Texture transfer using affine transformation groups and patch boundary matching

An algorithm for performing texture transfer based on an affine transformation model is presented. Image textures are modelled by placing a single patch of texture, a prototype patch, from which the texture is derived using a set of affine transformations. Overlapping target patches covering the entire image are used and a corresponding set of transformations are found to map the prototype patch to these target patches. Texture transfer can be achieved by using different prototype patches. An iterative patch boundary matching algorithm is then applied to minimise the discontinuities between adjacent patches. Illustrative results of the affine texture model and its use in texture synthesis and texture transfer are given.
