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, ...

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...

synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...

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 palmari...

For many years, speech has been the most natural and efficient means of information exchange for human beings. With the advancement of technology and the prevalence of computer usage, the design and production of speech recognition systems have been considered by researchers. Among this, lip-reading techniques encountered with many challenges for speech recognition, that one of the challenges b...

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 ...

nevoid basal cell carcinoma syndrome (nbccs), also known as gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms . the estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. main clinical manifestations include multiple basal cell carcinomas (bccs), odontogenic keratocysts o...

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 ...
