Abstract :
A set of low-level vision treatments inspired from some knowledge of mammalian retino-cortical mechanisms is proposed. The basic idea is to exploit the contrast sensitivity response of the human visual system (HVS) and the multichannel decomposition of the visual signal in the cortex. The scope of this work is limited to nonlinear filtering, contrast enhancement and edge detection but could be extended to other image treatments
