Detecting Tree Distributed Predicates

2012 41st International Conference on Parallel Processing Workshops, 2012
In a large-scale locality-driven network, knowing the state of a local area is sometimes necessary due to either interactions being local and driven by neighborhood proximity or the users being interested in the state of a certain region. We propose locality-aware predicates that aim at detecting a predicate within a specified area.

Wheelchair Detection Using Cascaded Decision Tree

IEEE Transactions on Information Technology in Biomedicine, 2010
One of the major goals of healthcare systems is to automatically monitor patients of special needs and alarm the caregivers for providing assistant. In this paper, an efficient single-camera multidirectional wheelchair detector based on a cascaded decision tree (CDT) is proposed to detect a wheelchair and its moving direction simultaneously from video ...

Binary Partition Trees for Object Detection

IEEE Transactions on Image Processing, 2008
This paper discusses the use of Binary Partition Trees (BPTs) for object detection. BPTs are hierarchical region-based representations of images. They define a reduced set of regions that covers the image support and that spans various levels of resolution. They are attractive for object detection as they tremendously reduce the search space.

DETECTION OF DECAY IN TREES

Arboricultural Journal, 1999
Summary A number of devices are available for the detection and assessment of decay and other internal defects in trees. A brief description of the principles of these devices is provided, together with a discussion of their efficacy and the diagnostic value of the information that they provide.

Tree detection in LiDAR data

2006 IEEE Southwest Symposium on Image Analysis and Interpretation, 2006
In this paper, we present an approach to detecting trees in registered aerial image and range data obtained via LiDAR. The motivation for this problem comes from automated 3D city modeling, in which such data is used to generate the models. Representing the trees in these models is problematic because the data are usually too sparsely sampled in tree ...

Decision tree for corner detection

2015 IEEE International Conference on Signal Processing, Informatics, Communication and Energy Systems (SPICES), 2015
Corner detection is a important task in low level vision. Detecting corners helps one to establish similarity between two or more images. Traditional approaches for corner detection involve finding significant variation around a pixel neighbourhood in two different directions.

Early detection of tree faults

22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013
Faults due to falling trees happen frequently. At the moment a tree falls on a transmission line, the impedance path of the tree is not fully conductive. Therefore, the tree resistance at these early stages is very high and hard to detect. As time passes, the conductivity of the tree increases (less fault resistance Rf) till the point where Rf is low ...

Water trees in cables: generation and detection

IEE Proceedings - Science, Measurement and Technology, 1999
The generation mechanism of water trees is discussed, and secondly the consequences of the morphology of the water trees on the chances to detect them in a buried cable by means of an appropriate diagnostic system are discussed.

Rule-based detection of intrathoracic airway trees

IEEE Transactions on Medical Imaging, 1996
New sensitive and reliable methods for assessing alterations in regional lung structure and function are critically important for the investigation and treatment of pulmonary diseases. Accurate identification of the airway tree will provide an assessment of airway structure and will provide a means by which multiple volumetric images of the lung at the
