Behold: An alternative to Flickr and Google Image Search

BeholdTM is a search engine for high-quality Flickr images. It aims to answer your queries based on what is inside the images -- at the pixel level. It offers a completely new way to search for images, using techniques of computer vision. It is different to standard image search engines, such as Flickr or Google, because those search through images using only image tags and filenames.

Behold looks for high quality images, so you don't have to sift through hundreds of poorly taken pictures to find a good one. Behold uses both aesthetic and technical quality indicators to find some of the best images available online.

Behold draws computational power from Amazon Elastic Compute Cloud (EC2) to handle large volumes of images.  Access it here.
