This article presents feedback mechanisms between early visual processes, such as perceptual grouping, stereopsis and depth reconstruction, that allow the system to reduce this ambiguity and improve early representation of visual information. In the first part, the article proposes a local perceptual grouping algorithm that - in addition to commonly used geometric information - makes use of a novel multi-modal measure between local edge/line features. The grouping information is then used to: 1\\) disambiguate stereopsis by enforcing that stereo matches preserve groups; and 2\\) correct the reconstruction error due to the image pixel sampling using a linear interpolation over the groups. The integration of mutual feedback between early vision processes is shown to reduce considerably ambiguity and noise without the need for global constraints."],["dc.identifier.doi","10.1371/journal.pone.0010663"],["dc.identifier.fs","580961"],["dc.identifier.pmid","20544006"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7201"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60384"],["dc.language.iso","en"],["dc.notes","The work described in this paper was funded by the European projects PACOplus and IRFO.
