Lund University, Sweden, is developing a video analysis system for making long-term behavioural studies, primarily in complex urban environments. Road users are detected using the KLT (Kanade-LucasTomasi) interest point tracker. Trajectories are estimated using foreground–background segmentation, whereas speed is estimated using the shape analysis of interest points. The extracted trajectories ...

shape is regarded as one of outward characteristics of islamic seals. this characteristic, which is part of common traits of all different areas of seal studies, could be defined as framework of circumference of seals impression on written materials and documents, which in fact results from the shape of seals surfaces. shape has been considered as one of the ways of recognizing the administrati...

Background and Aim: One of the important characteristics of nickel-titanium (Ni-Ti) rotary files is their dentin removal ability. The purpose of this study was to compare One Shape and F6 SkyTaper files in terms of dentin removal from the mesiobuccal canals of extracted first mandibular molars. Materials and Methods: In this experimental study, 24 mesiobuccal canals of extracted first mandib...

Standard practice in quantitative structural neuroimaging is a segmentation into brain tissue, subcortical structures, fluid space and lesions followed by volume calculations of gross structures. On the other hand, it is evident that object characterization by size does only capture one of multiple aspects of a full structural characterization. Desirable parameters are local and global paramete...
