Scene background initialization: A taxonomy

Pattern Recognition Letters, 2017
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. Limited attention to the problem is given in the literature on background modeling, that mainly regards model representation and updating.

Exemplar-based background model initialization

Proceedings of the third ACM international workshop on Video surveillance & sensor networks, 2005
Most of the automated video-surveillance applications are based on background (BG) subtraction techniques, that aim at distinguishing moving objects in a static scene. These strategies strongly depend on the BG model, that has to be initialized and updated. A good initialization is crucial for the successive processing.

Background Initialization in Cluttered Sequences

2006 Conference on Computer Vision and Pattern Recognition Workshop (CVPRW'06), 2006
In this paper we propose a technique to robustly estimate the background in a cluttered sequence, i.e., a sequence where occluding objects persist in the same position for a considerable portion of time. As pixel-level heuristic are not sufficient in this case, we introduce spatial support. First the sequence is subdivided in patches that are clustered

CNN-based initial background estimation

2016 23rd International Conference on Pattern Recognition (ICPR), 2016
Despite being an essential prerequisite at the basis of many applications ranging from surveillance to computational photography, the problem of initial background estimation seems to be marginally investigated. In this paper, we present a reliable CNN-based solution to estimate the initial background (BG) of a scene, given not necessarily a whole ...

Integrated Myocardial Management: Background and Initial Application

Journal of Cardiac Surgery, 1995
This report describes the technique of integrated myocardial management, which combines the advantages of various cardioprotective strategies to compensate for their individual shortcomings. This approach coordinates the myocardial protective techniques with the continuity of the operation so that the surgical procedure is never interrupted.

SVD-Based Tensor-Completion Technique for Background Initialization

IEEE Transactions on Image Processing, 2018
Extracting the background from a video in the presence of various moving patterns is the focus of several background-initialization approaches. To model the scene background using rank-one matrices, this paper proposes a background-initialization technique that relies on the singular-value decomposition (SVD) of spatiotemporally extracted slices from ...

Multilevel Background Initialization using Hidden Markov Models

First ACM SIGMM international workshop on Video surveillance - IWVS '03, 2003
Most of the automated video-surveillance applications are based on the process of background modelling, aimed at discriminating motion patterns of interest at pixel, region or frame level in a nearly static scene. The issues characterizing an ordinary background modelling process are typically three: the background model representation, the ...

Parkinson's Disease: Background, Diagnosis, and Initial Management

Clinics in Geriatric Medicine, 2006
Parkinson's disease is a common neurodegenerative disorder associated with aging. After essential tremor, it is the most common movement disorder of the elderly. Parkinson's disease is the most common disabling movement disorder. This article reviews the major clinical features, differential diagnosis, approach to diagnosis, and initial management of ...

Fast Background Initialization with Recursive Hadamard Transform

2010 7th IEEE International Conference on Advanced Video and Signal Based Surveillance, 2010
In this paper, we present a new and fast techniquefor background estimation from cluttered image sequences.Most of the background initialization approaches developedso far collect a number of initial frames and then requirea slow estimation step which introduces a delay wheneverit is applied.
