Figure and ground: how the visual cortex integrates local cues for global organization

R von der Heydt, NR Zhang - Journal of neurophysiology, 2018 - journals.physiology.org
Inferring figure-ground organization in two-dimensional images may require different
complementary strategies. For isolated objects, it has been shown that mechanisms in visual …

Medium spatial frequencies mask edges most effectively

L Schmittwilken, M Maertens - Journal of Vision, 2022 - jov.arvojournals.org
Luminance discontinuities, ie edges, are important visual image features because they
demarcate the boundaries of objects in the physical world. Psychophysically, human edge …

Stimulus-specificity of surround-induced responses in primary visual cortex

Recent studies in mice challenge the traditional notion of the V1 receptive field (RF) showing
increases in V1 firing rates for stimuli presented in the surround, in the absence of a visual …

Consistent and robust determination of border ownership based on asymmetric surrounding contrast

K Sakai, H Nishimura, R Shimizu, K Kondo - Neural Networks, 2012 - Elsevier
Determination of the figure region in an image is a fundamental step toward surface
construction, shape coding, and object representation. Localized, asymmetric surround …

Fixational eye movements enable robust edge detection

L Schmittwilken, M Maertens - Journal of Vision, 2022 - jov.arvojournals.org
Human vision relies on mechanisms that respond to luminance edges in space and time.
Most edge models use orientation-selective mechanisms on multiple spatial scales and …

Consistency of border-ownership cells across artificial stimuli, natural stimuli, and stimuli with ambiguous contours

JK Hesse, DY Tsao - Journal of Neuroscience, 2016 - Soc Neuroscience
Segmentation and recognition of objects in a visual scene are two problems that are hard to
solve separately from each other. When segmenting an ambiguous scene, it is helpful to …

Figure-ground organization in natural scenes: Performance of a recurrent neural model compared with neurons of area V2

B Hu, R von der Heydt, E Niebur - eneuro, 2019 - eneuro.org
A crucial step in understanding visual input is its organization into meaningful components,
in particular object contours and partially occluded background structures. This requires that …
