The content introduces a novel approach to image processing using the sub-Riemannian structure inspired by the visual cortex V1. It presents algorithms for image inpainting and enhancement, focusing on preventing fading and producing sharper results through a procedure called WaxOn-WaxOff. The use of sub-Riemannian geometry allows for the definition of a new unsharp filter analogous to classical 2D image processing filters. The method is demonstrated on enhancing blood vessels in retinal scans. The article also discusses related works in the field of Lie Group SE(2) relative to image processing, particularly in retinal imagery.
