Foreground Detection in Multi-camera Surveillance System
نویسندگان
چکیده
In multi-camera surveillance system, the importance of each camera differs from each other and needs to be identified. In this paper, we develop an Edge-based Foreground Block Detection (EFBD) method to find out changing (foreground) blocks and then determine the importance of cameras based on EFBD. We also use H.264 codec to develop a multi-camera surveillance system which provides functions of auto alarm, dynamic recording, and foreground detection, and makes important cameras obtain better visual quality. The experimental results demonstrate that the proposed scheme can extract the foreground blocks efficiently and can handle the variations of light conditions. The detected foreground blocks can provide clues to better rate allocation and coding efficiency in our implemented multi-camera surveillance system.

Nighttime Foreground Pedestrian Detection Based on Three-Dimensional Voxel Surface Model
Pedestrian detection is among the most frequently-used preprocessing tasks in many surveillance application fields, from low-level people counting to high-level scene understanding. Even though many approaches perform well in the daytime with sufficient illumination, pedestrian detection at night is still a critical and challenging problem for video surveillance systems. To respond to this need...

Target detection and tracking is an important problem in the automatic surveillance system. This paper proposes a Combined Gaussian Hidden Markov Model based Kalman Filter (CGHMM-KF) scheme for tracking people in multiple camera sensor network for monitoring and tracking of target (person/vehicle) in secured area. To detect the target under different illumination conditions, HMM with Mixture of...
متن کاملSurveillance Camera Autocalibration based on Pedestrian Height Distributions
We propose a new framework for automatic surveillance camera calibration by observing videos of pedestrians walking through the scene. Unlike existing methods that require accurate pedestrian detection and tracking, our method takes noisy foreground masks as input and automatically estimates the necessary intrinsic and extrinsic camera parameters using prior knowledge about the distribution of ...
متن کاملActivity Discovery from Occlusion Primitives
Complex multi-agent interactions result in occlusion sequences which are a visual signature for the event. In this work, multi-agent interactions are tracked using a set of qualitative occlusion primitives derived based on the Persistence Hypothesis (objects continue to exist even when hidden from view). Variable length temporal sequences of occlusion primitives are shown to be well-correlated ...
متن کاملEvaluation of Probabilistic Occupancy Map People Detection for Surveillance Systems
In this paper, we evaluate the Probabilistic Occupancy Map (POM) pedestrian detection algorithm on the PETS 2009 benchmark dataset. POM is a multi-camera generative detection method, which estimates ground plane occupancy from multiple background subtraction views. Occupancy probabilities are iteratively estimated by fitting a synthetic model of the background subtraction to the binary foregrou...
