Inspired by the recent Democratic National Primary, we consider settings in which the members of a distributed population must balance their individual preferences over candidates with a requirement to quickly achieve collective unity. We formalize such settings as the “Democratic Primary Problem” (DPP) over an undirected graph, whose local structure models the social influences acting on

This paper discusses evaluation in the context of public art and specifically of interactive digital art. The study reported is of ‘Light Logic’, an exhibition of retrospective and current drawings, paintings and interactive digital works by the second author. The study was conducted by Site Gallery Sheffield in association with UK and Australian researchers. A survey of evaluation practice amo...

We examine the ‘native’ metadata and organizational structures that individuals create for their personal photo digital libraries, by analyzing the behavior of photo collectors as recorded in 37 autoethnographies and ethnographies. The findings confirm several common assumptions about how people organize their photos that have been the basis for features in earlier photo digital libraries—that ...

Making a note for each digital photo one by one is not efficient when the photo collection is thousands of units. Therefore, users will want an efficient approach to retrieve photos based on metadata of their digital photos. So, annotation process would play a vital role in the retrieval process. In this paper, we describe our growing work on a group of photo annotations for personal digital ph...

The problems of photo aesthetic and photo quality are similar, but not exactly the same. In photo aesthetic assessment, we seek photos that looks beautiful to people. The aesthetic score of a photo can be affected by the photo’s color tone, composition, layout, and etc. In photo quality assessment, we seek photos that are in high quality. The quality score of a photo can be affected by shake, b...

With the rapid growth of personal digital content created by a wide array of digital devices, photo sharing across the network has become a routine demand. Existing approaches to photo sharing require much user manipulation, and the process tends to be tedious and timeconsuming. This research proposes “Photo Agent,” a multi-agent system that facilitates sharing of digital photos based on a user...

Current advances in digital technology promote capturing and storing more digital photos than ever. While photo collections are growing in size, the amount of time that can be devoted to viewing, managing, and sharing digital photos remains constant. Photo decision-making and selection has been identified as key to addressing this concern. After conducting exploratory research on photo decision...

This paper presents u-Photo which is an interactive digital still image including information of pervasive services associated with networked appliances and sensors in pervasive computing environment. U-Photo Tools can generate a u-Photo and provide methods for discovering contextual information about these pervasive services. Users can easily find out this information through the metaphor of ‘...

object: the gold standard for evaluating bone mineral density is dual energy x-ray absorptiometry (dexa).  prior studies have shown poor reliability using analog wrist x-rays in diagnosing osteoporosis. our goal was to investigate if there was improved diagnostic value to visual assessment of digital hand x-rays in osteoporosis screening. we hypothesized that similar to analog counterparts, dig...

Online photo libraries face the problem of organizing their rapidly growing image collections. Fast and reliable image retrieval requires good qualitative captions added to a photo; however, this is considered by photographers as a time-consuming and annoying task. In order to do it in a fully automated way, the process of augmenting a photo with captions or labels starts by identifying the obj...
