Abstract

The invention provides characteristic parameter extraction of pulse wave, belonging to the technical field of Chinese medical pulse condition quantization. A method for extracting characteristic parameters of pulse wave comprises the following steps of: determining all main peak points in a pulse wave signal; determining a starting point of each corresponding pulse wave signal period according to each main peak point; determining all possible extreme points in the pulse wave signal period; removing interference extreme points in the possible extreme points to accurately obtain characteristic points in a pulse wave signal period signal; and acquiring the characteristic parameters based on the information on characteristic points. The method is accurate in characteristic point positioning; and the extracted characteristic parameters are accurate, scientific and reliable.

Description

technical field [0001] The invention belongs to the technical field of pulse condition quantification in traditional Chinese medicine, and relates to the extraction of characteristic parameters of pulse condition by using computer technology. In the extraction process, extreme points are used to accurately locate the characteristic points in the pulse wave signal. Background technique [0002] Pulse diagnosis is a diagnostic method for observing and judging disease conditions based on "pulse condition". The reason why pulse diagnosis is important is that the pulse condition can convey the physiological and pathological information of each part of the body, and it is a window to peep into the functional changes in the body, which can provide an important basis for the diagnosis of diseases and syndromes. [0003] Traditional Chinese medicine pulse diagnosis is completely dependent on the experience of the doctor. The doctor obtains the patient's pulse information to realize t...
