Delineating the Reach of Internet Intermediaries’ Content Blocking – “ccTLD Blocking”, “Strict Geo-location Blocking” or a “Country Lens Approach”?

open access: yesSCRIPTed: A Journal of Law, Technology & Society, 2014
There is a prominent trend of legal actions being taken against globally active Internet intermediaries. This article discusses the extent to which Internet intermediaries should be required to block or remove third-party content, and places emphasis on ...

PRICISE TARGET GEOLOCATION BASED ON INTEGERATION OF THERMAL VIDEO IMAGERY AND RTK GPS IN UAVS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
There are an increasingly large number of uses for Unmanned Aerial Vehicles (UAVs) from surveillance, mapping and target geolocation. However, most of commercial UAVs are equipped with low-cost navigation sensors such as C/A code GPS and a low-cost IMU ...

A Two-Stage Aerial Target Localization Method Using Time-Difference-of-Arrival Measurements with the Minimum Number of Radars

open access: yesRemote Sensing, 2023
Distributed radar systems promise to significantly enhance target localization by virtue of the superiority of multi-view observations from widely separated radars, compared to their monostatic counterparts. Nevertheless, when the radar number is limited,

Instataneous geo-location of multiple targets from monocular airborne video

open access: yes2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
We propose a robust and accurate method for multi-target geo-localization from airborne video. The difference between our approach and other approaches in the literature is fourfold: 1) it does not require gimbal control of the camera or any particular path planning control for the UAV; 2) it can instantaneously geo-locate multiple targets even if they

Two (or three) is one too many : testing the flexibility of contextual cueing with multiple target locations [PDF]

open access: yes, 2011
Visual search for a target object is facilitated when the object is repeatedly presented within an invariant context of surrounding items ("contextual cueing"; Chun & Jiang, Cognitive Psychology, 36, 28-71, 1998).
