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...

More than forty-five years after the assassination of U.S. President Kennedy theories continue to circulate suggesting that the accused assassin, Lee Harvey Oswald, acted as part of a larger conspiracy. It has been argued, for example, that incriminating photographs of Oswald were manipulated, and hence evidence of a broader plot. We describe a detailed 3-D analysis of the Oswald photos to dete...

Many photo-taking scenarios have emotional triggers such as happiness, joy, or in general a good feeling. In this paper we postulate that if a photo was taken to preserve a good feeling, it will most likely trigger a good feeling when re-visiting the photo later on. We present an approach to classify photos and decide automatically whether they have been taken to preserve a good feeling or not....

We study platform owner’s decision to enter the market complementary to its platform with its own rival complement, and the consequences of such an entry on complementors’ innovation behavior. We ask: if a platform owner like Google releases an app for its Android platform, does it keep app developers from innovating in the future? We investigate two mechanisms that suggest entry to stimulate c...

In this paper we report a new empirical study of the photographic portrayal of family members at home. Adopting a social psychological approach and focusing on intergenerational power dynamics at home, our research explores the use of domestic photo displays in family representation. Mother-teen pairs from eight families in the south of England were interviewed at home about their interpretatio...

ecause digital cameras are so easy to use, consumers tend to take and accumulate more and more digital photos. Hence they need effective and efficient tools to organize and access photos in a semantically meaningful way without too much manual annotation effort. We define semantically meaningful as the ability to index and search photos based on the purposes and contexts of taking the photos. F...
