Accurate boundary determination and segmentation of an object interest in image is a difficult task. In this paper, we propose new model which improves the old selective Rada et al. [23] by combining two penalization fitting terms. To better deal with oscillatory boundaries, H^1 weighted length term L^2 Lebesgue measure have been employed as terms, whereas terms consist region-based area term. ...

In this paper we show that there are infinitely many pairs of integer isosceles triangles and integer parallelograms with a common (integral) area and common perimeter. We also show that there are infinitely many Heron triangles and integer rhombuses with common area and common perimeter. As a corollary, we show there does not exist any Heron triangle and integer square which have a common area...

Introduction With the advancement in imaging technology, 3D dental computed tomography plays a very significant role in orthodontic treatment and diagnosis. Aim To evaluate dental crowding in relation to the mesiodistal crown widths and arch dimensions and also to determine the differences of dental crowding among males and females, in Southern Indian population. Materials and Methods A tot...

The study objective was to examine precision in wound measurement using a recently Food and Drug Administration-approved Scout (WoundVision, LLC, Indianapolis, Indiana) device to measure wound length (L) and width (W). Wound perimeter and a ruler measurement of L and W were also made. Images of 40 actual patient wounds were measured using the Scout device. All 3 techniques (length, width, perim...

The current WRF-Fire model starts the fire from a given ignition point at a given time. We want to start the model from a given fire perimeter at a given time instead. However, the fuel balance and the state of the atmosphere depend on the history of the fire. The purpose of this work is to create an approximate artificial history of the fire based on the given fire perimeter and time and an ap...

We discuss the asymptotic behaviour of models of lattice polygons, mainly on the square lattice. In particular, we focus on limiting area laws in the uniform perimeter ensemble where, for fixed perimeter, each polygon of a given area occurs with the same probability. We relate limit distributions to the scaling behaviour of the associated perimeter and area generating functions, thereby providi...
