Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for distributed nearest-neighbor search for image retrieval are disclosed. An example distributed image retrieval system includes a root server and a plurality of leaf servers. The root server controls the clustering of images in the image corpus, and determines the assignment of image clusters to a collection of leaf servers. Each leaf server is independently configured to perform a two-stage nearest-neighbor search in a locality-sensitive hash space for a received query image within the leaf server's assigned images clusters. Thus, the distributed image retrieval system is modular and amendable to tuning, modifications, duplication, and replacement on a per-server basis. In addition, the design of the image retrieval system allows flexible load balancing among the leaf servers.

Claim (Index 10):
The method of  claim 7 , wherein assigning each of the image clusters to one or more respective image search servers comprises:\n determining a respective estimated search volume for each of the image clusters; and assigning each of the image clusters to the one or more respective image search servers according to the respective estimated search volume of the image cluster, wherein at least one image search server is assigned to more than one image cluster or at least one image cluster is duplicated on more than one image search server.
