Member Function Documentation

virtual TextureTransformDisplacement* BIAS::TextureTransformDisplacement::Clone ( ) const

virtual covariant copy constructor, caller must eventually destroy the created object

void BIAS::TextureTransformDisplacement::ComposeWithInverseDeltaP ( const Vector< double > & deltaP )

inlinevirtual

concatenate *this and an inverse transform with param deltaP and save new parameter vector to *this.

Apart from very simple transformations like displacement THIS IS NOT A SIMPLE ADDITION but rather a multiplication-like operation!

This function is particularly important for inverse compositional image alignment (KLT)
