Abstract:
An apparatus for determining a similarity information on the basis of one or more input signals is configured to determine a zero crossing information describing a number of zero crossings in a respective portion for a plurality of portions of at least one of the one or more input signals. The apparatus is configured to perform a comparison on the basis of the zero crossing information, in order to determine the similarity information. A method for determining a similarity information and a computer program are also described. Moreover, an apparatus for determining an autocorrelation information and an apparatus for determining a cross-correlation information are based on similar considerations.

Claim (Index 18):
A method for determining a similarity information on the basis of one or more input signals which are audio signals or video signals,\n wherein the method comprises determining a zero crossing information describing a number of zero crossings in a respective portion for a plurality of portions of the at least one of the one or more input signals, and wherein the method comprises performing a comparison on the basis of the zero crossing information, in order to determine the similarity information describing a similarity between different parts or sections of a single input signal or between different parts or sections of two signals to be compared; wherein the method comprises determining two or more representative values per signal block for a plurality of signal blocks, wherein the two or more representative values describe features of the signal blocks, and wherein the two or more representative values comprise a zero crossing value which is a zero crossing information; and wherein the method comprises determining spectral flatness measures as one of the two or more representative values which are determined per signal block, and/or wherein the method comprises determining spectral flux values as one of the two or more representative values which are determined per signal block, wherein the spectral flux values describe, in the form of a single quantitative value, a change between spectra of two respective successive signal blocks; wherein the method comprises performing the comparison on the basis of the two or more representative values, in order to determine the similarity information, wherein a first comparison is performed on the basis of a sequence of representative values of a first type for a plurality of signal blocks, and wherein a second comparison is performed on the basis of a sequence of representative values of a second type for the plurality of signal blocks, wherein a first zero crossing value sequence, which comprises a plurality of zero crossing values, and a second zero crossing value sequence, which comprises a plurality of zero crossing values, are compared, to acquire a similarity information describing a similarity between a first signal section and a second signal section, wherein the first zero crossing value sequence corresponds to the first signal section, and wherein the second zero crossing value sequence corresponds to the second signal section, and wherein the zero crossing values constitute the zero crossing information, wherein a result of the first comparison and a result of the second comparison is compared, in order to acquire a reliability information; wherein the method comprises receiving one or more audio signals or one or more video signals as the one or more input signals, and determining the zero crossing information on the basis of the one or more audio signals or on the basis of the one or more video signals.
