Paper Abstract
Empirical evidence from both psychology and physiology stresses the importance of inherently
two-dimensional signals and corresponding operations in vision. Examples of this are the existence of
"bug-detectors" , hypercomplex and dot-responsive cells, the occurence of contour illusions, and interactions of
patterns with clearly separated orientations. These phenomena can not be described, and have been largely
ignored, by common theories of size and orientation selective channels. The reason for this is shown to be
located at the heart of the theory of linear systems: their one-dimensional eigenfunctions and the "or"-like
character of the superposition principle. Consequently, a nonlinear theory is needed. We present a first
approach towards a general framework for the description of 2D-signals and 2D-cells in biological vision.
