A computer program that automatically analyzes mounds of satellite images and other data could help climate scientists keep track of complex, constantly changing environmental conditions, according to an international team of researchers. "All of the data and information that is continually collected by satellites and sensors can cause tons of problems for scientists, who simply don't have the time to analyze every pixel of every satellite image," said James Wang, professor of information...

A pair of Penn State researchers has developed a statistical approach, called Automatic Linguistic Indexing of Pictures in Real-Time (ALIPR), that one day could make it easier to search the Internet for photographs. The public can participate in improving ALIPR's accuracy by visiting a designated Web site (http://www.alipr.com), uploading photographs, and evaluating whether the keywords that ALIPR uses to describe the photographs are appropriate. ALIPR works by teaching computers to recognize...

An art historian can tell by looking at the riot of bold, colorful brushstrokes.
