Researchers design a search system that recognizes the features of pictures of the sky.

Last week at SIGGRAPH, an international conference on computer graphics, a group presented an innovative system designed to analyze images of the sky. Most commercial image-search systems figure out what's in an image by analyzing the associated text, such as the words surrounding a picture on a Web page or the tags provided by humans. But ideally, the software would analyze the content of the image itself. Much research has been done in this area, but so far no single system has solved the problem. The new system, called SkyFinder, could offer important insight into how to make an intuitive, automatic, scalable search tool for all images.
