Abstract: A location estimation system includes a plurality of Kalman filters, a UWB position system, a pressure sensor, a temperature sensor and a MEMs chip that provides gyroscope, accelerometer and magnetometer information. The data is Kalman filtered to determine precise location information that is more precise any sensor that is processed to determine the probable location of a device. The system further includes at least one camera based location determination systems is configured to provide either two dimensional or three-dimensional data wherein the system utilizes the absolute location information as well as the camera data to determine a precise location notwithstanding anomalies in the absolute location information. In one embodiment, the data from the location estimation system is fused with data from the camera based location determination system to generate data that, overall, is more accurate than data from either source.

Abstract: A sheet music search and discovery system is disclosed that uses specific mathematical rules to analyze and characterize sheet music and provides functionality for users to identify sheet music based on those characterizations. The system stores sheet music data and metadata characterizing each composition, provides a graphical user interface that provides functionality for users to search the sheet music data for compositions, and generates search results based at least in part on the metadata characterizing each composition. In one embodiment, metadata describing structured sheet music data is generated using a global vector space that includes semantic representations of elements extracted from a large corpus. In another embodiment, metadata describing unstructured sheet music data is generated using machine learning-based pattern recognition.

Abstract: A distributed video encoding system splits an input video into video segments. The video segments are encoded using multiple video encoding nodes. Prior to the process of splitting the sequence into video segments, the video is analyzed to generate a dependency map. Intelligent segmentation is performed using the dependency map so that each video segment includes all the video frames from which other video frames within that segment have been encoded in the input video. For example, picture headers are inspected to determine the temporal distance of the farthest past and future reference frames used for encoding frames of a video.

Abstract: An online system more efficiently streams multimedia content over the Internet for play back on client devices with varying computing power and network bandwidths by generating enhanced manifest files that more efficiently identify suitable media representations of the multimedia content. Each media representation has multiple media segments according to predefined byte ranges and a manifest file, which identifies location of the media file, bitrates, resolution, byte range, total duration, and other metadata. The online system customizes a manifest file for a user based on various factors including device capacity, network connectivity type and geolocation of the user. The online system also generates manifest fetch commands, which more efficiently fetch media segments for streaming. In response to changes of streaming server and media file (e.g., increased popularity), the online system dynamically updates corresponding manifest files.
