Expand description

Abstract base class for shape transformation algorithms.

Required Methods§

source

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

Provided Methods§

source

fn estimate_transformation( &mut self, transforming_shape: &dyn ToInputArray, target_shape: &dyn ToInputArray, matches: &mut Vector<DMatch> ) -> Result<()>

Estimate the transformation parameters of the current transformer algorithm, based on point matches.

Parameters
  • transformingShape: Contour defining first shape.
  • targetShape: Contour defining second shape (Target).
  • matches: Standard vector of Matches between points.
source

fn apply_transformation( &mut self, input: &dyn ToInputArray, output: &mut dyn ToOutputArray ) -> Result<f32>

Apply a transformation, given a pre-estimated transformation parameters.

Parameters
  • input: Contour (set of points) to apply the transformation.
  • output: Output contour.
C++ default parameters
  • output: noArray()
