Fig. 7From: Bioplausible multiscale filtering in retino-cortical processing as a mechanism in perceptual groupingDetected houghlines (centre) for two scales of 2 and 4 (\( \sigma_{c} = 2,\,4 \)) from the edge map of the Complex Bulge pattern (top). The two images at the bottom of the figure are zoomed-in versions of the two images at the centre row.
