Wallflower: principles and practice of background maintenance
Proceedings of the Seventh IEEE International Conference on Computer Vision, 1999Background maintenance is a frequent element of video surveillance systems. We develop Wallflower, a three-component system for background maintenance: the pixel-level component performs Wiener filtering to make probabilistic predictions of the expected background; the region-level component fills in homogeneous regions of foreground objects; and the ...

Spatially correlated background subtraction, based on adaptive background maintenance
Journal of Visual Communication and Image Representation, 2012Moving object detection in dynamic backgrounds remains a challenging problem. Our earlier work established that the background subtraction using the covariance matrix descriptor is robust for dynamic backgrounds. The work proposed herein extends this approach further, using just two features-Hu moment and intensity.

Multiple Layer Based Background Maintenance in Complex Environment
Third International Conference on Image and Graphics (ICIG'04), 2005A fast and efficient multiple layer background maintenance model is built to conserve the original and the current background separately. Fusing the properties of object motion in image pixels and the changes between the input video and the multiple background layers, this method could handle various sources of scene changes, including ghosts, abandon ...

A fast background scene modeling and maintenance for outdoor surveillance
Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002We describe fast background scene modeling and maintenance techniques for real time visual surveillance system for tracking people in an outdoor environment. It operates on monocular gray scale video imagery or on video imagery from an infrared camera.

Racial background is a determinant factor in the maintenance dosage of Warfarin
International Journal of Hematology, 2003Warfarin is a drug commonly used in the prevention of thromboembolic events. There have been reports suggesting that racial background may influence warfarin dose requirements. Malaysia is a multiracial country in which there are 3 major races, Malay, Chinese, and Indian.

A Background Maintenance Model in the Spatial-Range Domain
2004In this article a background maintenance model defined by a finite set of codebook vectors in the spatial-range domain is proposed. The model represents its current state by a foreground and a background set of codebook vectors. Algorithms that dynamically update these sets by adding and removing codebook vectors are described.

SummaryPodoplanin, PDPN, is a mucin‐type transmembrane glycoprotein widely expressed in many tissues, including lung, kidney, lymph nodes, and mineralized tissues. Its function is critical for lymphatic formation, differentiation of type I alveolar epithelial lung cells, and for bone response to biomechanical loading.
