In this paper, we present an image-based indoor positioning system for digital museum application using omniderectional images to which location information is embedded. By using robust image matching by PCA-SIFT, fast nearest neighbor search algorithm based Locaity Sensitive Hashing (LSH), and the confidence measure which takes into consideration of the location of the objects in the query image,...
In this demonstration, we present VisiAds, a vision-based online advertising platform which allows advertisers to bid on image content as opposed to text keywords. The demonstration shows an implementation of the platform designed specifically for mobile application scenarios. It can be used by advertisers to trigger and deliver multiple advertisements based on a query image captured from a consumer-grade...
In our previous result, a GPS-enabled (global positioning system) device is incorporated into visual surveillance to provide a novel visual tracking service. A person carried such device can be tracked not only on a digital map, but also in the real-time camera image. However, the approach relies on a calibration method with five calibration points for transforming a GPS coordinate into an image coordinate...
