Background subtraction under varying illumination
Background subtraction is widely used as an effective method for detecting moving objects in a video image. However, background subtraction requires a prerequisite in that image variation cannot be observed, and the range of application is limited. Proposed in this research paper is a method for detecting moving objects by using background subtraction that can be applied to cases in which the i...
متن کاملMaking Background Subtraction Robust to Various Illumination Changes
Background subtraction is an important step used to segment moving regions in surveillance videos. Modern background subtraction techniques can handle gradual illumination changes but can easily be confused by rapid ones. In particular, varying illuminations cause significant changes in the representation of a scene in different spaces, which in turn results in the high levels of failure in suc...
متن کاملShift of visual fixation dependent on background illumination.
Visual fixation, the act of maintaining the eyes directed toward a location of interest, is a highly skilled behavior necessary for high-level vision in primates. In spite of its significance, visual fixation is not well understood; it is not even clear what attributes of the visual input are used to control fixation. Here we show, in four Macaca fascicularis monkeys, that the position the eyes...
متن کاملReal Time Illumination Invariant Background Subtraction Using Local Kernel Histograms
Constant background hypothesis for background subtraction algorithms is often not applicable in real environments because of shadows, reflections, or small moving objects in the background: flickering screens in indoor scenes, or waving vegetation in outdoor ones. In both indoor and outdoor scenes, the use of color cues for background segmentation is limited by illumination variations when ligh...
متن کاملThe Dependence of WFPC2 Charge Transfer Efficiency on Background Illumination
We have examined the charge transfer efficiency (CTE) of WFPC2's CCDs near the end of mission as a function of background illumination. Internal lamps were used to flash the CCDs before or after external exposures of ! Cen to produce average background signals of 0–160 e. These signals span the natural sky backgrounds observed in ~99% of archived WFPC2 science images. Most of the stellar flux l...
