Brain-inspired robust delineation operator
In this paper we present a novel filter, based on the existing COSFIRE
filter, for the delineation of patterns of interest. It includes a mechanism of
push-pull inhibition that improves robustness to noise in terms of spurious
texture. Push-pull inhibition is a phenomenon that is observed in neurons in
area V1 of the visual cortex, which suppresses the response of certain simple
cells for stimuli of preferred orientation but of non-preferred contrast. This
type of inhibition allows for sharper detection of the patterns of interest and
improves the quality of delineation especially in images with spurious texture.
We performed experiments on images from different applications, namely the
detection of rose stems for automatic gardening, the delineation of cracks in
pavements and road surfaces, and the segmentation of blood vessels in retinal
images. Push-pull inhibition helped to improve results considerably in all
applications.Comment: Accepted at Brain-driven Computer Vision workshop at ECCV 201
