Fig. 2From: Bioplausible multiscale filtering in retino-cortical processing as a mechanism in perceptual grouping Left 3D surface of a Difference of Gaussian filter with the scale of the centre Gaussian equal to 8 (\( \sigma_{c} = 8 \)). The Surround ratio is \( s = 2 \), and the Window ratio is \( h = 8 \). Right Top view (2D) of the DoG filter. Window size is 65 × 65. Jet white colour map is used to display the graph.
