A model for end-stopping that requires only excitatory inputs is presented. This model is based on multiplication of the outputs from two orientation tuned and spatial-frequency selective neurons. Computer simulations show that, provided the optimal orientations of the two neurons are sufficiently different, the resulting product will display orientation-independent end-stopping. Neurons simulated in this manner display the main characteristics of actual hypercomplex cells.
