Algorithms for data-driven learning of domain-specific overcomplete dictionaries are developed to obtain maximum likelihood and maximum a posteriori dictionary estimates based on the use of Bayesian models with concave/Schur-concave (CSC) negative log priors. In general such a transformation will not be an affine transformation, so you cannot express this in terms of affine transformations like scaling, rotating and shearing, since these cannot express perspectivity.
