Visual hash tags via trending recognition activities, systems and methods

摘要

A system and method of treating image data as a visual hash tag are presented. A device is able to subscribe to a content channel, possibly a channel that provide social media information, by the act of recognizing related objects without requiring a user to annotate content with unnatural hash tags.

主权项

1. A digital content subscription system comprising:
a digital data processing module executable on a processor according to software instruction stored in a memory and configured to:
obtain a digital representation of an object;identify a set of features in the digital representation;derive a set of descriptors corresponding to the set of features, each descriptor of the set of descriptors existing within a descriptor space; anddetermine a plurality of weights, the plurality of weights comprising a weight of each descriptor in the set of descriptors based on a determination of relevance of a feature in the set features, the feature corresponding to the each descriptor; a channel database configured to store channel identifiers indexed with respect to related descriptors within the descriptor space, each channel identifier representative of a digital content channel; and a subscription module executable on a processor according to software instruction stored in a memory, the subscription module coupled with the channel database and the digital processing module, and configured to:
obtain the set of descriptors and the plurality of weights from the digital data processing module; andgenerate a list of channel identifiers from the channel database that have related descriptors near the set of descriptors within the descriptor space, wherein the generating utilizes the plurality of weights to search for related descriptors corresponding to only a subset of descriptors in the set of descriptors, the subset of descriptors corresponding to features in the set of features that are more relevant than other features in the set of features.
