Tracking position of at least one object in video frames. The tracking includes processing an initial frame of a set of frames, the processing the initial frame using feature extraction to identify locations of features of the at least one object. The tracking further includes using motion estimation to track locations of the features in subsequent frames of the set of frames, including iteratively performing: obtaining a next frame of the set of frames, and applying a motion estimation algorithm as between the next frame and a prior frame of the set of frames to identify updated locations of the features in the next frame, where locations of the features as identified based on the prior frame are used as input to the motion estimation algorithm to identify the updated locations of the features in the next frame based on searching less than an entirety of the next frame.

Object position tracking using motion estimation

A method includes tracking positions of object(s) in video frames, including: processing an initial frame of a set of frames of the video frames using feature extraction to identify locations of features of the object(s), obtaining a next frame of the set and applying a motion estimation algorithm as between the next frame and a prior frame to identify updated locations of the features in the next frame, where locations of the features as identified based on the prior frame are used as input to the motion estimation algorithm to identify the updated locations of the features in the next frame based one searching less than an entirety of the next frame. The tracking further includes recognizing occurrence of an event, halting the iteratively performing, and repeating, for at least one subsequent set of frames, the processing an initial frame and the using motion estimation.

A processor receives a media rating associated with a first media program and metadata associated with the first media program. The processor stores the metadata and the media rating associated with the first media program in a local database. The processor receives a second media program absent a media rating. The processor determines metadata associated with the second media program absent the media rating. The processor searches the local database based on the metadata associated with the second media program absent the parental control rating. The processor matches the metadata associated with the second media program absent the media rating to the metadata of the first media program including the media rating, and the processor applies the media rating of the first media program to the second media program.
