A new and simple shape descriptor based on a non-parametric multiscale model
In this paper, we present a new and robust shape descriptor, which can be efficiently used to quickly prune a search for similar shapes in a large image database. The proposed sha...

Stabilisation of Active Contours Using Tangential Evolution: An Application to Tracking
— Active contours are very widely used in computer vision problems. Their usage has a typical problem, that of bunching together of curve points. This becomes apparent especially...

Epipolar Geometry from the Deformation of an Active Contour
An active contour is used to track a target in a sequence recorded by a walking robot in an unstructured scene . The deformations of the contour are analysed in order to extract t...
