Robust Online Matrix Factorization for Dynamic Background Subtraction [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2017 We propose an effective online background subtraction method, which can be robustly applied to practical videos that have variations in both foreground and background.

Smooth quantum-classical transition in photon subtraction and addition processes [PDF]
, 2009 Recently Parigi et al. [Science 317, 1890 (2007)] implemented experimentally the photon subtraction and addition processes from/to a light field in a conditional way, when the required operations were produced successfully only upon the positive outcome ...

Critical analysis of derivative dispersion relations at high energies [PDF]
, 2003 We discuss some formal and fundamental aspects related with the replacement of integral dispersion relations by derivative forms, and their practical uses in high energy elastic hadron scattering, in particular $pp$ and $\bar{p}p$ scattering.

Appearance of the canine meninges in subtraction magnetic resonance images [PDF]
, 2014 The canine meninges are not visible as discrete structures in noncontrast magnetic resonance (MR) images, and are incompletely visualized in T1‐weighted, postgadolinium images, reportedly appearing as short, thin curvilinear segments with minimal ...

Procedia - Social and Behavioral Sciences, 2010 This paper describes an action research that aimed at improving pupils’ performance in doing subtraction with regrouping of 1-digit numbers from 2-digit numbers and 2-digit numbers from 2-digit numbers. This study involved six Year 4 Malaysian Primary school pupils who were selected from 22 pupils who had sat for a test consisting of questions on ...

On the importance of background subtraction in the analysis of coronal loops observed with TRACE
, 2010 In the framework of TRACE coronal observations, we compare the analysis and diagnostics of a loop after subtracting the background with two different and independent methods.

Enhancing quantum entanglement for continuous variables by a coherent superposition of photon subtraction and addition [PDF]
, 2011 We investigate how the entanglement properties of a two-mode state can be improved by performing a coherent superposition operation of photon subtraction and addition, proposed by Lee and Nha [Phys. Rev. A 82, 053812 (2010)], on each mode.

Introduction to Neutrosophic Subtraction Algebra and Neutrosophic Subtraction Semigroup [PDF]
International Journal of Neutrosophic Science, 2020 The objective of this paper is to introduce and study the notion of neutrosophic subtraction algebras and neutrosophic subtraction semigroups. It also introduces the notion of neutrosophic ideals of neutrosophic subtraction semigroup and presents some of their basic properties.
