Identifying facial landmarks, action units and emotions using deep networks
… Convolutional Neural Networks (CNNs) to predict facial landmarks, facial action units and emotions and to study the results of intermediate experiments while doing so. Learning the different features of facial images has always been a difficult task and primarily involves using hand-crafted …

Landmark localisation in 3D face data
… In this thesis, an investigation to localise facial landmarks from 3D images is presented, without using any assumption concerning facial pose. In particular, this research devises new surface descriptors, which are derived from either unstructured face data, or a radial basis function (RBF) …

Three-dimensional outcomes of twin-block appliance treatment and the influence of the postured wax bite
… the TBA treatment outcome on the soft tissue facial profile volumetric and linear landmark changes from the Postured Wax Bite (PWB). 3 To identify if there is any association between certain soft tissue landmark variables and successful treatment outcome of the TBA as measured by the reduction …

Learning to localize landmarks
… single point. We refer to these small objects as landmarks in addition to the more common usage of the term to refer to the anatomical or facial landmarks. Landmark localization refers to the detection of one or more such landmarks in an image. In this dissertation, we describe methods for …

Using Facemesh in MIT App Inventor to Empower Students to Apply Artificial Intelligence
… intelligence (AI) comes in the form of facial filters that are readily accessible on Instagram and Snapchat. These filters allow users to seemingly transform themselves into animals, put on pieces of clothing, or try out new “looks”. Accompanying active usage, however, is often lack of …

Fast head profile estimation using curvature, derivatives and deep learning methods
… and annotated with anthropometric cranio-facial landmarks, and a novel method of automatically improving the accuracy of the landmark positions was developed using ideas based on the curvature of a plane curve. The features identified here were extracted from the new head profile contour …

Pattern recognition to detect fetal alchohol syndrome using stereo facial images
… and neurodevelopment abnormalities together with facial malformations. The main facial features which best distinguish children with and without FAS are smooth philtrum, thin upper lip and short palpebral fissures. Diagnosis of the facial phenotype associated with FAS can be done using methods …

Human metrology for person classification and recognition
… based solely on metrological information from facial landmarks is developed. The performance of the proposed metrology-based method is compared with that of a state-of-the-art appearance-based method for gender classification. Results on several face databases show that the metrology-based …

An Investigation into the Performance of Ethnicity Verification Between Humans and Machine Learning Algorithms
… a significant human characteristic and applying facial image data for the discrimination of ethnicity is integral to face-related biometric systems. Given the diversity in the application of ethnicity-specific information such as face recognition and iris recognition, and the availability of …

Towards Robust And Practical Neural Video-Conferencing
… sparse representations of each frame such as facial landmark information. However, these approaches produce poor reconstructions in scenarios with major movement or occlusions over the course of a call, and do not scale to higher resolutions. To cope with packet loss, most systems use …

Are post-treatment orthognathic patients attractive? A three-dimensional study
… objective of orthognathic surgery is to improve facial aesthetics and function to an acceptable standard and to the patient’s satisfaction. Exactly what constitutes an acceptable standard of facial aesthetics to a patient has been the topic of numerous studies and yet has so far remained elusive. …

Facial anthropometry as an evidential tool in forensic image comparison
… confirming the identity of individuals based on facial descriptions and for use as a comparison tool in forensic identification. Pilot Laboratory Study: A number of different techniques are employed in facial image comparison of living persons. In this study, the effect of rotation on angles and …
