In this paper, we introduce a novel touristic trip suggestion system to facilitate the traveling of mobile users in a given city. Given the current user location and his touristic destination, our system can suggest a shortest trip path that visits as many popular landmarks as possible. To this end, we collect geographical tagged photos from Flickr [1] and Panoramio [2] photo sharing websites. Then...
State-of-the-art mobile visual search systems put emphasis on developing compact visual descriptors [4][6], which enables low bit rate wireless transmission instead of delivering an entire query image. In this paper, we address the orderless nature of the transmission set of query descriptors . We propose to adapt the orders of local descriptors in transmission, which subsequently yields more consistent...
We present a low bit rate vocabulary coding scheme in the context of mobile landmark search. Our scheme exploits location cues to boost a compact subset of visual vocabulary, which is discriminative for visual search and incurs low bit rate query for efficient upstream wireless transmission. To validate the coding scheme, we have developed mobile landmark search prototype systems within typical areas...
Combined forecast method is an important research direction in forecast field. The relevant research has shown many advantages of combined forecast. However, how to acquire efficiently the weight coefficients of combined forecast method to get the predicted value with minimum error is often hard to solve efficiently. Because the adaptive parameter real-coded genetic algorithm (APRGA) not only has...
In this paper, a low complexity cell search algorithm (ML-ACL algorithm) for mobile OFDMA systems is proposed, with IEEE 802.16e as the example. The main problem on cell search is the huge computational complexity due to the long pseudo-noise (PN) series. Based on the maximum-likelihood (ML) detection theory, the ML-ACL algorithm uses an adaptive correlation length (ACL) to greatly reduce computational...
This paper demonstrates the design and implementation of a real-time wireless physiological monitoring system for nursing centers, whose function is to monitor online the physiological status of aged patients via wireless communication channel and wired local area network. The collected data, such as body temperature, blood pressure, and heart rate, can then be stored in the computer of a network...
