Abstract

The invention discloses an information processing method, and the method comprises the steps: determining an identification region of an interested face corresponding to a frame image based on the frame image containing the face information of a to-be-detected object; performing spatial pixel averaging on at least two primary color channels of the identification area to obtain an identification signal of the identification area, and determining an identification signal curve based on the identification signal of the identification area; performing linear selection and blind source separation on the identification signal curve to obtain a target signal curve; wherein the target signal curve represents the heart rate of the to-be-detected object; and processing the target signal curve basedon signal transformation and a preset threshold to obtain a heart rate value of the to-be-detected object. The embodiment of the invention further discloses a terminal and a computer readable storagemedium.

Description

technical field [0001] The present invention relates to the technical field of digital image processing, in particular to an information processing method, a terminal and a computer-readable storage medium. Background technique [0002] Heart rate is one of the most important physiological information of the human body, which can reflect many important physiological signs of the human body, such as health status, etc.; in related technologies, non-contact human heart rate measurement has become a reality with the development of visual technology, and based on the face The non-contact human heart rate measurement of video has been widely concerned; and in the related technology, motion artifacts are prone to appear in the process of non-contact heart rate measurement based on face video, which easily leads to the user's non-contact heart rate measurement based on face video. There is a problem of low accuracy in heart rate measurement. Contents of the invention [0003] In...
