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...

Social connectedness is crucial to someone’s well-being. A case study is conducted to test whether the social connectedness of elderly people living in a nursing home and their family and friends can be improved through a photo frame. A SIM-based photo frame is used to keep the elderly people informed about the comings and goings of their loved ones. Eight elderly people living in a nursing hom...

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...

Personal photo collections are large and growing rapidly. Today, it is difficult to search such a photo collection for people who occur in them since it is tedious to manually associate face tags in photos. The key idea is to learn face models for friends and family of the user using tagged photos in a social graph such as Facebook as training examples. These face models are then used to automa...

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...

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...
