Abstract
A system and method for monitoring one or more physiological parameters of a subject under free-living conditions is provided. The system includes a camera configured to capture and record a video sequence including at least one image frame of at least one region of interest (ROI) of the subject's body. A computer in signal communication with the camera to receive signals transmitted by the camera representative of the video sequence includes a processor configured to process the signals associated with the video sequence recorded by the camera and a display configured to display data associated with the signals.
Claims20
A system for monitoring one or more physiological parameters of a subject under free-living conditions, the system comprising:
- a camera configured to capture and record a video sequence including at least one image frame of at least one region of interest (ROI) of the subject's body;
- and
- a computer in signal communication with the camera to receive signals transmitted by the camera representative of the video sequence, the computer including a processor configured to process the signals associated with the video sequence recorded by the camera, and a display configured to display data associated with the signals.
A method for monitoring a breathing pattern of a subject, the method comprising:
- selecting a region of pixels around an edge of each shoulder of the subject to be the regions of interest (ROIs);
- determining a derivative of the ROIs along a vertical direction to obtained two differential images of the ROIs;
- determining a position of each shoulder by dividing a differential image of each selected ROI into a top portion and an equal bottom portion along the edge of the shoulder, wherein an intensity of the top portion is dA and an intensity of the bottom portion is dB;
- and
- determining a vertical movement of each shoulder for every frame of the video sequence.
