Method and apparatus for calculating a similarity distance between the second feature vector and the first feature vector

摘要

The method of calculating a similarity metric between a first feature vector of a first audio and/or video signal and a second feature vector of a second audio and/or video signal of the invention comprises the step of calculating a distance between the first feature vector and the second feature vector, both the first feature vector and the second feature vector comprising a feature value of a second dimension, wherein a weighting factor is used that gives a stronger weight to the first dimension than to the second dimension. The electronic device of the invention comprises electronic circuitry, which is operative to perform the method of the invention. The software of the invention makes a programmable device operative to perform the method of the invention.
