HeadLock : wide-range head pose estimation for low resolution video
… focuses on data mining technologies to extract head pose information from low resolution video recordings. Head pose, as an approximation of gaze direction, is a key indicator of human behavior and interaction. Extracting head pose information from video recordings is a labor intensive endeavor …

Social Interaction Inference and Group Emergent Leadership Detection Using Head Pose
… to address this challenge by different proposed models and compact descriptors encoding the consistency between people's spatial-temporal body features or their overall activities. Among all human body features, the head pose provides a distinct description of an individual's attention and …

Multiple Tasks are Better than One: Multi-task Learning and Feature Selection for Head Pose Estimation, Action Recognition and Event Detection
… of well-defined illumination, background, and pose of the object relative to the camera. Machine Learning (ML) and Computer Vision (CV) have been put together during the development of computer vision in the past decade. Nowadays, machine learning is considered as a powerful tool to solve many …

Face Recognition in Unconstrained Conditions: Improving Face Alignment and Constructing a Pose-Invariant Compact Biometric Template
… unconstrained conditions regarding variations in pose, illumination, and occlusion. Existing solutions tackle the unconstrained face recognition problem in two ways: (i) controlling the variations of the input to the recognition system, and (ii) improving the robustness of the recognition system …

Embedded Eye-Gaze Tracking On Mobile Devices
… gaze can be determined through both their head pose as well as the orientation of the eye relative to the head. To meet the challenges outlined a geometric approach is taken where a new model for each is introduced that by design are completely synchronised through a common origin. First, a …

Adapting Single-View View Synthesis with Multiplane Images for 3D Video Chat
… which, in our case, would match with the head pose of the watcher in the opposite, concurrent video frame. We discuss that our pipeline, when implemented in real-time, would allow both video chat participants to unravel occluded scene content and "peer into" each other's dynamic video …

Joint Face Detection and Tracking in Three-Dimensional Space
… low-resolution faces, as well as lighting and head-pose variations. These difficulties can often be successfully addressed by additional information in the form of multicamera input to reduce spatial uncertainty in the scene of interest. The system described in this dissertation takes such …

Autonomous Robotic Escort Incorporating Motion Prediction with Human Intention
… destination successfully and efficiently. The proposed technique uses accurate path prediction incorporating human intention to locate the robot in front of the human while walking. Human intention is inferred by the head pose, an effective past-proven implicit indicator of intention, and fused …

Understanding Human Perception Through MooneyFaces
… can still extract information about identity, pose, and more. Most current deep learning computer vision models perform well with standard face images, but they struggle with stimuli which differ from their training data, like Mooney faces. What makes human perception so comparatively robust? …

Facial Expression Recognition: Fusion of A Human Vision System Model and A statistical framework
… in the physiognomy of faces with respect to head pose, environment illumination and person-identity. Even assuming illumination and pose invariance in face images, recognition of facial expressions from novel persons always remains an interesting and also challenging problem. With the goal of …

Real-time 3D face localization and verification
… consists of three parts: face detection, head pose estimation, and face verification. Face detection is performed using a standard detection framework which we significantly improve by leveraging depth information. To estimate the pose of the detected face, we developed a technique that …

An implementation of face-to-face grounding in an embodied conversational agent
… a vision system, based on a stereo-camera head-pose tracker and using a recently proposed method for head-nod detection, that can robustly and accurately identify head nods and gaze state.

Where are they looking?
… computer vision community. In this thesis, we propose a deep neural network-based approach for gaze-following and a new benchmark dataset, GazeFollow, for thorough evaluation. Given an image and the location of a head, our approach follows the gaze of the person and identifies the object being …
