Abstract: Systems and methods for a dynamic visual search engine are provided. In one example method, a criteria used to partition a set of compressed image descriptors into multiple database shards may be determined. Additionally, a size of a dynamic index may be determined. The dynamic index may represent a dynamic number of images and may be configured to accept insertion of reference images into the dynamic index that can be search against immediately. According to the method, an instruction to merge the uncompressed image descriptors of the dynamic index into the database shards of the compressed image descriptors may be received, and the uncompressed image descriptors of the dynamic index may be responsively merged into the database shards of the compressed image descriptors based on the criteria.

Abstract: A method and apparatus for surfacing content during a photo sharing process is described. The method may include detecting the initiation of a social networking photo sharing process for a digital image. The method may also include transmitting digital image data corresponding to the digital image to a content surfacing server to locate content relevant to the digital image. The method may also include receiving one or more items of data relevant to the digital image from the content surfacing server. Furthermore, the method may include presenting a notification, before the digital image is uploaded to a social networking system by the social networking photo sharing process, to a user to indicate that content relevant to the digital image has been received.
