In this contribution, we are concerned with the detection and reened subvoxel localization of 3D point landmarks. We propose multi-step differential approaches which are generalizations of an existing two-step approach for subpixel localization of 2D point landmarks. This two-step approach combines landmark detection by applying a diierential operator with reened localization through a diierent...

We propose multi-step diierential procedures which are generalizations of an existing two-step procedure for subpixel localization of 2D point landmarks.

In this paper, we deal with the second order difference equation asymmetric nonlinearities on integer lattice and investigate distribution of zeros for continuous extensions positive semi-waves. The distance between two consecutive different semi-waves depends not only parameters problem but also position one these respect to lattice. We provide an explicit formula distance, which allows us obt...

Abstract We give a new class of equivalent norms for modulation spaces by replacing the window short-time Fourier transform Hilbert–Schmidt operator. The main result is applied to Cohen’s time-frequency distributions, Weyl operators and localization operators. In particular, any positive distribution with Schwartz kernel can be used an norm spaces. also obtain description as Wiener amalgam oper...

We define a Schrödinger operator on the half-space with discontinuous magnetic field having piecewise-constant strength and uniform direction. Motivated by applications in theory of superconductivity, we study infimum spectrum operator. give sufficient conditions direction such that aforementioned is an eigenvalue reduced model half-plane. use to new semiclassical problem bounded domains space,...
