The GLAST Background Model [PDF]

open access: yesAIP Conference Proceedings, 2007
In order to estimate the ability of the GLAST/LAT to reject unwanted background of charged particles, optimize the on-board processing, size the required telemetry and optimize the GLAST orbit, we developed a detailed model of the background particles that would affect the LAT.

Background Subtraction via Generalized Fused Lasso Foreground Modeling [PDF]

open access: yes, 2015
Background Subtraction (BS) is one of the key steps in video analysis. Many background models have been proposed and achieved promising performance on public data sets. However, due to challenges such as illumination change, dynamic background etc.

Cosmic Superstring Scattering in Backgrounds [PDF]

open access: yes, 2006
We generalize the calculation of cosmic superstring reconnection probability to non-trivial backgrounds. This is done by modeling cosmic strings as wound tachyon modes in the 0B theory, and the spacetime effective action is then used to couple this to ...

An Empirically Based Calculation of the Extragalactic Infrared Background [PDF]

open access: yes, 1997
Using the excellent observed correlations among various infrared wavebands with 12 and 60 micron luminosities, we calculate the 2-300 micron spectra of galaxies as a function of luminosity.

TensorMoG: A Tensor-Driven Gaussian Mixture Model with Dynamic Scene Adaptation for Background Modelling

open access: yesSensors, 2020
Decades of ongoing research have shown that background modelling is a very powerful technique, which is used in intelligent surveillance systems, in order to extract features of interest, known as foregrounds.

Modeling Extragalactic Foregrounds and Secondaries for Unbiased Estimation of Cosmological Parameters From Primary CMB Anisotropy [PDF]

open access: yes, 2011
Using the latest physical modeling and constrained by the most recent data, we develop a phenomenological parameterized model of the contributions to intensity and polarization maps at millimeter wavelengths from external galaxies and Sunyaev-Zeldovich ...

Moving Object Detection Using Scanning Camera on a High-Precision Intelligent Holder

open access: yesSensors, 2016
During the process of moving object detection in an intelligent visual surveillance system, a scenario with complex background is sure to appear. The traditional methods, such as “frame difference” and “optical flow”, may not able to deal with the ...

Modeling dense stellar systems: background [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractI provide some background about recent efforts made in modeling dense stellar systems, within the context of the MODEST initiative. During the last four years, we have seen more than fifteen MODEST workshops, with an attendance between twenty and a hundred participants, and topics ranging from very specialized discussions to rather general ...

An Overview of Background Modeling for Detection of Targets and Anomalies in Hyperspectral Remotely Sensed Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
This paper reviews well-known classic algorithms and more recent experimental approaches for distinguishing the weak signal of a target (either known or anomalous) from the cluttered background of a hyperspectral image.

A Catalog of Galaxy Clusters Observed by XMM-Newton [PDF]

open access: yes, 2007
Aims: We present a uniform catalog of the images and radial profiles of the temperature, abundance, and brightness for 70 clusters of galaxies observed by XMM-Newton.
