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_: &impl FileNodeTraitConst) -> 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 impl FileStorageTrait) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut impl FileStorageTrait, 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 AlgorithmTraitConst::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: <HausdorffDistanceExtractor as OpenCVFromExtern>::ExternReceive, ) -> Self

Wrap the specified raw pointer

fn into_raw( self, ) -> <HausdorffDistanceExtractor as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw( &self, ) -> <HausdorffDistanceExtractor as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self, ) -> <HausdorffDistanceExtractor as OpenCVTypeExternContainer>::ExternSendMut

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 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.
