The processes and factors which affect shell growth repair in molluscs are poorly understood. In this study, the capabilities of marine gastropod Buccinum undatum were investigated experimentally by implementing laboratory-controlled mechanical damage to margin/lip. Three key factors, life stage (juvenile or adult), seawater temperature (5–15 °C) food availability (unfed, weekly, daily feeding)...
This paper addresses the problem of lip segmentation in color space, which is a crucial issue to the success of a lip-reading system. We present a new segmentation approach to lip contour extraction by taking account of the color difference between lip and skin in color space. Firstly, we obtain a lip segment sample via a color transformation sequence in 1976 CIELAB and LUX color spaces. Second...
A cross-sectional study was conducted to determine gender specific correlation between lip print, finger print and blood group among 120 adult clinical cases in a tertiary hospital Kathmandu. Lip prints were collected using lipstick cellophane sheet. Thumb commercially available ink pad white paper analyzed hand held magnifying lens. Blood noted at the time of recording thumb print. statistical...
The use of visual information from lip movements can improve the accuracy and robustness of a speech recognition system. Accurate extraction of visual features associated with the lips is thus very important. In this paper, we present a deformable model-based technique for lip contour extraction from color lip images. The geometric lip model we proposed is able to fit different lip shapes. Our ...
Lip contour detection and tracking is the most important pre-requisite for computerized speech reading. Several approaches have been proposed for lip tracking after lip contour is accurately initialized on first frame. Detection and tracking of the lip contour is an issue in speech reading. A relatively large class of lip reading algorithms are available based on lip contour analysis. In these ...
The purpose of this study was to determine the upper lip by Holdaway’s method in individuals with bimaxillary proclination and to find out correlations of skeletal convexity at point A & maxillary incisor inclination with upper lip inclination and upper lip strain. Lateral cephalograms of 100 patients (50 males and 50 females) exhibiting bimaxillary dental proclination were exposed in closed li...
سابقه و هدف: با توجه به افزایش تقاضا برای درمان های ارتودنسی در سالیان اخیر استفاده از دستگاههای فانکشنال گسترش فراوانی یافته است. از طرف دیگر بیشتر مطالعات موجود در مورد تغییرات متغیرهای اسکلتال و دنتال متعاقب استفاده از دستگاههای فانکشنال به بحث و بررسی پرداخته اند و تحقیقات کمتری در باره تغییرات متغیرهای بافت نرم صورت گرفته است، لذا با توجه به اهمیت موضوع، این تحقیق با هدف بررسی تغییرات متغی...
Background: Oral clefts are among the most common congenital anomalies. Infants with oral clefts often have other associated congenital defects, especially congenital heart defects. The reported incidences and the types of associated malformations and congenital heart defects vary between different studies. The purpose of this study was to assess the incidence of associated congenital heart def...
Cleft lip defects are usually regarded as a single entity, with the assumption that an accompanying cleft palate represents the more severe form. The authors linked data from the Medical Birth Registry of Norway with medical records from two centralized centers to provide a population-based data set. They assessed the distribution of cleft lip only and cleft lip with cleft palate by covariate. ...
