Efficient Incorporation of Motionless Foreground Objects for Adaptive Background Segmentation

In this paper, we want to exploit the knowledge obtained from those detected objects which are incorporated into the background model since they cease their movement. These motionless foreground objects should be handled in security domains such as video surveillance. This paper uses an adaptive background modelling algorithm for movingobject detection. Those detected objects which present no m...

Improving Foreground Detection for Adaptive Background Segmentation

This paper tries to manage with the nonincorporation of erroneous foreground objects to the background model, and the incorporation of those detected objects which cease their movement. These newly motionless foreground objects should be handled in security domains such as video surveillance. This paper uses an adaptive background modelling algorithm for movingobject detection. Those detected o...

When should one subtract background fluorescence in two color microarrays?

Two color microarrays are a powerful tool for genomic analysis, but have noise components that make inferences regarding gene expression inefficient and potentially misleading. Background fluorescence, whether attributable to non-specific binding or other sources, is an important component of noise. The decision to subtract fluorescence surrounding spots of hybridization from spot fluorescence ...

Nicmos Measurements of the near Infrared

— This paper addresses the nature of the near infrared background. We investigate whether there is an excess background at 1.4 microns, what is the source of the near infrared background and whether that background after the subtraction of all known sources contains the signature of high redshift objects (Z > 10). Based on NICMOS observations in the Hubble Ultra Deep Field and the Northern Hubb...

Paper VERY HIGH BACKGROUND RADIATION AREAS OF RAMSAR, IRAN: PRELIMINARY BIOLOGICAL STUDIES

People in some areas of Ramsar, a city in northern Iran, receive an annual radiation absorbed dose from background radiation that is up to 260 mSv y 1, substantially higher than the 20 mSv y 1 that is permitted for radiation workers. Inhabitants of Ramsar have lived for many generations in these high background areas. Cytogenetic studies show no significant differences between people in the hig...
