摘要： A system and method detects matches between portions of video content. A matching module receives an input video fingerprint representing an input video and a set of reference fingerprints representing reference videos in a reference database. The matching module compares the reference fingerprints and input fingerprints to generate a list of candidate segments from the reference video set. Each candidate segment comprises a time-localized portion of a reference video that potentially matches the input video. A classifier is applied to each of the candidate segments to classify the segment as a matching segment or a non-matching segment. A result is then outputted identifying a matching portion of a reference video from the reference video set based on the segments classified as matches.

摘要： A method comprises: accessing a plurality of videos; retrieving a video access log; differentiating a viewers from the video access log; extracting demographic information from one or more viewers associated with the viewer that accessed the video; determining whether the demographic information includes demographic attributes of interest; generating and storing a multi-attribute demographic distribution for the viewer; generating a feature vectors for each of the videos based on video content of frames; associating each feature vector with a visual object within a frame within each video; generating and storing a subset of representative feature vectors by performing dimensionality reduction; in response to storing the subset of feature vectors and the multi-attribute demographic distribution for each video, generating a predicted distribution; and determining, for the viewer having extracted demographic information that does not include the demographic attributes of interest, predicted demographic attribute values using the predicted distribution.

摘要： Methods and systems for automated annotation of persons in video content are disclosed. In one embodiment, a method of identifying faces in a video includes the stages of: generating face tracks from input video streams; selecting key face images for each face track; clustering the face tracks to generate face clusters; creating face models from the face clusters; and correlating face models with a face model database. In another embodiment, a system for identifying faces in a video includes a face model database having face entries with face models and corresponding names, and a video face identifier module. In yet another embodiment, the system for identifying faces in a video can also have a face model generator.
