Microsoft Research’s SkyFinder, uses an algorithm that analyzes images of the sky and automatically extracts key attributes “cloudy sky, blue sky, sunset, horizon, etc.” to help people search for specific types of photos. SkyFinder is a research project, not a Microsoft product, so the online interface isn't publicly available, revealed. In the meantime, Microsoft has released following video and a paper explaining the technology. The research was conducted using hundreds of thousands of images of the sky, downloaded from Flickr and user groups. "In an offline indexing process, a set of semantic sky attributes (e.g., category, layout, richness, horizon, sun position) are automatically extracted from each image," the researchers explain in the paper. "Then in an online search, the user can interactively search sky images based on any combination of preferred sky attributes."
