Abstract [en]

An eye movement mechanism with the task of tracking textureboundaries has been simulated. Gabor phase information has been dynamically  used in order to track regionboundaries. The tracking has been initiated manually froma point nearby a texture boundary with an initial boundary direction estimate. A filter selection strategy depending onthe azimuth angles of the receptive fields, and a control mechanism relying onphase discontinuites which are computed through means of magnitudesand magnitude of means of the complex filter responses have been devised.The experiments suggest that letting the Gabor phase play a dynamic role in boundary tracking results in accuratetracking at pixel resolution even when the texturesdiffer only in phase. As a by product tracking segregates textured regions.
