdorffDistanceExtractor

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 HausdorffDistanceExtractor

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 write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of [write_with_name] function uses the following default values for its arguments:

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 HausdorffDistanceExtractor

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

impl Debug for HausdorffDistanceExtractor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for HausdorffDistanceExtractor

fn drop(&mut self)

Executes the destructor for this type.

impl From<HausdorffDistanceExtractor> for Algorithm

fn from(s: HausdorffDistanceExtractor) -> Self

Converts to this type from the input type.

impl From<HausdorffDistanceExtractor> for ShapeDistanceExtractor

fn from(s: HausdorffDistanceExtractor) -> Self

Converts to this type from the input type.

impl HausdorffDistanceExtractorTrait for HausdorffDistanceExtractor

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

fn set_distance_flag(&mut self, distance_flag: i32) -> Result<()>

Set the norm used to compute the Hausdorff value between two shapes. It can be L1 or L2 norm.

fn set_rank_proportion(&mut self, rank_proportion: f32) -> Result<()>

This method sets the rank proportion (or fractional value) that establish the Kth ranked value of the partial Hausdorff distance. Experimentally had been shown that 0.6 is a good value to compare shapes.

impl HausdorffDistanceExtractorTraitConst for HausdorffDistanceExtractor

fn as_raw_HausdorffDistanceExtractor(&self) -> *const c_void

fn get_distance_flag(&self) -> Result<i32>

fn get_rank_proportion(&self) -> Result<f32>

impl ShapeDistanceExtractorTrait for HausdorffDistanceExtractor

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

fn compute_distance( &mut self, contour1: &impl ToInputArray, contour2: &impl ToInputArray ) -> Result<f32>

Compute the shape distance between two shapes defined by its contours.

impl ShapeDistanceExtractorTraitConst for HausdorffDistanceExtractor

fn as_raw_ShapeDistanceExtractor(&self) -> *const c_void

impl TryFrom<ShapeDistanceExtractor> for HausdorffDistanceExtractor

type Error = Error

The type returned in the event of a conversion error.

fn try_from(s: ShapeDistanceExtractor) -> Result<Self>

Performs the conversion.
