Robust appearance based sign language recognition
In this work, we introduce a robust appearance-based sign language recognition system which is derived from a large vocabulary speech recognition system. The system employs a large variety of methods known from automatic speech recognition research for the modeling of temporal and language specific …

Appearance Based Stage Recognition of Drosophila Embryos
… throughput embryo images. Automatic recognition based on the appearances of embryos is becoming a more desirable scheme. This problem, however, is very challenging due to severe variations of illumination and gene expressions. In this research thesis, we propose an appearance based recognition …

Appearance based object recognition using independent component analysis
… years there has been a renewed interest in appearance based 3-dimensional object recognition. All possible views of an object define its workspace, known as visual workspace. This workspace is coarsely sampled and projected onto a lower-dimensional space and represented as workspace …

The Effects of Appearance-Based Reality Shows on Body Image
… that females who are more likely to make appearance comparisons with thin images in the media often experience negative outcomes. Research has shown that increased exposure to thin images in the media is associated with higher body dissatisfaction and eating disorder features. A form of …

TabletGaze: Dataset and Algorithm for Unconstrained Appearance-based Gaze Estimation in Mobile Tablets
In this thesis, we study gaze estimation on tablets. Our key design goal is uncalibrated gaze estimation using the front-facing camera during natural use of tablets, where the posture and method of holding the tablet is not constrained. We collected the first large unconstrained gaze dataset of …

Appearance-based material classification after occlusion removal for operation-level construction progress monitoring
… sites, has significantly interest popularity of appearance-based methods for automated construction progress using site photographs monitoring. These methods, however, face a number of technical challenges that limit their applicability including low spatial resolution of images, and static and …

Appearance based modeling and learning of the human face with application to biometrics
… face processing techniques into two classes: appearance-based approaches that model facial appearance holistically, and feature-based approaches, which rely on the localization of facial feature points. In this dissertation we argue that appearance-based approaches are well suited for various …

Investigating the Role of Appearance-Based Factors in Predicting Sunbathing and Tanning Salon Use
… Psychosocial models of UV exposure are often based on theories of health behavior, but theory from the body image field can be useful in understanding motives to UV expose as well. The current study examines models that prospectively predict sunbathing and indoor tanning behaviors using …

Collaborative Appearance-Based Place Recognition and Improving Place Recognition Using Detection of Dynamic Objects
… makes contributions to the problem of Long-Term Appearance-Based Place Recognition. We present a framework for place recognition in a collaborative scheme and a method to reduce the impact of dynamic objects on place representations. We demonstrate our findings using a state-of-the-art place …

The comparative study of model-based and appearance based gait recognition for leave bag behind
… method used capable of identifying the subject based on their gait and can be presented as the most probable subject as a strong evidence for criminal identification. This research limited to leave the bag behind detection on gait recognition. In this research, the analysis performed using two …

Robust Feature Tracking in Image Sequences Using View Geometric Constraints
… tracking has been performed with a variety of appearance-based comparison methods. The most common methods analyze intensity values of local pixels and subsequently attempt to match them to the most similar region in the following frame. This standard, though sometimes effective, lacks …

Improving robustness of gait recognition based on deep learning
… One category of gait recognition methods is appearance-based algorithms, which usually extracts human silhouettes as the initial input feature and achieves high recognition rates. However, the silhouette-based feature is easily affected by the view, clothing, bag, and other external …

Enhancing gait recognition with 3D markerless motion capture
… state-of-the-art gait recognition systems use appearance-based methods which are fast and capable of high performance on gait datasets. With the emergence of deep learning the focus of appearance-based methods has shifted, from the development of suitable gait representations to the …

"The Only Way I Was Going to Be Lovable." A Grounded Theory of Young People's Experiences of Body Dysmorphic Disorder.
… with perceived defects or flaws in one’s appearance. BDD most typically emerges in adolescence (Gunstad & Phillips, 2003; Phillips, Menard & Fay, 2006) and is estimated to affect 2.2% of the UK adolescent population (Veale, Gledhill, Christodoulou, & Hodsoll 2016). There is a dearth of …

COMPOSITE KERNEL FEATURE ANALYSIS FOR CANCER CLASSIFICATION
… images by effectively incorporating an appearance-based object recognition approaches into a model-based CAD scheme. Our studies are focused in developing a fast kernel feature analysis that can efficiently differentiate polyps from false positives and thus improve the detection …

Modeling of image variability for recognition
… recognition problems using the paradigm of appearance-based recognition.We first discuss linear models of variability and relate them to the use of Gaussian distributions. This allows us to use well-understood estimation methods to determine the vectors representing the variability.We also …
