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

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] refer to figure 1 , the present invention provides a method for displaying pulse waveform in real time based on human face video, comprising the following steps:

[0039] (1) Collect face video and standard pulse condition; use the smartphone's own camera or other imaging equipment to collect the subject's face video for 1 minute, use natural light as the light source during collection, try to ensure sufficient illumination in the face area, and at the same time be tested In order to realize the training of face pulse generation adversarial network, the standard pulse data is input while the face video is collected; the standard pulse waveform can be generated by standard Chinese medicine practitioners. After taking the pulse, it is generated by an algorithm, or the pulse waveform is collected by a calibrated standard pulse diagnostic instrument;

Abstract

The invention discloses a method and system for displaying pulse waveform in real time based on face video, comprising the following steps: (1) collecting face video and standard pulse condition; (2) detecting and regionally tracking the collected face video image; ( 3) Perform color space conversion; (4) Euler video amplification; (5) Separate RGB channels to generate initial pulse waves; (6) Denoise the initial pulse wave signals; (7) Pulse wave Hilbert‑ The Hilbert spectrum is obtained by Huang transformation; (8) Conditional generative adversarial network is constructed; (9) Conditional generative adversarial network is trained; (10) The pulse waveform is reconstructed. The present invention can intuitively display the pulse waveform only by collecting the video of the human face, which is convenient to use and has wide applicability.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and system for displaying pulse waveforms in real time based on face video. Background technique [0002] Human arteries are all over the body, and the pulse wave is an information window that reflects the physiological or pathological state of the body. The human body is a unified whole. The functional state of each tissue, organ, and system will directly or indirectly affect the cardiovascular system. The pulse wave is formed by the combined action of pressure pulsation and blood flow caused by the pulsating flow formed by the expansion and contraction of the heart. It spreads information from all parts of the body to all parts of the body. By collecting pulse waves and analyzing the information characteristics carried by them, the overall state of the body can be judged. Pulse wave is an important carrier of traditional Chinese medicine pulse diagnosis. Trad...
