Member Function Documentation

applyTransformation()

float cv::ShapeTransformer::applyTransformation(
InputArray input,
OutputArray output = noArray() )

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

Parameters

• input — Contour (set of points) to apply the transformation.

• output — Output contour.

Here is the call graph for this function:

estimateTransformation()

void cv::ShapeTransformer::estimateTransformation(
InputArray transformingShape,
InputArray targetShape,
std::vector< DMatch > & matches )

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.

warpImage()

void cv::ShapeTransformer::warpImage(
InputArray transformingImage,
OutputArray output,
int flags = INTER_LINEAR,
int borderMode = BORDER_CONSTANT,
const Scalar & borderValue = Scalar() )

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.
