摘要:
A media fingerprint is derived from a portion of media content. Information is associated with the media content portion based on the derived media fingerprint. Upon linking to the associated information, the associated content is presented with the media content portion. The media fingerprint includes a unique representation of the media content portion that is derived from a characteristic component of the media content portion. The media content may comprise an original instance of content or a derivative instance of the original content.

At least one object within a portion of media content is recognized. The object is essentially a feature of the media content portion. Information is associated with the recognized object based on recognizing the object.

Deriving a fingerprint of an image corresponding to media content involves selecting at least two different regions of the same image, determining a relationship between the two regions, and deriving a fingerprint of the image based on the relationship between the two regions of the image.

Techniques are provided for dynamic configuration of search parameters for multimedia fingerprint databases that use weak bits. A multimedia fingerprint database, which stores reference fingerprints and uses weak bits, is maintained. Maintaining the database includes dynamically configuring one or more of the following parameters: a fingerprint length of those portions of the reference fingerprints that are used to identify multimedia objects; an index length of the index used to index those portions of the reference fingerprints that are used to identify multimedia objects; a threshold that is used to determine whether multimedia objects are correctly identified; and a number of the weak bits in the reference fingerprints.
摘要:
Attributes are identified in media content. A classification value of the media content is computed based on the identified attributes. Thereafter, a fingerprint derived from the media content is stored or searched for based on the classification value of the media content.
摘要:
Multiple candidate feature components of media content or projection matrices (or other hash functions, e.g., non-linear projections) are identified. Each of the candidate projection matrices (or other hash functions) includes an array of coefficients that relate to the candidate features. A subgroup of the candidate features or the projection matrices (or other hash functions) are selected based at least partially on an optimized combination of at least two characteristics of the candidate features or projection matrices (or other hash functions). Media fingerprints that uniquely identify the media content are derived from the selected optimized subgroup. Optimal projection matrices (or other hash functions) may be designed. Performance or sensitivity (e.g., search time) characteristics of the fingerprints are thus balanced with robustness characteristics thereof.
摘要:
A portion of media content is accessed. Components from a first and each subsequent spatial regions of the media content are sampled. Each spatial region has an unsegmented area. Each subsequent spatial region includes those within its area as elements thereof or the spatial regions may partially overlap. The regions may overlap independent of a hierarchical relationship between the regions. A media fingerprint is derived from the components of each of the spatial regions, which reliably corresponds to the media content portion, e.g., over geometric attacks such as rotation.

Methods, apparatuses and program logic in storage media to process media data for quality enhancement. Information is accepted from a resource constrained device, e.g., a wireless portable device related to the quality enhancement and/or environmental quantities such as background noise and/or ambient lighting for the device. Media data is data processed to achieve quality enhancement using at least some of the accepted information to generate processed output. The data processing of the media data includes processing when or where one or more resources sufficient for the processing are available.
