This thesis explores the role of orientation selectivity and contrast gain control with respect to Barlow's normative redundancy reduction hypothesis in simple models of the early visual system. Our general approach uses the fact that-under the goal of redundancy reduction-early vision models are density models on natural images. We identify and develop new classes of probabilistic models for natural image patches that contain these early vision models. We use those classes to quantitatively explore their parameter space around the early vision models statistically and information theoretically with respect to the influence of filter shapes and contrast transforms on redundancy reduction. We identify an optimal contrast gain control transfo...
