Provided methods

fn estimate_transformation(
    &mut self,
    transforming_shape: &dyn ToInputArray,
    target_shape: &dyn ToInputArray,
    matches: &mut VectorOfDMatch
) -> 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.

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()

fn warp_image(
    &self,
    transforming_image: &dyn ToInputArray,
    output: &mut dyn ToOutputArray,
    flags: i32,
    border_mode: i32,
    border_value: Scalar
) -> Result<()>

Apply a transformation, given a pre-estimated transformation parameters, to an Image.

Parameters

  • transformingImage: Input image.
  • output: Output image.
  • flags: Image interpolation method.
  • borderMode: border style.
  • borderValue: border value.

C++ default parameters

  • flags: INTER_LINEAR
  • border_mode: BORDER_CONSTANT
  • border_value: Scalar()
