Initial situation and background
1989This description of the initial situation, which precedes the compilation of scenarios, examines a number of different subjects. A brief survey is provided of the scale of the damage to public health caused by accidents (section 2.2). Subsequently the way this problem has evolved in recent decades, and the background to those trends, will be examined ...

Adaptive bootstrapping management by keypoint clustering for background initialization
Pattern Recognition Letters, 2017Abstract The availability of a background model that describes the scene is a prerequisite for many computer vision applications. In several situations, the model cannot be easily generated when the background contains some foreground objects (i.e., bootstrapping problem).

A background model initialization algorithm for video surveillance
Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002Many motion detection and tracking algorithms rely on the process of background subtraction, a technique which detects changes from a model of the background scene. We present a new algorithm for the purpose of background model initialization. The algorithm takes as input a video sequence in which moving objects are present, and outputs a statistical ...

Modelling of initial reference frame for background subtraction
2010 6th International Colloquium on Signal Processing & its Applications, 2010Background subtraction techniques are commonly used for separating the objects of interest from its background. Most of the techniques required an initial reference or background frame prior to updating the next sequence during tracking process. In this paper, development of the initial frame reference model is afforded by analysing all examples in ...

A probabilistic SVM approach for background scene initialization
Proceedings. International Conference on Image Processing, 2003Visual tracking systems using background subtraction have been very popular largely due to their efficiency in extracting moving objects. However, such systems often compute the reference background by assuming no moving objects are present during the initialization stage, though the assumption may not be realistic.

Background to the Social Protection Initiative
2013This chapter serves as an introduction to provide background information on the social protection floor initiative and to outline the progress and constraints in achieving the Millennium Development Goals (MDGs). The context of globalization is provided, and the recent global financial crisis, which both influence the development of recent social ...

Initialization of Fractional Differential Equations: Background and Theory
Volume 5: 6th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2007It has been known that the initialization of fractional operators requires time-varying functions, a complicating factor. This paper simplifies the process of initialization of fractional differential equations by deriving Laplace transforms for the initialized fractional integral and derivative that generalize those for the integer-order operators ...

Pixel-based background initialization using spatio-temporal restrictions
2012A precise background detection is required for video surveillance applications in order to detect foreground objects. However, in the presence of cluttered scenes, standard techniques for background segmentation can fail. In this work we present a new technique for foreground detection that is able to detect the correct background in complex scenes. It

Benchmarking Scene Background Initialization
2015Given a set of images of a scene taken at different times, the availability of an initial background model that describes the scene without foreground objects is the prerequisite for a wide range of applications, ranging from video surveillance to computational photography.
