The notion of kernels, recently introduced, has drawn much interest as it allows one to obtain
nonlinear algorithms from linear ones in a simple and elegant manner. This, in conjunction …

Local image features or interest points provide compact and abstract representations of
patterns in an image. In this paper, we extend the notion of spatial interest points into the …

The fact that objects in the world appear in different ways depending on the scale of
observation has important implications if one aims at describing them. It shows that the …

An inherent property of objects in the world is that they only exist as meaningful entities over
certain ranges of scale. If one aims to describe the structure of unknown real-world signals …

The sixth edition of this worldwide used textbook was thoroughly-vised and extended.
Throughout the whole text you will? nd numerous improvements, extensions, and updates …

The problem of scale pervades both the natural sciences and the vi sual arts. The earliest
scientific discussions concentrate on visual per ception (much like today!) and occur in …

When computing descriptors of image data, the type of information that can be extracted may
be strongly dependent on the scales at which the image operators are applied. This article …

This article presents:(i) a multiscale representation of grey-level shape called the scale-
space primal sketch, which makes explicit both features in scale-space and the relations …

The performance of matching and object recognition methods based on interest points
depends on both the properties of the underlying interest points and the choice of …

Many approaches have been proposed to solve the problem of finding the optic flow field of
an image sequence. Three major classes of optic flow computation techniques can …
