GSM-based positioning technology is more suitable for navigation than GPS in urban, indoor and even underground areas. However, it cannot be used for automotive navigation due to its large positioning error (more than 100m). This paper presents an approach utilizing fractal analysis and wavelet transform to enhance GSM-based positioning accuracy. Fractal theory and analysis is introduced into the...
This paper presents a reconfigurable entropy encoder for real time adaptation of multi-standard compressed video stream. The proposed architecture is based on partial and dynamic reconfiguration. Static and dynamic wrappers are defined to encapsulate different types of entropy coders. A partitioning of reconfigurable area is also presented aiming at the optimization of reconfiguration overhead. The...
Hybrid architecture of content delivery network (CDN) and peer-to-peer (P2P) is a promising network technology enabling effective real-time streaming services. It complements the advantages of quality control and reliability in CDN and the scalability in the P2P system. With real-time streaming services, however, high connection setup and media delivery latency are becoming the critical issues to...
Online grocery shopping becomes more and more popular in recent years. To facilitate the purchase process, many online stores provide a shopping recommendation system for their consumers. So far, the generic recommendation systems mainly consider preferences of a consumer based on his/her purchase histories. Nevertheless, it is noted that there is nothing to do with the right timing to purchase a...
Nowadays, mobile phones are used everywhere and every time in our daily life ranging from communication, entertainment to health and wellness applications. For managing incontinence among dementia subjects at nursing home, it is difficult to have timely diaper change with regular scheduled checks. Delays in diaper change results serious implications in economic, social and clinical aspects. So we...
Technology is a never ending process. To be able to design a product using the current technology that will be beneficial to the lives of others is a huge contribution to the community. This paper presents the design and implementation of a low cost but yet flexible and secure cell phone based home automation system. The design is based on a stand alone Arduino BT board and the home appliances are...
Super-resolution image reconstruction is an important technology in many image processing areas such as image sensing, medical imaging, satellite imaging, and television signal conversion. It is also a key word of a recent consumer HDTV set that utilizes the CELL processor. Among various super-resolution methods, the learning-based method is one of the most promising solutions. The problem of the...
The articulated body tracking is challenging area in HCI (Human Computer Interaction) community. In this paper, we propose a method for robust articulated body tracker using dense disparity maps, which reduce the searching space, derived from stereo image sequences. To track an articulated body we first model the human body as MRF networks with tree structured graph, and belief propagation(BP) is...
The wireless network environment in the future is going to include various heterogeneous wireless networks. In a heterogeneous wireless network environment, vertical handoff processes caused by the movement of users are inevitable. However, the research related to how to achieve seamless vertical handoff and improve QoS guarantees in today's heterogeneous wireless networks is still something to work...
This paper evaluates the interference effect on the Ultra-wideband (UWB) devices with Detect and Avoid (DAA) function on the WiMAX system. For this, an analytic model based on the Monte-Carlo method is proposed and we simulate about some scenario using the model. The result shows that the DAA function of UWB device can reduce the interference probability and this probability depends on the cell radius...
In this paper, we propose an embedded lane departure warning system that is composed of a robust control flow and a well-designed lane detection algorithm. The lane detection algorithm is designed based on a peak finding method to accommodate various lighting conditions, and a spatiotemporal mechanism using the detected lanes is proposed to generate appropriate warning signals. The entire system has...
Field service is a core component in the value proposition that many organizations offer their customers. Field service technicians often provide critical on-site support, which is one of the few face-to-face, post-sale interactions between manufacture/provider and end-user. This valuable interaction not only provides technical supports, but also presents an excellent opportunity to build and maintain...

This presentation discusses the drivers for consumer digital storage, the different mobile and static usage models for digital storage in consumer devices and the resulting consumer storage hierarchy. Important characteristics of consumer storage devices are shown and guidelines are given for how digital storage should be designed in consumer devices. Demand for higher resolution content and for capturing...
Cloud computing refers to clusters of distributed computers that provide applications as services and on-demand resources over Internet. Theoretically, such consolidated resource enhances the energy efficiency of both clients and servers. However, this paper presents that cloud computing is a panacea for enhancing energy efficiency only under some certain conditions. The computing resources of cloud...

Heading the R&D team, he is actively involved in the overall project planning and execution, from initial conceptualization design work to registration of product patents. With his capabilities in firmware and software architectures, Mr Poo plays a crucial role in identifying and adopting emerging technologies...
Variable length coding (VLC) is a widely used technique in digital video compression systems. It is known for its efficient compression, but is susceptible to noisy environments. Due to the increased demand for multimedia systems to be portable, power consumption and power saving become important issues. Current ITU H.263+ and ISO MPEG-4 standards have used reversible variable length coding (RVLC)...
With the arrival of High Definition Television (HDTV), the TV technology is heading towards 3DTV. Evolution of 3DTV requires the facility of capturing and analyzing the multi-view images and compressing and transmitting massive volume of data through the communication channel. The most sever issue in 3D shape extraction is the roughness of the surfaces. Image focusing is a dominant method of reconstructing...
