Abstract

The invention provides a pulse feature extraction system based on EEMD-PNCC. The pulse feature extraction system comprises a pulse acquisition module, a pulse curve model construction module and a pulse feature processing module. The pulse acquisition module is used for acquiring pulse data information and preprocessing the pulse data information, the pulse curve model construction module is used for receiving the preprocessed pulse data information and constructing a multi-cycle time domain feature model according to the preprocessed pulse data information, the pulse feature processing module is used for obtaining pulse frequency domain feature information according to the preprocessed pulse data information and obtaining a pulse feature model according to a multi-cycle time domain feature model and the pulse frequency domain feature information. Complete pulse feature information can be accurately obtained, subsequent quantitative analysis on the pulse feature information is facilitated, and doctors can be assisted in performing clinical objective diagnosis through the pulse feature information. Correspondingly, the invention further provides a pulse feature extraction method based on the EEMD-PNCC.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a pulse feature extraction system and method based on EEMD-PNCC. Background technique [0002] Pulse pressure and changes in pulse characteristics are important bases for evaluating the physiological and pathological state of the human cardiovascular system. Whether it is TCM pulse monitoring or Western medical cardiovascular disease examination, all attempts are made to extract various physiological and pathological information from pulse wave characteristics. At present, pulse diagnosis mainly relies on the subjective diagnosis of doctors, but due to the complexity and variety of pulse signals, doctors may have the problem of subjective misdiagnosis in clinical diagnosis. In order to solve the problem of subjective misdiagnosis of doctors in clinical diagnosis, it is necessary to use pulse characteristics for quantitative analysis, and the key to objective diagn...
