This paper addresses the problem of automated extraction of constant valued elevation curves (isocontours) from 2dimensional (2D) images of historical maps. We present a new isocontour extraction method that can operate in a semi automatic or fully automatic mode. The novelty of the work is in developing an isocontour extraction technique for historical map analysis that is unique in the GIS ap...

Dilemmas accompanying esthetic zone implants frequently involve a dehiscence type defect of the midfacial tissues. The challenge to the surgical-restorative implant team is to understand the etiology associated with such defects and the treatment options that can be offered lending to predictable outcomes. Etiologic factors are: 1) poor implant spatial positioning; 2) incorrect abutment contour...

INTRODUCTION Breast reconstruction with autologous tissue transfer is now a standard operation, but abnormalities of the abdominal wall contour represent a complication which has led surgeons to invent techniques to minimize the morbidity of the donor site. CASE PRESENTATION We report the case of a woman who had bilateral transverse rectus abdominis myocutaneous flap (TRAM-flap) breast recons...

Image segmentation is a fundamental image preparing approach this is utilized to research what is the component of the image graph. Image segmentation is utilized to part an image into various "huge" segments. The paper basically offers with surface segmentation while actualities pixel end up noticeably given mixed and blended error diminished so it could be one of the issues to manage likewise...

BACKGROUND Large defects arising from extirpation surgery of buttock sarcomas requiring adjuvant radiotherapy are best closed with flap surgery. The traditional solutions are derived from an approach to pressure sores, which were designed for the ischial, sacral, or trochanteric areas, and have now been adapted for true buttock defects. This invariably destroys the esthetics of the buttock. We ...

patients and methods previously recorded data of 231 patients who underwent surgical closure of vsd between january 2009 and january 2012 at the rajaie cardiovascular medical and research center were retrospectively reviewed. vsd surgical repair was performed using continues suturing technique in group a patients (n = 163, 70.6%) and interrupted suturing technique in group b patients (n = 68, 2...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...
