This paper presents a method of gender classification by integrating facial, hairstyle, and clothing images. Initially, input images are separated into facial, hairstyle and clothing regions, and independently learned PCAs and GMMs based on thousands of sample images are applied to each region. The classification results are then integrated into a single(More)
This paper proposes a novel on-demand multipath routing protocol for a mobile ad hoc network. By applying a newly developed route update procedure with combined metrics of delay, hop count and disjointness, each intermediate node deliberately selects multipath candidates while contributing to suppression of unnecessary routing packets. Extension of(More)
Most network applications nowadays are related to the distribution of contents from a source to a number of users. Several developments such as CDN and P2P networking have been used to provide access to contents at the network edges. However, they have no ability to leverage caching at the network level and still rely on a host-based communication model.(More)
This thesis addresses the problem of the design and implementation of a scalable system for interactive multimedia streaming on the Internet. We show that a combination of Content Distribution Networks (CDNs) and Peer-to-Peer (P2P) networking techniques can be used to build an efficient and scalable architecture that offers low-cost streaming services. The(More)
The growing popularity of mobile data communication has been leading a growing lack of radio resource on a cellular network. Therefore, to avoid the data traffic from exceeding the capacity limit of a cellular base station (BS), cellular operators have been trying to install cellular femto cells (local BSs) or wireless LAN access points (APs) in(More)
This paper presents a novel approach for efficient tree construction in ALM (application layer multicast) using layered video coding. This system is suitable for the users in heterogeneous environment such as xDSL and CATV, where upload and download speeds are different. We point out some problems in these environment of the ALM and show their solutions at(More)
