Method and system for displaying pulse condition waveform in real time based on face video

Abstract

The invention discloses a method and a system for displaying a pulse condition waveform in real time based on a face video. The method comprises the following steps: (1) collecting the face video and a standard pulse condition; (2) carrying out detection and area tracking on the collected face video image; (3) carrying out color space conversion; (4) amplifying the Euler video; (5) separating RGB channels to generate initial pulse waves; (6) de-noising the initial pulse wave signal; (7) performing Hilbert-Huang conversion on the pulse wave to obtain a Hilbert spectrum; (8) constructing a conditional generative adversarial network; (9) training a conditional generative adversarial network; and (10) reconstructing a pulse condition waveform. The pulse condition waveform can be visually displayed only by collecting the face video, use is convenient and fast, and the applicability is wide.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and system for real-time display of pulse waveforms based on human face video. Background technique [0002] The arteries of the human body are all over the body, and the pulse wave is a kind of information window reflecting the physiological state or pathological state of the body. The human body is a unified whole, and the functional status of various tissues, organs, and systems will directly or indirectly affect the cardiovascular system, and the pulse wave is formed by the joint action of pressure pulsation and blood flow caused by the pulsating flow formed by the expansion and contraction of the heart. The information of each part of the body is transmitted to all parts of the body. By collecting the pulse wave and analyzing the characteristics of the information it carries, a judgment can be made on the overall state of the body. Pulse wave is an importa...

Problems solved by technology

[0004] In the prior art, after the face video image is collected and processed by a computer camera, the pulse signal obtained after processing can be compared with the standard pulse database for confrontation training, thereby obtaining a real-time detected pulse waveform. The video image processing process is not scientific and reasonable enough, resulting in the final output pulse waveform not accurately reflecting the real pulse signal of the tester, which affects the accuracy of the final judgment
