Photo-sharing websites allows people to display their experiences on the Web through rich media data such as photos and videos. These photos contain spatial context in terms of latitude and longitude where the photo was taken. The geotagged photos disclose much information about people travel behavior and tourist density. As web-based and mobile-based technologies advance, geo-tagged photos are...

It is very attractive but technically very challenging if the user can retrieve photos from a huge collection using high-level personal queries (e.q. ”Uncle Bill’s House”). This paper proposes a set of approaches to achieve the goal assuming only 30% of the photos are annotated by sparse and spontaneously spoken descriptions when the photos are taken. We fuse the visual features (visual words p...

In this paper, we describe a novel application focus for the web2.0 paradigm of user generated mashups of geo-tagged photos, Here we are interested in photos captured by multiple participants (via their mobile phones) at a community event. Typically, current approaches focus on the production of a digital artefact, viewable on a web page, which supports a post-event reviewing activity, e.g. ena...

Commercial systems such as Flickr display interesting photos from their collection as an interaction mechanism for sampling the collection. It purely relies on social activity analysis for determining the notion of interestingness. We propose an alternative technique based on content analysis for finding interesting photos in a collection. We use a combination of visual attention models and an ...

A variety of forensic methods have been developed to identify falsified photos, each unified by the ability to estimate and detect properties of a photo that are perturbed by forgery. There exist, however, many photos in which the required properties cannot be estimated. We present an approach to detect forgery in these photos. We use this approach to detect physically inconsistent shadows and ...

PhotoStand enables the use of a map query interface to retrieve news photos associated with news articles that are in turn associated with the principal locations that they mention collected as a result of monitoring the output of over 10,000 RSS news feeds, made available within minutes of publication, and stored in a PostgreSQL database. The news photos are ranked according to their relevance...

Temporal information has been regarded as a key vehicle for sorting and grouping home photos into albums associated with events. While time-based browsing might be adequate for relatively small photo collection, query and retrieval would be very useful to find relevant photos of an event in large collection. In this paper, we propose the use of temporal events for organizing and representing ho...

We present a novel interaction technique that helps to make printed information more accessible to those with low or no textual literacy skills. AudioCanvas allows cameraphone users to interact directly with their own photos of media items to receive audio feedback or narration on demand.

Mobile phones are frequently used to determine one's location and navigation directions, and they can also provide a platform for connecting tourists with each other. This paper proposes a system that uses a set of geotagged photos to automatically compute the geographic location of another photo and then augment that photo with text and images that enable collaboration and enhance navigation. ...

Traditionally, stories are considered to be made of a fabula and a discourse. The fabula is the chronological sequence of events happening in the story world. The discourse is the re-ordered sequence of tellings of those events. Most previous work on storytelling has focused on a fabula-driven pipeline, where the fabula is generated independently of and prior to the discourse. However, to creat...
