Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND STORAGE MEDIUM FOR STORING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/008625
Kind Code:
A1
Abstract:
The present invention provides a signal processing technique that allows information to be acquired about an object signal component that is modelled at low memory cost even with a large variance in object signals. A signal processing device 700 comprises: a feature extraction unit 101 that extracts, from a target signal, a feature amount representing the feature of the target signal; an analysis unit 103 that calculates a weight representing each intensity for a plurality of the object signals included in the target signal on the basis of a signal element basis that represents a plurality of types of the object signals by linear combination and the information about the linear combination; a processing unit 704 that produces the information about a target object signal that is at least one type of the object signal included in the target signal on the basis of the weight; and an output unit 106 that outputs the information about the target object signal.
