Class QuadrilateralTransformation

java.lang.Object

Catalano.Imaging.Tools.QuadrilateralTransformation

All Implemented Interfaces:

IProcessImage

public class QuadrilateralTransformation
extends java.lang.Object
implements IProcessImage

Performs quadrilateral transformation of an area in a given source image. The class implements quadrilateral transformation algorithm, which allows to transform any quadrilateral from a given source image to a rectangular image. The idea of the algorithm is based on homogeneous transformation and its math is described by Paul Heckbert in his "Projective Mappings for Image Warping" paper.
