Abstract

Methods, systems, and products are disclosed recognizing gestures. A sequence of images is captured by a camera and compared to a stored sequence of images in memory. A gesture is then recognized in the stored sequence of images.

Claims

1. A method, comprising:

receiving, by a processor, a video signal corresponding to a stream of images captured by a camera;

retrieving, from memory, a set of gesture images;

comparing, by the processor, the stream of images in the video signal to the set of gesture images; and

determining, by the processor, an image in the stream of images matches a gesture image of a gesture in the set of gesture images.

2. The method of claim 1, further comprising sampling the video signal.

3. The method of claim 2, further comprising forming a sequence of images from the sampling.

4. The method of claim 1, further comprising associating the set of gesture images to an appliance.

5. The method of claim 1, further comprising associating the gesture image to an appliance.

6. The method of claim 1, further comprising associating the set of gesture images to an operation.

7. The method of claim 1, further comprising associating the gesture image to an operation.

8. A system, comprising:

a processor; and

a memory storing code that when executed causes the processor to perform operations, the operations comprising;

receiving a video signal corresponding to a stream of images captured by a camera;

retrieving a set of gesture images;

comparing the stream of images in the video signal to the set of gesture images; and

determining an image in the stream of images matches a gesture image of a gesture in the set of gesture images.

9. The system of claim 8, wherein the operations further comprise sampling the video signal.

10. The system of claim 9, wherein the operations further comprise forming a sequence of images from the sampling.

11. The system of claim 8, wherein the operations further comprise associating the set of gesture images to an appliance.

12. The system of claim 8, wherein the operations further comprise associating the gesture image to an appliance.

13. The system of claim 8, wherein the operations further comprise associating the set of gesture images to an operation.

14. The system of claim 8, wherein the operations further comprise associating the gesture image to an operation.

15. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:

receiving a video signal corresponding to a stream of images captured by a camera;

retrieving a set of gesture images from the memory;

comparing, by the processor, the stream of images in the video signal to the set of gesture images; and

determining an image in the stream of images matches a gesture image of a gesture in the set of gesture images.

16. The memory of claim 15, wherein the operations further comprise sampling the video signal.

17. The memory of claim 16, wherein the operations further comprise forming a sequence of images from the sampling.

18. The memory of claim 15, wherein the operations further comprise associating the set of gesture images to an appliance.

19. The memory of claim 15, wherein the operations further comprise associating the gesture image to an appliance.

20. The memory of claim 15, wherein the operations further comprise associating the gesture image to an operation.
