Non-Linear Scale-Spaces Isomorphic to the Linear Case
نویسنده
چکیده
An in nite dimensional class of isomorphisms is considered, relating a particular class of nonlinear scale-spaces to the well-established linear case. The nonlinearity pertains to an invertible mapping of grey-values, which can be adapted so as to account for external knowledge. This is particularly interesting for applications such as segmentation in medical imaging, whereby one is in possession of a model relating tissue types to image grey-values. It is moreover of interest in de ning a consistent scale-space representation of vector-valued and multispectral images.

Non-linear ergodic theorems in complete non-positive curvature metric spaces
Hadamard (or complete $CAT(0)$) spaces are complete, non-positive curvature, metric spaces. Here, we prove a nonlinear ergodic theorem for continuous non-expansive semigroup in these spaces as well as a strong convergence theorem for the commutative case. Our results extend the standard non-linear ergodic theorems for non-expansive maps on real Hilbert spaces, to non-expansive maps on Ha...
متن کاملCyclic wavelet systems in prime dimensional linear vector spaces
Finite affine groups are given by groups of translations and di- lations on finite cyclic groups. For cyclic groups of prime order we develop a time-scale (wavelet) analysis and show that for a large class of non-zero window signals/vectors, the generated full cyclic wavelet system constitutes a frame whose canonical dual is a cyclic wavelet frame.

In this paper we investigate the algebraic properties of dimension of fuzzy hypervector spaces. Also, we prove that two isomorphic fuzzy hypervector spaces have the same dimension.
متن کاملFisher’s Linear Discriminant Analysis for Weather Data by reproducing kernel Hilbert spaces framework
Recently with science and technology development, data with functional nature are easy to collect. Hence, statistical analysis of such data is of great importance. Similar to multivariate analysis, linear combinations of random variables have a key role in functional analysis. The role of Theory of Reproducing Kernel Hilbert Spaces is very important in this content. In this paper we study a gen...
متن کاملStrictly singular operators and isomorphisms of Cartesian products of power series spaces
V. P. Zahariuta, in 1973, used the theory of Fredholm operators to develop a method to classify Cartesian products of locally convex spaces. In this work we modify his method to study the isomorphic classification of Cartesian products of the kind E0 a E1 b where 1 % p;q < 1 , p j q, a an n1 and b bn n1 are sequences of positive numbers and E0 a, E1 b are respectively `p-finite...
