Image formation of a two-dimensional input image can be quantified by imposing an image induced connection and computing the associated torsion and curvature. The latter aspects of image formation are especially nonvanishing at sets of discontinuities and non-isolated singularities, such as ridges and ruts.

Optical flow in the scale space
1997There exists optical flow in the multiscale representation of an image if this representation is viewed as an image sequence in the “time” domain. The ill-posed tracking problem in the scale-space can be robustly solved by this method. The perceptual effect of any multiscale representation can be greatly improved by the so-called “pull-back” technique.

Scale spaces allow us to organize, compare and analyse differently sized structures of an object. In this work, we present and compare five ways of discretizing the Gaussian scale-space: sampling Gaussian distributions; recursively calculating Gaussian approximations; using Splines; approximating by first-order generators; and finally, by a new method ...

Local appropriate scale in morphological scale-space
1996This paper discusses the problem of selecting appropriate scales for region detection prior to feature localization. We argue that an approach in morphological opening-closing scale-space is better than one in Gaussian scale-space. The proposed operator is based on a new shape decomposition method called morphological band-pass filter that decomposes ...
