/ / Implementation of the Shape Context descriptor and matching algorithm

proposed by Belongie et al. in "Shape Matching and Object Recognition Using Shape Contexts" (PAMI 2002). This implementation is packaged in a generic scheme, in order to allow you the implementation of the common variations of the original pipeline.

Provided methods

pub fn set_angular_bins(&mut self, n_angular_bins: i32) -> Result<()>[src]

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

Parameters

  • nAngularBins: The number of angular bins in the shape context descriptor.

pub fn get_angular_bins(&self) -> Result<i32>[src]

pub fn set_radial_bins(&mut self, n_radial_bins: i32) -> Result<()>[src]

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

Parameters

  • nRadialBins: The number of radial bins in the shape context descriptor.

pub fn get_radial_bins(&self) -> Result<i32>[src]

pub fn set_inner_radius(&mut self, inner_radius: f32) -> Result<()>[src]

Set the inner radius of the shape context descriptor.

Parameters

  • innerRadius: The value of the inner radius.

pub fn get_inner_radius(&self) -> Result<f32>[src]

pub fn set_outer_radius(&mut self, outer_radius: f32) -> Result<()>[src]

Set the outer radius of the shape context descriptor.

Parameters

  • outerRadius: The value of the outer radius.

pub fn get_outer_radius(&self) -> Result<f32>[src]

pub fn set_rotation_invariant(&mut self, rotation_invariant: bool) -> Result<()>[src]

pub fn get_rotation_invariant(&self) -> Result<bool>[src]

pub fn set_shape_context_weight(
    &mut self,
    shape_context_weight: f32
) -> Result<()>[src]

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.

Parameters

  • shapeContextWeight: The weight of the shape context distance in the final distance value.

pub fn get_shape_context_weight(&self) -> Result<f32>[src]

pub fn set_image_appearance_weight(
    &mut self,
    image_appearance_weight: f32
) -> Result<()>[src]

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.

Parameters

  • imageAppearanceWeight: The weight of the appearance cost in the final distance value.

pub fn get_image_appearance_weight(&self) -> Result<f32>[src]

pub fn set_bending_energy_weight(
    &mut self,
    bending_energy_weight: f32
) -> Result<()>[src]

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.

Parameters

  • bendingEnergyWeight: The weight of the Bending Energy in the final distance value.

pub fn get_bending_energy_weight(&self) -> Result<f32>[src]
