Abstract

The invention discloses an electrocardio signal identification method and system based on multi-feature sparse representation. The method comprises the following steps: acquiring an electrocardio signal to be identified; performing noise cancellation processing on the electrocardio signal to be identified; performing cadence processing on the noise cancelled electrocardio signal to be identified to obtain a plurality of single-period electrocardio signals; performing multi-feature extraction on each single-period electrocardio signal; inputting all features obtained in extraction into an alternating direction method of multipliers, performing coefficient solving with multi-feature sparse representation to finally obtain an optimized coefficient matrix; and inputting the optimized coefficient matrix into a pre-trained classifier, and outputting an identification result.

Description

technical field [0001] The present disclosure relates to the technical field of ECG signal recognition, in particular to a method and system for ECG signal identification based on multi-feature sparse representation. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] Recently, as a new biometric identification technology, ECG has become a research hotspot due to its liveliness and difficulty of being imitated. There are many existing ECG signal identification methods, such as methods based on principal component analysis, linear discriminant analysis, fiducial point analysis, no fiducial point analysis, and deep neural network. [0004] In the process of realizing the present disclosure, the inventors found that the following technical problems existed in the prior art: [0005] At present, the existing ECG signal identification method only utiliz...
