Following a series of experiments in which six orangutans and one gorilla discriminated photographs of different animal species in a two-choice touch screen procedure, Vonk & MacDonald (2002) and Vonk & MacDonald (2004) concluded that orangutans, but not the gorilla, seemed to learn intermediate level category discriminations, such as primates versus non-primates, more rapidly than they learned...

Users can explore the world by viewing place related photos on Google Maps. One possible way is to take the nearby photos for viewing. However, for a given geo-location, many photos with view directions not pointing to the desired regions are returned by that world map. To address this problem, prior know the poses in terms of position and view direction of photos is a feasible solution. We can...

Image organizers such as imgSeek and GIFT allow query by image content (QBIC). QBIC help users find duplicate and similar photos. However, the similarity is measured based on color, texture and shape, not in terms of people. We implemented a “query by face” feature for organizing personal digital photos, using face detection and recognition techniques. We used the OpenCV library to extract face...

Sharing photos through mobile devices has a great potential for creating shared experiences of social events between co-located as well as remote participants. In order to design novel event sharing tools, we need to develop indepth understanding of current practices surrounding these so called ‘event photos’photos about and taken during different social events such as weddings picnics, and mus...
