Scale-Space Generation via Uncertainty Principles

چکیده
This study is concerned with the uncertainty principles which are related to the Weyl-Heisenberg, the SIM(2) and the Affine groups. A general theorem which associates an uncertainty principle to a pair of self-adjoint operators was previously used in finding the minimizers of the uncertainty principles related to various groups, e.g., the one and twodimensional Weyl-Heisenberg groups, the one-dimensional Affine group, and the two-dimensional similitude group of IR, SIM(2) = IR2× (IR+× SO(2)). In this study the relationship between the affine group in two dimensions and the SIM(2) group is investigated in terms of the uncertainty minimizers. Moreover, we present scale space properties of a minimizer of the SIM(2) group.

متن کاملHow Does Large-scale Wind Power Generation Affect Energy and Reserve Prices?
Intermittent nature of wind power faced ISO and power producers with new challenges. Wind power uncertainty has increased the required reserve capacity and deployment reserve. Consequently, large-scale wind power generation increases ISO costs and consequently reserve prices. On the other hand, since wind power producers are price taker, large-scale wind power generation decreases residual dema...
متن کاملMutual information aspects of scale space images
In image registration mutual information is a well-performing measure based on principles of uncertainty. Similarly, in image analysis the Gaussian scale space, based on minimal assumptions of the image, is used to derive intrinsic properties of an image. In this paper a combination of both methods is investigated. This results in a parametrized mutual information measure using local informatio...
