DETECTING KNOWN VIDEO ENTITIES

摘要

In general, in one aspect, the disclosure describes a method for detecting a known video entity within a video stream. The method includes receiving a video stream and continually creating statistical parameterized representations for windows of the video stream. The statistical parameterized representation windows are continually compared to windows of a plurality of fingerprints. Each of the plurality of fingerprints includes associated statistical parameterized representations of a known video entity. A known video entity in the video stream is detected when a particular fingerprint of the Morality of fingerprints has at least a threshold level of similarity with the video stream.The disclosure also describes a method of determining a channel associated with a video stream. A method for specifying regions of interest for video event detection is also described. Furthermore, a method for ending advertisement insertion in a video stream is described.
