Computation of Ridges via Pullback Metrics from Scale Spaceaps to other parameters, such as an orientation, as well. Assigning to each point the parameter values that yield the maximum value of the convolution integral gives a map from points in the image to the space of parameters by which the given property is measured. The range of this map is the optima

Qualitative Multi-scale Feature Hierarchies for Object Trackinglations between image structures at different scales. The idea is to track all image features individually, and to use the qual- itative feature relations for resolving ambiguous matches and for intro- ducing feature hypotheses whenever image features are mismatched or lost. Compared to more traditi

Riemannian Drums, Anisotropic Curve Evolution and Segmentationof the curve and potential steady states tend to be difficult to determine numerically, especially in noisy or low-contrast situations. Initial curves shrink past the steady state and soon vanish. In this paper, anisotropic metrics are considered which remedy the situation by taking the orientation

An Active Contour Model without Edgesctional for segmentation and level sets. Our model can detect objects whose boundaries are not necessarily defined by gra- dient. The model is a combination between more classical active contour models using mean curvature motion techniques, and the Mumford-Shah model for segmentation. We minimize a

A Compact and Multiscale Image Model Based on Level Sets sets representation which offers most of the prop- erties sought to a good segmentation: the borders are located at the per- ceptual edges; they are invariant by affine map and by contrast change; they are sorted according to their perceptual significance using a scale parameter. At last, a compact

Morphological Scale Space and Mathematical Morphologyear smoothing methods of a signal or an image boils down to the application to the signal of the Heat Equation. In this survey, we explain how a similar analysis can be performed for image iterative smoothing by contrast invariant monotone operators. In particular, we prove that all iterated affine

Scale-Space from a Level Lines Treeometric information present in the image, sepa- rated from the contrast information. This structure allows to suppress easily some shapes without affecting the others, which yields a peculiar kind of scale-space, where the information present at each scale is already present in the original image.
