In this approach, the discrete cosine transform (DCT) is applied to each subband of the perceptual spectrogram, and the lower-ordered DCT coefficients representing the subband envelopes are retained to generate multiple hash values. The corresponding database matching algorithm is also extended which allows for an efficient search in the database given a short query audio clip. The algorithm is implemented and compared with the Philips Robust Hash (PRH) algorithm proposed in [1], and experimental results show that the SEH algorithm achieves a significant improvement over the baseline system under various distortions.Asia-Pacific Signal and Information Processing Association, 2009 Annual Summit and Conference, International Organizing CommitteeConference Paperapplication/pdfhttp://hdl.handle.net/2115/39812https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/39812/1/WA-P1-5.pdfProceedings : APSIPA ASC 2009 : Asia-Pacific Signal and Information Processing Association, 2009 Annual Summit and Conference8138162009-10-04engpublisher
