Abstract

A method for establishing baseline data for normalization in a physiological monitoring system which captures images of an individual in order to monitor the well being of the individual, including establishing the identity of an individual; assembling a set of personal data associated with the individual, including semantic data; using the semantic data to identify at least a portion of the wellness parameters to be monitored; acquiring images of the individual during separate capture events to establish baseline image-based wellness parameter data and baseline capture condition data for the individual and; using the baseline wellness parameter data and baseline capture condition data to monitor the physiological condition of the individual.

Claims

1. A method for establishing baseline data for normalization in a physiological monitoring system which captures images of an individual in order to monitor the well being of the individual, comprising;

establishing the identity of an individual;

assembling a set of personal data associated with the individual, including semantic data;

using the semantic data to identify at least a portion of the wellness parameters to be monitored;

acquiring images of the individual during separate capture events to establish baseline image-based wellness parameter data and baseline capture condition data for the individual and;

using the baseline wellness parameter data and baseline capture condition data to monitor the physiological condition of the individual.

2. The method of claim 1, further including taking into consideration lighting conditions during the capture events.

3. The method of claim 1, further including taking into consideration the pose of the individual during the capture events.

4. The method of claim 1, further including determining baseline normalization transforms.

5. The method of claim 4, further including determining baseline normalization confidence values, associated with the baseline normalization transforms.

6. The method of claim 1, wherein the baseline wellness parameter data includes images and image derived data.

7. The method of claim 6 wherein the baseline wellness parameter data includes data regarding reference features for the individual.

8. The method of claim 7 wherein the reference features include the whiteness of the sclera or the eye-to-eye distance of the individual.

9. The method of claim 1 wherein the baseline wellness parameter data or the baseline capture data is averaged over multiple capture events.

10. The method of claim 1 wherein the system is further operated during an auto set-up process to acquire non-image type data using non-image type sensing devices.

11. The method of claim 1 wherein the acquired images are used to establish a reference image.

12. The method of claim 11 wherein the reference image is used in the automatic assessment of the well being of the individual.

13. The method of claim 1 further including providing a subsequent set-up process including further image capture of the individual.

14. The method of claim 13, wherein the subsequent set-up process is initiated based upon semantic information that includes the individual'"'"'s age, the impact of prior physiological conditions, presence or absence of facial hair, seasonal factors, or environmental changes.

15. A method for establishing baseline data for a physiological monitoring system during an auto set-up process, which senses physiological data of an individual in order to monitor the well being of the individual, comprising;

establishing the identity of an individual;

assembling a set of personal data associated with the individual, including semantic data;

using the semantic data to identify at least a portion of the wellness parameters to be monitored;

operating the system during an auto set-up process to sense baseline temporal physiological data of the individual during at least one capture event, and acquiring baseline capture condition data associated with each capture event;

establishing baseline wellness parameter data from the baseline physiological data; and

using the baseline wellness parameter data and baseline capture condition data to monitor physiological conditions of the individual.

16. The method according to claim 15 further including using an image capture device to derive baseline temporal physiological data for the individual from video images.

17. The method according to claim 15 further including using a microphone to derive baseline temporal physiological data from vocal data produced by the individual.

18. The method of claim 15, wherein the auto set-up process determines baseline normalization transforms for the baseline temporal physiological data.
