Trait Implementations

impl AlgorithmTrait for PtrOfShapeContextDistanceExtractor

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 PtrOfShapeContextDistanceExtractor

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 ShapeContextDistanceExtractor for PtrOfShapeContextDistanceExtractor

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

fn set_angular_bins(&mut self, n_angular_bins: i32) -> Result<()>

Establish the number of angular bins for the Shape Context Descriptor used in the shape matching pipeline.

fn set_radial_bins(&mut self, n_radial_bins: i32) -> Result<()>

Establish the number of radial bins for the Shape Context Descriptor used in the shape matching pipeline.

fn set_inner_radius(&mut self, inner_radius: f32) -> Result<()>

Set the inner radius of the shape context descriptor.

fn set_outer_radius(&mut self, outer_radius: f32) -> Result<()>

Set the outer radius of the shape context descriptor.

fn set_rotation_invariant(&mut self, rotation_invariant: bool) -> Result<()>

fn set_shape_context_weight(&mut self, shape_context_weight: f32) -> Result<()>

Set the weight of the shape context distance in the final value of the shape distance. The shape context distance between two shapes is defined as the symmetric sum of shape context matching costs over best matching points. The final value of the shape distance is a user-defined linear combination of the shape context distance, an image appearance distance, and a bending energy.

fn set_image_appearance_weight(
    &mut self,
    image_appearance_weight: f32
) -> Result<()>

Set the weight of the Image Appearance cost in the final value of the shape distance. The image appearance cost is defined as the sum of squared brightness differences in Gaussian windows around corresponding image points. The final value of the shape distance is a user-defined linear combination of the shape context distance, an image appearance distance, and a bending energy. If this value is set to a number different from 0, is mandatory to set the images that correspond to each shape.

fn set_bending_energy_weight(
    &mut self,
    bending_energy_weight: f32
) -> Result<()>

Set the weight of the Bending Energy in the final value of the shape distance. The bending energy definition depends on what transformation is being used to align the shapes. The final value of the shape distance is a user-defined linear combination of the shape context distance, an image appearance distance, and a bending energy.

fn set_images(
    &mut self,
    image1: &dyn ToInputArray,
    image2: &dyn ToInputArray
) -> Result<()>

Set the images that correspond to each shape. This images are used in the calculation of the Image Appearance cost.

fn set_iterations(&mut self, iterations: i32) -> Result<()>

fn set_cost_extractor(
    &mut self,
    comparer: Ptr<dyn HistogramCostExtractor>
) -> Result<()>

Set the algorithm used for building the shape context descriptor cost matrix.

fn set_std_dev(&mut self, sigma: f32) -> Result<()>

Set the value of the standard deviation for the Gaussian window for the image appearance cost.

fn set_transform_algorithm(
    &mut self,
    transformer: Ptr<dyn ShapeTransformer>
) -> Result<()>

Set the algorithm used for aligning the shapes.
