What kind of games do people play with digital images? To probe this question, we examine image-based gaming activity as exercised in the Flickr photo sharing system. Noticeably, a surprising number of user-moderated games are being played within the structure of Flickr groups. We provide an assessment of this activity and a first categorization of the exact types of games played: Recurrent the...

Subway is a participatory multi-located activist art project. It builds on the mediation of a dance performance by breaking a video apart into its image frames; creating a photo app in Android to re-use these frames as guides for a frame-by-frame reenactment; and finally reassembling the collected images into a new video. Through the affordances of digital and mobile media, it allowed participa...

The paper presents a new automatic technique for speckle reduction in the context of digital holography. Speckle noise is a superposition of unwanted spots over objects of interest, due to the behavior of a coherence source of radiation with the object surface characteristics. In the proposed denoising method, bidimensional empirical mode decomposition is used to decompose the image signal, whi...

We assessed the effects of the elimination of livestock in riparian systems at Hart Mountain National Antelope Refuge in southeastern Oregon, 23 years after the removal of cattle grazing, using 64 photos taken before grazing was removed compared with later retake photos. Two methods were used for this assessment: (1) a qualitative visual method comparing seven cover types and processes and (2) ...
