Method and system for monitoring breathing activity of a subject
First Claim
Patent Images
1. A method of monitoring a subject, comprising:
- using an optical device to obtain an image of the subject;
analyzing the image to determine a number of marker(s);
comparing the number of marker(s) with a prescribed value; and
generating a signal when the number of marker(s) is less than the prescribed value, wherein the signal is generated when the number of marker(s) is less than the prescribed value, and when a lost marker cannot be reacquired in two or more consecutive image frames.
