New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital fingerprinting. Assigned to Gracenote the first patent addresses techniques for media channel identification with video multi-match detection and disambiguation based on audio fingerprint. Assigned to Tencent (CN), the second patent addresses techniques for image information recognition processing.
10,440,430, "Media channel identification with video multi-match detection and disambiguation based on audio fingerprint," assigned to Gracenote.
Disclosed are methods and systems to help disambiguate channel identification in a scenario where a video fingerprint of media content matches multiple reference video fingerprints corresponding respectively with multiple different channels. Given such a multi-match situation, an entity could disambiguate based on an audio component of the media content, such as by further determining that an audio fingerprint of the media content at issue matches an audio fingerprint of just one of the multiple channels, thereby establishing that that is the channel on which the media content being rendered by the media presentation device is arriving.
10,438,086, "Image information recognition processing method and device, and computer storage medium," assigned to Tencent Technology (Shenzhen) Company Limited (CN)
An image information recognition processing method, device and a computer storage medium are provided. A first reference image and an image to be detected are acquired. Nth interception or cutting processing on the image to be detected is performed in a specified direction to obtain an Nth sub-image according to a first preset rule. First attribute values and/or second attribute values of the first reference image and the Nth sub-image are acquired respectively, the first attribute values being configured to represent color distribution information of the images and the second attribute values being configured to represent fingerprint information of the images. When the first attribute value and/or second attribute value of the Nth sub-image and the corresponding attribute value(s) of the first reference image meet a predetermined condition, it is recognized that the image to be detected to which the Nth sub-image belongs is matched with the first reference image.
