With the fast evolution of computer technology, the service from search engines has been providing more and more convenience to mobile terminals. However, traditional key-word search engines have their own deficiency on certain areas which take geographical factors into account. To overcome this deficiency, this paper discusses about another new type of search, location-based search. After analyzing...
Collaborative filtering recommendation algorithm is currently the most widely used personalized recommendation algorithm. Sparsity problem of user rating data led to the recommendation quality of traditional collaborative filtering algorithms are far from ideal. To solve the problem, the paper first cloud model and project characteristic attributes to calculate the similarity between the project has...
The paper designs the system of real-time streaming media transmission based on multiple 3G-card in the mobile environment especially for news workers to report news events quickly and duly. The paper introduces the system framework including 3 big modules: capturing and transportation subsystem, multiple 3G cards controlling subsystem and media receiving subsystem. Among them transmission and 3G...
Because of the best-effort characteristics of the Internet, it is important to suppress the degradation of communication quality on the receiving side caused by data packet loss and errors as well as the limited network bandwidth. This paper focus on MPEG transmission over the Internet and Differentiated Services architecture established to improve Quality of Services (QoS). Packets are classified...
A real-time eye tracking method was introduced. The method integrates several algorithms such as AdaBoost, optical flow, and Camshift. First, lighting condition was standardized, and the camera was placed below face. Second, the nostril tracking points were localized and taken as reference points. Third, the Camshift algorithm and Lucas-Kanade optical flow algorithm were respectively utilized to track...
The high-speed connection of 3G network has transferred cell-phone applications’ bottleneck from network speed to both the performance of hardware and software and the presentational layer of applications. The 3D visualization on search results for mobile search client can meet the needs of 3G new business. And this technology can be widely used in the areas such as product display, advertising, real...
