Jordan Form and Quantum Tomography [PDF]
arXiv, 2015 In this brief article we indicate a connection between Jordan normal form of a square matrix and the stroboscopic approach to quantum tomography. We show that the index of cyclicy of a generator of evolution, which receives much attention in the stroboscopic tomography, can be defined and computed by referring to the Jordan decomposition of a square ...

Multirate Spectral Domain Optical Coherence Tomography [PDF]
arXiv, 2023 Optical coherence tomography is state-of-the-art in non-invasive imaging of biological structures. Spectral Domain Optical Co-herence Tomography is the popularly used variation of this technique, but its performance is limited by the bandwidth and res-olution of the system.

Fast Image Segmentation Using Two-Dimensional Otsu Based on Estimation of Distribution Algorithm
Journal of Electrical and Computer Engineering, 2017 Traditional two-dimensional Otsu algorithm has several drawbacks; that is, the sum of probabilities of target and background is approximate to 1 inaccurately, the details of neighborhood image are not obvious, and the computational cost is high. In order

Cone beam computed tomography: basics and applications in dentistry
Journal of Istanbul University Faculty of Dentistry, 2017 The introduction of cone beam computed tomography (CBCT) devices, changed the way oral and maxillofacial radiology is practiced. CBCT was embraced into the dental settings very rapidly due to its compact size, low cost, low ionizing radiation exposure ...

Efficient quantum state tomography with auxiliary Hilbert space [PDF]
arXiv, 2019 Quantum state tomography is an important tool for quantum communication, computation, metrology, and simulation. Efficient quantum state tomography on a high dimensional quantum system is still a challenging problem. Here, we propose a novel quantum state tomography method, auxiliary Hilbert space tomography, to avoid pre-rotations before measurement ...
