Accurate Location of Façades of Interest in Street View Panoramic Sequences
2015 Edition, August 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Geo-spatial queries, i.e., Queries that combine location data with other kinds of input, have taken huge importance in the last generation of search engines. The success of a geo-spatial search depends on the quality of the positioning information provided,...

Piecewise planar city 3D modeling from street view panoramic sequences
2009 Edition, June 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

City environments often lack textured areas, contain repetitive structures, strong lighting changes and therefore are very difficult for standard 3D modeling pipelines. We present a novel unified framework for creating 3D city models which overcomes these difficulties by exploiting image...

PosPush: A Highly Accurate Location-Based Information Delivery System
2009 Edition, October 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper proposes PosPush, a highly accurate location based information delivery system, which utilizes the high resolution 3D locations obtained from ultrasonic positioning devices to efficiently deliver the location based information to users. This system is designed...

Accurate Location Tracking from CSI-based Passive Device-free Probabilistic Fingerprinting
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The research on indoor localization has received great interest in recent years. This has been fuelled by the ubiquitous distribution of electronic devices equipped with a radio frequency (RF) interface. Analyzing the signal fluctuation on the RF-interface can, for instance,...

Preserving Location Privacy of Connected Vehicles With Highly Accurate Location Updates
2017 Edition, Volume 21, March 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Connected vehicles are at risk of exposing their location history when using potentially untrusted location-based services (LBSs) in the driving process. We propose a method called mutually obfuscating paths (MOP) that enables vehicles to provide highly accurate...

Detecting repetitive elements with accurate locations and shapes from urban façade
2015 Edition, September 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper proposes a novel algorithm to automatically detect the repetitive elements with accurate shapes, locations and sizes from single façade image. Unlike other algorithms, our algorithm is not entirely dependent on the extracted feature points, edges and symmetric...

Messages in a Concealed Bottle: Achieving Query Content Privacy with Accurate Location-Based Services
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Query privacy has led to a serious concern for location-based services (LBSs). Existing mainstream schemes preserve query privacy by either introducing a third party or degrading the accuracy of LBS. To address these deficiencies, we propose a scheme named the content sealed bottle...

Messages in a Concealed Bottle: Achieving Query Content Privacy With Accurate Location-Based Services
2018 Edition, Volume 67, August 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Query privacy has led to a serious concern for location-based services (LBSs). Existing mainstream schemes preserve query privacy by either introducing a third party or degrading the accuracy of LBS. To address these deficiencies, we propose a scheme named the content sealed bottle...

Accurate Indoor Location Tracking Exploiting Ultrasonic Reflections
2016 Edition, Volume 16, December 15, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Time difference of arrivals) (TDoA)-based location tracking systems using RF and ultrasonic signals often give unacceptable errors due to the line-of-sight limitation of the ultrasonic signal. To overcome this limitation, many researchers have devoted their efforts using...

Accurate location of inter-circuit faults on double-circuit transmission lines based on sparse wide-area voltage measurements
2017 Edition, July 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Inter-circuit fault is a type of fault in which phases from two or more circuits at a single geographical location are connected. This type of fault is more likely to occur on a double-circuit transmission line located on a single tower structure. This paper proposes a...
