We propose a novel feature, local histogram of figure/ground segmentations, for robust and efficient background subtraction (BGS) in dynamic scenes (e.g., waving trees, ripples in water, illumination changes, camera jitters, etc.). We represent each pixel as a local histogram of figure/ground segmentations, which aims at combining several candidate solutions that are produced by simple BGS algo...

Biobanks are a key resource in unravelling the association between genetic background, lifestyle and environmental determinants of the incidence, natural course and treatment response for various complex diseases and health traits. Biobanks are goldmines for epidemiological research, provided that they are set up properly, enable multicentre collaboration, and are available for use by all serio...

The present study assessed the prevalence of asthma and allergy, and estimated the importance of genetic and environmental influences on asthma and allergy liability and their association. Longitudinal data on self-reported, doctor-diagnosed asthma and allergy were collected in over 14,000 individuals registered with the Netherlands Twin Register. Structural equation modeling was used for univa...

abstract aim and background: studying the role of background causes and biomarkers on early onset cardiovascular diseases' incidence as one important issue is need for prevention of these diseases. the purpose of this study was to identify the role of background factors and biomarkers for early onset cardiovascular diseases' incidence. methods and materials: in a descriptive study with cross-se...

Three areas of activity in the field of low-level radiation epidemiology have been reviewed. They concern the questions of cancer risk related to antenatal X-ray exposure, occupational radiation exposure, and residence in areas of real or supposed increased levels of radiation. Despite the a priori unlikelihood of useful information developing from studies in any of these areas, such investigat...

A real time visualisation method, to be used in mobile gamma-spectrometric search operations using standard detector systems is presented. The new method, called deviation display, uses a modified waterfall display to present relative changes in spectral data over energy and time. Using unshielded (137)Cs and (241)Am point sources and different natural background environments, the behaviour of ...

Previous articles have described a process for the elimination of background from fingerprint and other images by subtracting the background. Two options, f iltration and erasure, have been discussed. Channel subtraction, either in RGB (Red, Green, Blue) or HSI (Hue, Saturation, Intensity) mode, can also be effected with variable results. There exists a fourth option: substituting another item ...
