In this paper, we explore and discuss the data security issues in a real-time remote patient health monitoring system, called the Personal Health Data Management System (PHDMS). The health monitoring system examined for this study consists of multiple wireless sensors, central data coordinator called the Wireless Intelligent Personal Communication Node (W-iPCN), an Android smartphone, and a remotely...
Keyword spotting remains a challenge when applied to real-world environments with dramatically changing noise. In recent studies, audio-visual integration methods have demonstrated superiorities since visual speech is not influenced by acoustic noise. However, for visual speech recognition, individual utterance mannerisms can lead to confusion and false recognition. To solve this problem, a novel...
Present day ultrasonic signal processing applications such as medical imaging and non-destructive testing has stringent requirements on low cost and portability to provide high quality diagnostics and characterization at real-time pace. Advancements in the field of digital signal processing, embedded computing, and semiconductor technologies, have significantly assisted ultrasound researchers in the...
Many metric learning approaches neglect that the real world multi-class problems share strong visual similarities, which can be exploited by learning discriminative models. In this paper, a Two-level Multi-task Metric Learning (TMTL) method is presented to learn a distance measure from equivalence constraints. Multiple features are adopted to represent the image information and learn the distance...
Visual speech recognition also known as lipreading can improve robustness of automatic acoustic speech recognition especially under noisy environments. However, it remains a challenging topic considering the variety of speaking characteristics and confusion between visual speech features. In this paper, we propose an automatic lipreading method by using a new lip tracking method and multiple visual...
Automatic age estimation relying on human facial images is a key technology of many real-world applications, which is still a challenging task in the computer vision field. There are three cascade modules for facial age estimation: facial aging feature extraction, dimension reduction (or feature selection) and estimation method. Many existing literatures focus on the first or last module while for...
Although keyword spotting (KWS) technologies have been successfully applied to some applications, most KWS systems have a common problem of noise-robustness when applied to real-world environments. Audio-visual keyword spotting (AVKWS) using both acoustic and visual information is a solution to complementarily solve the problem. Most existing audio-visual speech recognition (AVSR) systems extract...
Keyword spotting (KWS) deals with the identification of keywords in unconstrained speech, which is a natural, straightforward and friendly way for human-robot interaction (HRI). Most keyword spotters have the common problem of noise-robustness when applied to real-world environment with dramatically changing noises. Since visual information won't be affected by the acoustic noise, it can be utilized...
Automatic recognition of spontaneous versus posed (SVP) facial expressions has received widespread attention in recent years for its potential applications in friendly human machine interface. Most existing works of SVP facial expression recognition extract geometry-based features which heavily rely on accurate detection and tracking of facial feature points. In this paper, a novel approach is proposed...
Smiles play an important role in face to face interaction which is a human-specific direct and naturally preeminent way of communication. People smile out of various reasons. Some smiles are spontaneous while some others are just posed. It is hard for human to catch such subtle differences between the two different smiles. In this paper, different algorithm combinations are tried to realize the deceit...
