Computing in Cortical Columns: Information Processing in Visual Cortex
The orientation hypercolumns in the primate primary visual cortex provide a rich framework for structuring early visual computations. We abstract these columns mathematically, and use this abstraction to derive the early visual computations underlying edge and line finding, stereoscopic fusion, and texture and shading analysis. Coherency within the framework further dictates interactions between these computations. Implications for understanding the neurophysiology of early vision are discussed.
