Image searching techniques

摘要

A search for an image includes receiving a set of features corresponding to image characteristics that then are compared to features indexed for multiple stored images. A search result is produced based on the comparison. The received set of features may correspond to posterized image characteristics that then are compared to features that have been indexed and that correspond to posterized image characteristics for multiple stored images. The received set of features may be compared to features that have been indexed for multiple stored images in an inverted index. The inverted index may include a relationship between features and images including those features. Additionally or alternatively, the received set of features may be compared to a list of features, where the list of features includes a relationship between features and images including those features.
