Patent number: 11936945Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed that improve short content identification in an audio stream through channel change detection and audio block realignment. Example instructions cause one or more processors to form a first audio block from an audio stream, detect whether the first audio block contains a channel change, the first audio block being one of a plurality of audio blocks the accessed audio, determine an offset of time from a beginning of the first audio block to when the channel change occurs in response to the channel change being detected in the first audio block, and create a new audio block aligned to start at the offset of time beyond the beginning of the first audio block using audio information from the audio stream, the new audio block to include a single channel of audio stream data.Type: GrantFiled: July 27, 2022Date of Patent: March 19, 2024Assignee: The Nielsen Company (US), LLCInventor: Kevin Keqiang Deng

Publication number: 20230196726Abstract: Methods and systems for automated construction of an anonymized facial recognition library are disclosed. A camera of a client device may capture a first plurality of images of faces of members of a panel of viewers of media content presented on a content presentation device collocated with the client device during viewing sessions. A first machine learning (ML) model may be applied to the first plurality to generate a second plurality of feature vectors, each associated with a different one of the images. One or more clusters of feature vectors of the second plurality may be computationally determined within a vector space of the feature vectors. A respective centroid feature vector may be determined for each respective cluster, and assigned a unique ID. A respective association between each cluster ID and a respective name ID may be determined based on panel-member information received at the client device.Type: ApplicationFiled: December 22, 2021Publication date: June 22, 2023Inventor: Kevin Keqiang Deng
