Local visual homing is the process of determining the direction of movement required to return an agent to a goal location by comparing the current image with an image taken at the goal, known as the snapshot image. One way of accomplishing visual homing is by computing the correspondences between features and then analyzing the resulting flow field to

Artists pictures rarely have photo-realistic detail. Tools to create pictures from digital photographs might, therefore, include methods for removing detail. These tools such as Gaussian and anisotropic diffusion filters and connected-set morphological filters (sieves) remove detail whilst maintaining scale-space causality, in other words new detail is

, 1966 In this chapter we shall study a variation of so called “decomposition of identity”, a strange and inadequate name for collections E λ of projectors depending on a real (or complex) parameter λ, and strongly related to selfadjoint or normal operators.

In this paper we propose a novel type of scales-spaces which is emerging from the family of inhomogeneous pseudodifferential equations $(I - \tau\Delta)^{\frac{t}{2}}u$ with τ ≥ 0 and scale parameter t ≥ 0. Since they are connected to the convolution semi-group of Bessel potentials we call the associated operators {R$^{n}_{t,{ \tau}}$ | 0≤ τ,t} either ...

Spaces and Scales of Leadership
2016This chapter analyzes the various scales (meaning the different geographical levels; cf. Glossary for the definition of geography) at which leaders are involved and to which they are related. Leaders are, in fact, influenced by, and influence, the transformation and emergence of numerous spaces.

Image and Vision Computing, 1997
It is argued that image measurements should satisfy two requirements of physical plausibility: the measurements are of non-zero scale and non-zero imprecision; and two required invariances, nothing is lost by expanding the image and nothing is lost by increasing the contrast of the image.

So far we have studied linear parabolic evolution equations in a fixed Banach space. However, we have already seen, in connection with considerations of higher regularity and problems with variable domains, that it is useful and necessary to consider induced equations in interpolation spaces as well.

Viewing images as distributions of light quanta enables an information theoretic study of image structures on different scales. This article combines Shannon's entropy and Witkin and Koenderink's scale-space to establish a precise connection between the heat equation and the thermodynamic entropy in scale-space.

In this paper we extend the notion of Poisson scale-space. We propose a generalisation inspired by the linear parabolic pseudodifferential operator $\sqrt{-\Delta+m^2}-m$, 0≤m, connected with models of relativistic kinetic energy from quantum mechanics.
