Top left Café Wall pattern with 200 × 200 px tiles and 8 px mortar. Top right Enlarged DoG output at scale 8 (\( \sigma_{c} = 8 \)) in the edge map. Centre The binary edge map at six different scales (\( \sigma_{c} = 4\,\,{\text{to}}\,\,24 \) with incremental steps of 4). Bottom Jet white colour map of the above edge map. Rather than the centre Gaussian, other parameters of the model are: \( s = 2 \), and \( h = 8 \) (the Surround and Window ratios, respectively) (Reproduced by permission from [145]).
