"But what you may not know is that you also have helped archivists decipher distorted characters in old books and newspapers so that they can be posted on the Web."

Computer Model Mimicks How Brain Recognizes Street Scenes

ScienceDaily — "At last, neuroscience is having an impact on computer science and artificial intelligence (AI). For the first time, scientists in Tomaso Poggio's laboratory at the McGovern Institute for Brain Research at MIT applied a computational model of how the brain processes visual information to a complex, real world task: recognizing the objects in a busy street scene. The researchers were pleasantly surprised at the power of this new approach."
