Why Do Cells Compete? (UMAP)
Author: Stephan Grossberg
This unit introduces current data about brightness constancy and contrast in visual perception, and shows that data of this kind are a consequence of a principle that holds in all cellular systems. Variations of this principle imply other visual properties, such as edge detection, spatial frequency detection, and pattern-matching properties.
