摘要： A method and apparatus for coding and decoding the fingerprint of a multimedia item such as video or audio is disclosed. A multimedia content temporal, such as a video segment or audio segment, is described by a coarse fingerprint and a plurality of fine fingerprints, each fine fingerprint corresponding to a temporal sub-interval of said temporal interval, said temporal sub-interval typically being smaller than said temporal interval. One or more fine fingerprints are encoded in a non-predictive way, with no reference to the temporally neighboring signatures, and one or more fine fingerprints are encoded in a predictive way, from the temporally neighboring signatures. The predictive encoding entails computing the difference between neighboring fine fingerprints to make up a prediction difference matrix, scanning said prediction difference matrix into a one dimensional vector by vectorising along rows or along columns or along diagonals or along any suitable scanning pattern, and performing lossless encoding on the one dimensional vector by an appropriate method, preferably selected, at least in part, based on the scanning method used.

摘要： A method and apparatus for processing a first sequence of images and a second sequence of images to compare the first and second sequences is disclosed. Each image of the first sequence and each image of the second sequence is processed by: (i) processing the image data for each of a plurality of pixel neighbourhoods in the image to generate at least one respective descriptor element for each of the pixel neighbourhoods; and (ii) forming an overall image descriptor from the descriptor elements. Each image in the first sequence is compared with each image in the second sequence by calculating a distance between the respective overall image descriptors of the images being compared. The distances are arranged in a matrix, and the matrix is processed to identify similar images.

摘要： A method and apparatus for processing a first sequence of images and a second sequence of images to compare the first and second sequences is disclosed. Each of a plurality of the images in the first sequence and each of a plurality of the images in the second sequence is processed by (i) processing the image data for each of a plurality of pixel neighborhoods in the image to generate at least one respective descriptor element for each of the pixel neighborhoods, each descriptor element comprising one or more bits; and (ii) forming a plurality of words from the descriptor elements of the image such that each word comprises a unique combination of descriptor element bits. The words for the second sequence are generated from the same respective combinations of descriptor element bits as the words for the first sequence. Processing is performed to compare the first and second sequences by comparing the words generated for the plurality of images in the first sequences with the words generated for the plurality of images in the second sequence.
