Pulmonary function measurement and respiratory status diagnosis method using the respiratory curve detected from the face image

摘要

Methods for measuring lung function and diagnosing respiratory conditions using a breath curve detected in a face image include detecting a skin region in the captured image, detecting a breath curve in the detected skin region, and detecting positive and negative in the detected breath curve. Detecting the peak point of, and distinguishing the inhalation and exhalation, calculating the parameters using the detected peak point, measuring and measuring the lung function using the parameters and changes in the height of the exhalation and exhalation section And diagnosing a respiratory condition using the calculated lung function and the calculated parameters.
