摘要
A paradoxical pulse determination method using an image includes the steps of: enabling a computer device to detect a skin area from the image composed of a plurality of frames; enabling the computer device to compute a mean value of color data of the skin area; enabling the computer device to separate an inspiration interval and an expiration interval from the mean value of the color data according to a time flow; enabling the computer device to extract a pulse wave signal from the mean value of the color data; and enabling the computer device to determine a paradoxical pulse based on a first value that is a frequency power mean value of the pulse wave signal in the inspiration interval and a second value that is a frequency power mean value of the pulse wave signal in the expiration interval. Accordingly, the present invention can easily determine the paradoxical pulse by using the image captured by a smart device.
