Abstract

A system and method for computer vision based control of a device include a processor to track a human throughout a sequence of images of a space, to a location in the space, determine an identity of the human at the location in the space and if the human is at a predetermined location in the space, personalize operation of the device according to the identity of the human.

Claims

1. A method for controlling a device, the method comprising:

using a processor to

detect an object in at least one image of a space;

determine that the object is a human based on a shape of the object;

track the object throughout a sequence of images of the space, to a location in the space;

determine an identity of the human at the location in the space; and

generate a command to control parameters of the device operation if the object is at a predetermined location in the space and according to the identity of the human.

2. The method of claim 1 wherein the image of the space is a top view image of the space.

3. The method of claim 1 comprising using the processor to track features from within the object throughout the sequence of images of the space.

4. The method of claim 1 comprising using the processor to track an identified human to the location in the space.

5. The method of claim 1 wherein the predetermined location in the space comprises a location within a predetermined range from the device.

6. The method of claim 1 wherein the processor is to detect the object in a first image of the space and determine the identity of the human in a second image of the space.

7. The method of claim 1 wherein using the processor to determine the identity of the human comprises recognizing facial features of the human.

8. The method of claim 1 wherein the identity of the human comprises the human'"'"'s general characteristics.

9. The method of claim 1 wherein the identity of the human comprises specific features of the human.

10. The method of claim 1 wherein the command to control parameters of the device operation comprises a command to control the device according to a predetermined set of parameters.

11. The method of claim 1 wherein the device operation does not involve using images comprising the human.

12. The method of claim 1 wherein the device comprises an environment comfort device.

13. A system for computer vision based control of a device, the system comprising:

a processor in communication with an image sensor, the image sensor to obtain images of a space; and

with the device,

the processor configured to

track an object throughout a sequence of images of the space, to a location in the space;

determine an identity of the object at the location in the space; and

if the object is at a predetermined location in the space personalize operation of the device according to the identity of the object.

14. The system of claim 13 wherein the processor is to run a shape detection algorithm on the images of the space to determine that the object is a human.

15. The system of claim 13 wherein the processor is to apply a face recognition algorithm on the images of the space to determine the identity of the object.

16. The system of claim 13 wherein the processor is configured to detect the object in a first image of the space and identify the object in a second image of the space.

17. The system of claim 13 wherein the operation of the device does not involve using images comprising the object.

18. The system of claim 13 wherein the device comprises an environment comfort device.

19. The system of claim 13 wherein the image sensor is adapted to obtain top view images of the space.
