mx::improc::cubicConvolTransform< _arithT > Struct Template Reference

template<typename _arithT>
struct mx::improc::cubicConvolTransform< _arithT >

Transformation by cubic convolution interpolation.

Uses the cubic convolution interpolation kernel. See https://en.wikipedia.org/wiki/Bicubic_interpolation .

The parameter cubic should be left as the default -0.5 in most cases, which gives the bicubic spline interpolator. See https://en.wikipedia.org/wiki/Cubic_Hermite_spline.

Template Parameters

_arithT

is the type in which to do all calculations. Should be a floating point type.

Test:

Scenario: Verify direction and accuracy of various image shifts [test doc]
