Shape modelling via higher-order active contours and phase fields

Shape modelling via higher-order active contours and phase fields

This video was recorded at MUSCLE Conference joint with VITALAS Conference. For the most part, shape modelling has focused on modelling families of regions consisting of deviations around a given reference shape with a simple topology. There are applications; however, where the family of regions involved does not show such constrained behaviour. Cases where the number of objects is unknown a priori, or where the topology of the region may be otherwise complex (for example network shapes), require new techniques. 'Higher-order active contours' (HOACs) represent one approach to modelling such families of regions. By introducing explicit long-range interactions between region boundary points, HOACs can model families of regions sharing geometric properties without overly constraining region... Show More
