Lip tracking has played a significant role in a lip reading system. In this paper, we present a local region based approach to lip tracking, which consists of two phases: (i) lip contour extraction for the first lip frame, and followed by (ii) lip tracking in the subsequent lip frames. Initially, we construct a localized color active color model provided that the foreground and background regio...

Metrology applications commonly require non-contact, capacitive sensors for displacement measurements due to their nanometer resolution. In some metrology applications, for example, the measurement of roundness and spindle error motion, the displacements of stationary and rotating cylindrical artifacts are measured. Error from using a conventionally calibrated sensor with a non-flat (e.g., cyli...

The objective was to explore quantitative methods for the measurement of lip mobility and lip force and to relate these to qualitative assessments of lip function. Fifty healthy adults (mean age 45 years) and 23 adults with diagnoses affecting the facial muscles (mean age 37 years) participated in the study. Diagnoses were Möbius syndrome (n=5), Facioscapulohumeral muscular dystrophy (n=6) and ...

introduction: advanced lip carcinomas can invade adjacent structures. performing surgery for these cancers will lead to defects in this anatomically and functionally important area and will cause post-op difficulties such as drooling, speech alterations and aesthetic considerations, if not properly managed. case report: in this study, we will introduce a radial forearm free flap with palmaris l...

OBJECTIVE A quantitative comparison of immediate and long-term results of surgical correction of the senile upper lip using lip advancement and lip lift. METHODS Retrospective review of 30 patients who underwent senile upper lip repair, including lip advancement or lip lift. Digital image analysis was used to standardize each patient's preoperative and postoperative photographs for accurate, ...

The Triassic-Jurassic boundary (Tr-J; ∼201 Ma) is marked by a doubling in the concentration of atmospheric CO2, rising temperatures, and ecosystem instability. This appears to have been driven by a major perturbation in the global carbon cycle due to massive volcanism in the Central Atlantic Magmatic Province. It is hypothesized that this volcanism also likely delivered sulphur dioxide (SO2) to...

Spatial downsampling layers are favored in convolutional neural networks (CNNs) to downscale feature maps for larger receptive fields and less memory consumption. However, visual recognition tasks, these might lose discriminative details due improper pooling strategies. In this paper, we present a unified framework (LAN) over the common (e.g., average pooling, max strided convolution) from view...

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...

This paper presents a new methodology to improve roundness process of the centreless grinding based on classic stability diagrams and relative rounding mechanism. study has shown that it is not always convenient have fixed setup angle. Based simulation results, suggested consider raw workpiece profile before selecting these parameters accordingly type error (odd or even lobed). It was found cha...
