This paper provides experimental and theoretical evidence for the existence of contiguous failure regions in the program input space (`blob' defects). For real-time systems where successive input values tend to be similar, blob defects can have a major impact on the software survival time because the failure probability is not constant. For example, with a `random walk' input sequence, the prob...

In this paper we describe a surveillance system that is not only able to detect blobs and track them but also determines if a blob is a person. The given blob is segmented into sub-regions. A person model is fit to these regions such that a likelihood measure is maximized. The likelihood measure depends on the number of identified body parts, their length, location, and aspect ratio. The method...

Edge, texture, and shape features: (a) edges extracted from image 5a; (b) edges extracted from image 5b; (c) simple texture measure applied to image 5b; (d) thresholded texture measure yields a blob corresponding to the ordnance ; (e) left image of a stereo pair of the totally exposed ordnance; (f) range image from the stereo pair; (g) elevation map from th...

This paper investigates the combined use of ambient and wearable sensing for inferring changes in patient behaviour patterns. It has been demonstrated that with the use of wearable and blob based ambient sensors, it is possible to develop an effective visualization framework allowing the observation of daily activities in a homecare environment. An effective behaviour modelling method based on ...

The Nuchal Translucency thickness measurement is made to identify the Down Syndrome in screening first trimester fetus and presented in this paper. The mean shift analysis and canny operators are utilized for segmenting the nuchal translucency region and the exact thickness has been estimated using Blob analysis. It is observed from the results that the fetus in the 14th week of Gestation is ex...

Abstract Cross-field transport of particles in the boundary region magnetically confined fusion plasmas is dominated by turbulence. Blobs, intermittent turbulent structures with large amplitude and a filamentary shape appearing scrape-off layer (SOL), are known from theoretical experimental studies to be main contributor cross-field particle transport. The dynamics blobs differs depending on va...

conclusion no significant differences were found among observers or voxel sizes, with high az results reported for all groups. results no significant differences were found among observers or voxel sizes, with high average z (az) results being reported for all groups. both intra- and inter-observer agreement values were relatively better for 3d accuitomo 170 images than the images from newtom 3...
