Abstract

Disclosed is a method for determining a region of interest (ROI) from an image. The method includes obtaining a wearing portion of a first electronic device, obtaining a first image related to a user wearing the first electronic device, and determining the ROI from the first image based on the obtained wearing portion.

Claims

1. A method for determining a region of interest (ROI), comprising:

obtaining a wearing portion of a first electronic device;

obtaining a first image related to a user wearing the first electronic device; and

determining the ROI from the first image based on the obtained wearing portion.

2. The method of claim 1, wherein obtaining the wearing portion includes determining the wearing portion based on the first electronic device and association information on a wearing portion corresponding to the first electronic device.

3. The method of claim 1, wherein obtaining the wearing portion includes determining the wearing portion by receiving information on the wearing portion determined from the first electronic device or based on sensed data received from the first electronic device.

4. The method of claim 1, wherein determining the ROI includes:

detecting at least one region corresponding to the wearing portion from the first image; and

determining the ROI corresponding to the detected at least one region.

5. The method of claim 1, further comprising obtaining motion information on the first electronic device.

6. The method of claim 5, wherein determining the ROI includes determining the ROI corresponding to the first electronic device when the first electronic device moves outside of a pre-determined threshold.

7. The method of claim 5, wherein the ROI is determined based on the obtained motion information and the wearing portion.

8. The method of claim 1, further comprising obtaining first information detected by the first electronic device.

9. The method of claim 8, wherein the ROI is determined based on the wearing portion and a type of the first information.

10. The method of claim 8, further comprising:

obtaining the second information by processing the ROI; and

obtaining third information based on the first information and the second information.

11. The method of claim 1, further comprising executing a first application using a result of processing the ROI, wherein the ROI is determined based on the wearing portion and data from the first application.

12. The method of claim 1, further comprising:

detecting a change of a wearing portion of the first electronic device; and

re-determining the ROI based on the changed wearing portion.

13. The method of claim 1, further comprising:

detecting another region in the image that is related to the ROI; and

additionally including the another detected region as another ROI.

14. An apparatus for determining a region of interest (ROI), comprising:

an image-obtaining module that obtains a first image related to a user wearing a first electronic device; and

a processing module that obtains a wearing portion of the first electronic device and determines the ROI from the first image.

15. The apparatus of claim 14, wherein the processing module determines the wearing portion based on the first electronic device and association information of a wearing portion corresponding to the first electronic device.

16. The apparatus of claim 14, further comprising a communication module that receives at least one of information on the wearing portion determined from the first electronic device or sensed data, wherein the processing module determines the wearing portion based on the received information on the wearing portion or the received sensed data.

17. The apparatus of claim 14, wherein the processing module detects at least one region corresponding to the wearing portion from the first image and determines the ROI corresponding to the detected at least one region.

18. The apparatus of claim 14, wherein the processing module obtains motion information on the first electronic device.

19. The apparatus of claim 18, wherein the processing module determines the ROI corresponding to the first electronic device when the first electronic device moves outside of a pre-determined threshold.

20. A method for determining a region of interest (ROI), the method comprising:

obtaining a first image related to a user wearing at least one electronic device;

obtaining a wearing portion of each of the at least one electronic device; and

determining the ROI of the first image using a wearing portion of a first electronic device from which a motion is detected among the at least one electronic device.
