Similarity information determining device, similarity information determination method, autocorrelation information determining device, cross-correlation information determining device and computer program

摘要

An apparatus for determining similarity information based on one or more input signals describes the number of zero crossings in each portion for at least one portion of the one or more input signals. Configured to determine the zero crossing information to perform. The apparatus is configured to perform a comparison based on the zero-cross information to determine similarity information. A method and computer program for determining similarity information is also described. Furthermore, the apparatus for determining autocorrelation information and the apparatus for determining cross-correlation information are based on similar considerations. [Selection] Figure 1
