background and aims. the aim of this study was to investigate the relative frequency of developmental odontogenic cysts in an iranian population. materials and methods. in this study 245 cysts from both jaws, treated in the faculty of dentistry at tabriz university of medical sciences during a 10-year period from 1998 to 2008, were analyzed in order to evaluate the incidence of such cysts. we h...

Polygon search is the problem of nding unpredictable mobile intruders in a polygonal region using one or more mobile searchers with various levels of vision, where both the searcher and intruders are allowed to move freely within the region. In this paper we consider a variant of this problem, termed boundary search, in which a single searcher has to nd the intruders from the boundary of the re...

We present a fast conservative from-region visibility method capable of handling 3D models using arbitrary 3D triangles as occluders. The from-region visibility problem is considered significantly harder than the from-point visibility problem, since it is inherently 4-dimensional. Our occlusion culling method is based on factorizing the 4D visibility problem into horizontal and vertical compone...

Broca's region, classically considered a motor speech-production area, is involved in action understanding and imitation. It also seems to help in sequencing of actions. Broca's region might have evolved for interindividual communication, both by gestures and speech.

This paper presents an approach to automatically extract human body region from color photos, which introduces trimap shape updating into iterated GrabCut image segmentation technique. It is based on an observation that human torso is relatively stable in appearance compared with various human poses formed by hands and feet, and on a fact that estimation on a small region is more accurate than ...

The selection of salient regions in an image is the first step in many computer vision algorithms, e.g. objects recognition, classification or tracking. Our hypothesis is that local image statistics are indicative for saliency. We combine natural image statistics with the detection of salient regions. Particularly, we consider the integrated Weibull distribution as a parameterized model, which ...

459 As we mark World Hepatitis Day on 28 July, our attention naturally focuses on the relentless battle to eliminate viral hepatitis from populations suffering under the heavy toll of this communicable disease. The theme for World Hepatitis Day this year is “Eliminate Hepatitis”. Currently an estimated 325 million people worldwide are living with chronic hepatitis B or hepatitis C virus infecti...
