Journal ArticleDOI

On active contour models and balloons

TL;DR: A model of deformation which solves some of the problems encountered with the original method of energy-minimizing curves and makes the curve behave like a balloon which is inflated by an additional force.
Journal ArticleDOI

Three parietal circuits for number processing

TL;DR: The horizontal segment of the intraparietal sulcus appears as a plausible candidate for domain specificity: It is systematically activated whenever numbers are manipulated, independently of number notation, and with increasing activation as the task puts greater emphasis on quantity processing.
Journal ArticleDOI

The visual word form area: spatial and temporal characterization of an initial stage of reading in normal subjects and posterior split-brain patients.

TL;DR: For instance, this article found that the visual word form (VWF) system was activated only by stimuli presented in the right visual field, and that a significant influence of the word/non-word status on ERPs recorded over the left hemisphere was discernible for either hemifield in controls, while it affected only right-hemifield stimuli in callosal patients.
Journal ArticleDOI

Finite-element methods for active contour models and balloons for 2-D and 3-D images

TL;DR: A 3-D generalization of the balloon model as a3-D deformable surface, which evolves in 3D images, is presented and properties of energy-minimizing surfaces concerning their relationship with 3- D edge points are shown.
Journal ArticleDOI

The visual word form area: expertise for reading in the fusiform gyrus

TL;DR: It is argued that the interplay between the unique demands of word reading and the structural constraints of the visual system lead to the emergence of the Visual Word Form Area.
