Abstract:
Coding quantized transform coefficients as occur in image compression combines a position coding method to code the position of clusters of consecutive non-zero-valued coefficients with an amplitude coding method to code the amplitudes of a concatenation of a plurality of the clusters. The amplitude coding method exploits that runs of amplitude 1 coefficients are more likely in the clusters than runs of other coefficient amplitudes.
Abstract:
In one embodiment, a method includes recording a sequence of online activities of a first user. The online activities include online consumption of online content by the first user. The method includes constructing a path based on the sequence of online activities of the first user. The path includes a sequence of online activity points that each correspond to one of the online activities in the sequence of online activities of the first user, and the path enables a second user to experience personally for themselves at least an approximation of the sequence of online activities of the first user. The method includes communicating the path for traversal of a portion of the path by the second user.
Abstract:
In one embodiment, a method includes accessing first data describing online activities of a user and accessing second data describing online activities of each of one or more content publishers. The method includes, based at least in part on the first data and the second data, determining one or more similarities between the user and each of the content publishers. The method includes, based at least in part on one or more of the similarities, selecting each of one or more of the content publishers as a key influencer for the user and selecting particular content published by a particular one of the key influencers for summary and delivery to the user. The method includes generating a summary of the particular content and automatically delivering to the user the particular content and the summary.
