Exploring the utilization of white spaces (vacant VHF and UHF TV channels) is a promising way to satisfy the rapidly growing radio frequency (RF) demand. Although a few white space exploration methods have been proposed in the past few years, they mainly focused on outdoor scenarios. In this paper, we propose a novel cost-efficient indoor white space exploration method by exploiting the location dependence...
Individual recognition is the technique which recognizes person's identity through his gait. Gait energy image (GEI) is a classical gait representation and it can be decomposed into structural part and detailed part. Then virtual gait energy image (VGEI) can be constructed in virtual space by integrating those two different parts. The generalized principal component analysis (GPCA) is applied to VGEI...
This paper introduces a novel pre-locating algorithm for rapid logo detection in unconstrained color images. This work is distinguished by two major contributions. The first is a new method of representation for logo called “spatial connected component descriptor” (SCCD) containing connected component (CC) prediction model and effective-CC pixel distribution histogram. The former represents combinations...
Location based services (LBS) are very abundant in our society, which focus on providing users navigation information to make the travel more convenient. With the rapid development of evolving mobile technologies (3G, Wi-Fi, and IPv6), large amounts of data (infotainment, et al.) transmission comes true, which makes the sole navigation information seems tedious. Ubiquitous Computing emphasizes the...
The rapid advances in wireless devices and positioning technologies boost various kinds of location-based services. Location-based push service plays an important role in the mobile environment as it foresees useful information to mobile users according to their current location, but the large number and continuous location changing of users make the system load heavy. This paper first proposes a...
Along with the rapid improvement of the test instruments capability and network technology, the resources sharing and collaborative work implementing in test system have been in front us. In order to solute these problems, a novel network test system based on web service (NTSWS) is presented. In this paper, we elaborate the architecture and working mechanisms of the NTSWS system. Then, the system...
This paper describes an application system process that is developed by combining the Delphi language with software engineering theory knowledge. It elaborates the whole process of designing in detail in the process of developing system, gives the chart of system function and partial source code, states the steps of system tests together with check and accept at last. The system is belongs to hydraulic...
Web has become the major tool of e-commerce for the last ten years and it requires Internet corporations to provide personalized services by tracking and analyzing users' visiting patterns. Web data analysis system (WDAS) is a necessary tool supporting the Web data mining and knowledge discovery (DM & KD) process. However, in the past, research on DM & KD always focused attention on algorithm...
Software metrics is one of the most active research areas of software engineering. In this paper, a process model for software process metrics is proposed, which defines the roles, activities and related supporting tools and methods for the implementation of software process metrics, and gives an emphasis on the description of the goals, tasks and methods for the activity of process data collection,...
