Abstract
A method of identifying an item of video content involves providing a spatial hash value and a temporal hash value for each image in a video collection. Each hash value is based on a measure of the entropy in differences between pixel values. A table of the pair of hash values against timecode is created and ordered according to one of the hash values. A search for a given pair of hash values can then be confined to that part of the table that matches the first value.
