A series signal specific method, a device, and a program

Japanese Patent JP5976029

B2

PROBLEM TO BE SOLVED: To enable an accumulation signal corresponding to an input signal to be selected from a plurality of accumulation signals at high speed.SOLUTION: The feature vector of each section in each of a plurality of accumulation signals is extracted as a feature series by a feature series extraction unit 32. The secondary feature of each section in each of the plurality of accumulation signals is derived by a secondary feature derivation unit 34. The feature vector of each section in an input signal is extracted as a feature series by the feature series extraction unit 32. The secondary feature of each section in the input signal is derived by the secondary feature derivation unit 34. The secondary feature that has high specificity in the input signal is selected by a high specificity feature selection unit 44. The selected secondary feature and the derived secondary feature of the accumulation signal are collated by a feature collation unit 46. In this way, the accumulation signal corresponding to the input signal is selected.
