Indoor localization is an important primitive that can enable many ubiquitous computing applications. This paper improves the scheme of landmark and inertial navigation through crowd sensing to address reliable and accurate indoor localization. The location of landmark can calibrate the location of user and inertial navigation can optimize the location of landmark in turn. In this work, we define...
Mapping facial tracking data to avatars is very challenging and time consuming, where a simple, yet efficient approach is strongly required. State-of-the-art methods are either vulnerable to noise or heavily reliant on complicated sensor devices. To deal with the noisy data, and without using a motion capture device, we present a novel vision-based facial expression animation framework by applying...
With the rapid advancement of hardware efficiency in recent years, computation power has significantly improved, increasing the speed and depths of the game tree search in computer chess programs. However, to satisfy the need of increasing search depth, the investment in hardware is no longer personally affordable. Thus, another method must be found in addition to improving the efficiency of hardware...
With the initial completion of Human Genome Project, the post-genomic era is coming. Although the genome map of human has been decoded, the roles that each segment of sequences acts are not totally discovered. On the other hand, with the rapid expansion of sequence information, the issues of data compilation and data storage are increasingly important. Recently, a “Web-based Human Genome Database...
In the past, the utilization of the limb prosthesis has improved the daily life of amputees or patients with movement disorders. However, a leg-amputee has to take a series of training after wearing a limb prosthesis, and the training results determine whether a patient can use the limb prosthesis correctly in her/his daily life. This work proposes a prosthesis training system to allow the amputees...
The electrocardiogram is widely used for diagnosis of heart diseases. Several methods have been developed for ECG enhancement. This work presents a new ECG enhancement method for QRS complex detection. The moving average and cubic splines are successfully applied to detect the QRS complex through experiments on the MIT-BIH databases. The results show that the proposed method achieves good detection...
Intrusion detection system (IDS) is a security layer that is used to discover ongoing intrusive attacks and anomaly activities in information systems and is usually working in a dynamically changing environment. Although increasing IDSs are developed in the literature, network security administrators are faced with the task of analyzing enormous alerts produced from the analysis of different event...
Recent researches indicated that students' ability to construct evidence based explanations in classrooms through scientific inquiry is critical to successful science education. Structured argumentation support environments have been built and used in scientific discourse in the literature. To the best our knowledge, no research work in the literature addressed the issue of automatically assessing...
This research aims at developing a practical content-based video copy detection scheme, which employs an efficient and effective content matching approach to help determine whether an investigated video is a duplicated copy and may infringe the copyright. In the proposed scheme, the key frames of videos are first retrieved and the methods of Vector Quantization (VQ) and singular value decomposition...
