Matching modern to historical images requires a special effort in the sense of dealing with historical photos. While there are many robust matching techniques which are vectoror binary-based that perform effectively on modern images, they are not accurate on historic photos. Photos of different landmarks were gathered for a long timeline taken in different conditions of illuminations, position,...

Music players for personal computers are often featured with music visualization by generating animated patterns according to the music’s low-level features such as loudness and spectrum. This paper proposes an emotion-based music player which synchronizes visualization (photos) with music based on the emotions evoked by auditory stimulus of music and visual content of visualization. For emotio...

Since the arrival of digital cameras, many people are faced to the challenge of organizing and retrieving the overwhelming flow of photos their life produces. Most people put no metadata on their photos, and we believe this is because existing tools make a very limited use of them. We present a tool, Camelis, that offers users with an organization of photos that is dynamically computed from the...

Many privacy issues concerning photos on the Web and particularly the social Web have been discussed in the past. However, much of this discussion is based on anecdotal evidence and has focused on media uploaded by users themselves. We present the results of a survey conducted with 414 participants that studies user awareness of privacy issues concerning the sharing of media including media sha...

This paper describes and implements an attempt to solve the problem of determining depth from defocus when given a focal stack (set of photos taken at different focuses) created from photos captured with a hand-held camera with unknown calibration. Although the photos may initially suffer from significant parallax due to camera/hand movement during capture, the image alignment steps explained i...

Previous research has demonstrated that hormones, relationship goals, and social context influence interest in the opposite sex. It has not been previously reported, however, whether having a current sexual partner also influences interest in members of the opposite sex. To test this, we obtained explicit and implicit measures of interest by measuring men's and women's subjective ratings and re...

Recovering 3D objects from 2D photos is an important application in the areas of computer vision, computer intelligence, feature recognition, and virtual reality. This paper describes an innovative and systematic method to integrate automatic feature extraction, automatic feature matching, manual revision, feature recovery, and model reconstruction as an effective recovery tool. This method has...

The popularity of photo-sharing websites like Flickr give us a chance to observe what ordinary users do in their daily life. Particularly, Flickr allows the users to provide personalized tags when uploading photos, and then we can annotate Flickr photos using user-supplied tags. This paper proposes an approach to automatically annotate Flickr photos by exploiting user-supplied tags. Usersupplie...

In psychology, theory-driven researches are usually conducted with extensive laboratory experiments, yet rarely tested or disproved with big data. In this paper, we make use of 418K travel photos with traveler ratings to test the influential “broaden-and-build” theory, that suggests positive emotions broaden one’s visual attention. The core hypothesis examined in this study is that positive emo...
