Publication number: 20170024384Abstract: Still and moving images that are stored on a network are expressed as feature vectors, which are then indexed in inverted indices. Hashes of the feature vectors are also stored in a hash database, with each set of similar hashes being placed in bucket. A visual search query is received and expressed as feature vectors, which are then hashed. Matches for the hashed query are searched for in the hash database to quickly find buckets of closely matching images. The feature vectors represented by the matched buckets may optionally be looked through in the indices to find closer, or fewer matches. When multiple inverted indices are searched, they are done so simultaneously, after which the results are aggregated and ordered according to a similarity metric.Type: ApplicationFiled: September 2, 2014Publication date: January 26, 2017Inventor: Shashi KANT

Publication number: 20170006123Abstract: Embodiments of the present invention are directed to a method of providing non-native notifications and system thereof. These notifications are generated by non-native applications that can be executed on a target device, specifically within a guest environment on the target device, or can be executed on a physically disjoint source device that is communicatively coupled with the target device via a local pairing mechanism or a service in a cloud. The application player and the source device are able to capture these non-native notifications. The target device is able to receive and present these non-native notifications to a user. Notifications include alerts, reminders, updates and messages generated by non-native applications. The user does not need to access the non-native applications, or the application player or source device they are executing on to see the non-native notifications. Instead, the user views these non-native notifications at a central location on the target device.Type: ApplicationFiled: September 13, 2016Publication date: January 5, 2017Applicant: BlueStack Systems, Inc.Inventors: Shashi Kant Sharma, Sharad Agrawal, Suman Saraf, David P.
