Abstract:
A signal processing method for detecting and analyzing a pattern reflecting the semantics of the content of a signal, the method comprising the steps of:extracting, from a segment consisting of a sequence of consecutive frames forming together the signal, at least two features which characterize the properties of the segment; calculating, using at least one extracted feature, a criterion for measurement of a similarity between a pair of segments for every extracted feature and measuring a similarity between a pair of segments according to the similarity measurement criterion; and detecting, using at least two of the features and the similarity determination criterion, a similarity chain consisting of two or more, similar to each other, of the segments; whereby detecting a similarity chain includes calculating multiple similarity values for the pair of segments according to respective extracted features and calculating the value of a weighted combination of said similarity values.
