New pending patent applications are published by the USPTO on Thursdays. This week's Spotlight Applications concern aspects of digital watermarking and digital fingerprinting. Assigned to Thompson (FR), the first application discloses techniques for watermarking a three dimensional object and method for obtaining a payload from a three dimensional object. Assigned to Dolby, the second application discloses techniques for acquisition, recovery, and matching of unique information from file-based media for automated file detection.
20160063661, "Method for watermarking a three dimensional object and method for obtaining a payload from a three dimensional object," assigned to Thompson Licensing (FR).
A method for watermarking a three-dimensional object is disclosed. The watermarking method comprises computing shape descriptor of a local neighborhood of a current vertex among the plurality of vertices of the three-dimensional object; obtaining a target shape descriptor from the shape descriptor using a quantization grid associated with a watermark payload; and modifying said local neighborhood wherein a position of at least one vertex of said local neighborhood is modified such that a shape descriptor of said modified local neighborhood is close to said target shape descriptor and wherein said current vertex is not modified. A method for obtaining payload from a three-dimensional object, a 3D object carrying a watermark and devices implementing the disclosed methods are further disclosed.
20160066032, "Acquisition, recovery, and matching of unique information from file-based media for automated file detection," assigned to Dolby Labs.
A media fingerprint archive system generates and archives media fingerprints from second media content portions such as commercials. A downstream media measurement system can extract/derive query fingerprints from an incoming signal, and query the media fingerprint archive system whether any of the query fingerprints matches any archived fingerprints. If so, the media measurement system can perform media measurements on a specific secondary media content portion from which the matched query fingerprint is derived. If not, the media measurement system can analyze media characteristics of a media content portion to determine whether the media content portion is a secondary media content portion and perform media measurement if needed to. The media measurement system may send fingerprints from an identified secondary media content portion to the media fingerprint archive system for storage.
