Title: 
"Orientational minimal redundancy wavelets: from edge detection to
perception" 

Authors:
Antonio Turiel, Jean-Pierre Nadal and Nestor Parga

Abstract:

Natural images are complex but very structured objects and, in spite of 
their complexity, the sensory areas in the neocortex of mammals are able
to devise learned strategies to encode them efficiently. How is this goal
achieved? In this paper, we will discuss the multiscaling approach, which
has been recently used to derive a redundancy reducing wavelet basis. This
kind of representation can be statistically learned from the data and is
optimally adapted for image coding; besides, it presents some remarkable
features found in the visual pathway. We will show that the introduction
of oriented wavelets is necessary to provide a complete description, which
stresses the role of the wavelets as edge detectors.
