Lecture 2: Geometric Image TransformationsHarvey RhodyChester F. Carlson Center for Imaging ScienceRochester institute of 8, 2005 AbstractGeometric Transformations are widely used for Image registrationand the removal of Geometric distortion. Common applications includeconstruction of mosaics, geographical mapping, stereo and Lecture 2 Spatial Transformations of ImagesA spatial transformation of an Image is a Geometric transformation of theimage coordinate is often necessary to perform a spatial transformation to: Align images that were taken at different times or with different sensors Correct images for lens distortion Correct effects of camera orientation Image morphing or other special effectsDIP Lecture 21 Spatial TransformationIn a spatial transformation each point(x, y)of imageAis mapped to apoint(u, v)in a new coordinate (x, y)v=f2(x, y)Mapping from(x, y)to(u, v)coordinates.
