“Spotting a face in a crowd, or recognizing any small or distant object within a large image, is a major challenge for computer vision systems. The trick to finding tiny objects, say researchers at Carnegie Mellon University, is to look for larger things associated with them. An improved method for coding that crucial context from an image has enabled Deva Ramanan, associate professor of robotics, and Peiyun Hu, a Ph.D. student in robotics, to demonstrate a significant advance in detecting tiny faces. When applied to benchmarked datasets of faces, their method reduced error by a factor of two, and 81 percent of the faces found using their methods proved to be actual faces, compared with 29 to 64 percent for prior methods.”
