Bed exit monitoring system

1. A system for monitoring a patient in a bed, the system comprising:

multiple cameras in a vicinity of the bed;

a processor coupled wirelessly with the multiple cameras and including a memory device, the memory device including instructions that, when executed by the processor, cause the processor to:

process video data captured by the multiple cameras and pertaining to a position of the patient relative to the bed and analyze the video data to determine whether the patient is exiting the bed; and

pixilate the video data and highlight portions of an image of the patient to indicate that the patient is exiting the bed.

2. The system of claim 1 , wherein the memory device further includes instructions that, when executed by the processor, cause the processor to determine a risk of the patient exiting the bed.

3. The system of claim 1 , wherein the memory device further includes instructions that, when executed by the processor, cause the processor to output a signal indicative of the patient exiting the bed.

4. The system of claim 3 , wherein the signal comprises an alarm.

5. The system of claim 1 , wherein the memory device further includes instructions that, when executed by the processor, cause the processor to analyze a risk of a patient fall.

6. A method for monitoring a patient in a bed, the method comprising:

capturing images of the patient with multiple cameras in a vicinity of the bed;

transmitting the images of the patient from the multiple cameras to a processor including a memory device;

processing the images to provide processed image data pertaining to a position of the patient relative to the bed, the processing including:

pixilating the images, and

highlighting portions of the images of the patient to indicate that the patient is exiting the bed; and

analyzing the processed image data to determine whether the patient is exiting the bed.

7. The method of claim 6 , wherein the images comprise video images.

8. The method of claim 6 , wherein processing the images comprises:

dense sampling of the images in multiple spatial scales;

tracking in each of the multiple spatial scales separately; and

providing a trajectory description.

9. The method of claim 6 , wherein the analyzing step is performed by a user.

10. The method of claim 6 , further comprising providing an alarm indicating that the patient is exiting the bed.

11. The method of claim 6 , further comprising wirelessly transmitting the images of the patient from the multiple cameras to the processor.
