New Tool Makes a Single Picture Worth a Thousand – and more – Images

New Tool Makes a Single Picture Worth a Thousand – and more – Images

A photo is worth a thousand words, but what if the image could also represent thousands of other images?   New software developed by UC Berkeley computer scientists seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can [...]
