SYSTEM AND METHOD FOR EMBEDDING A PHYSIOLOGICAL SIGNAL INTO A VIDEO
First Claim
1. A method for embedding a physiological signal into a video, comprising:
- receiving a video of a subject;
receiving a time-varying signal corresponding to a physiological function of said subject;
obtaining a representative still image from said video;
replicating said representative image to generate a video sequence;
encoding segments of said received time-varying signal into said video sequence; and
compressing said video sequence using video compression.

Abstract
What is disclosed is a system and method for embedding a time-varying physiological signal corresponding to a physiological function of a subject into a video. In one embodiment, a video of a subject is received along with a time-varying signal corresponding to a physiological function of the subject. A representative image is obtained from the video. The received time-varying signal is divided into a plurality of signal segments. The obtained image is repeatedly replicated to generate a video sequence. The signal segments are encoded in the images comprising the generated video sequence. The video sequence containing the encoded physiological signal is then compressed using a video compression technique.
