Required Methods

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

Provided Methods

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.

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()
