Abstract

Methods and devices for selecting objects in images are described. In one example aspect, a method includes: receiving stereoscopic image data, the stereoscopic image data includes a first image obtained from a first camera and a second image obtained from a second camera; identifying an object in the first image by analyzing the first image and the second image; displaying the first image, the identified object in the first image being selectable.

First claim

The invention claimed is:

1. A method, implemented by a processor of an electronic device, for allowing selection of an object in an image, the method comprising:
receiving image data, the image data including a first image obtained from a first camera and a second image obtained from a second camera, the first camera and the second camera being oriented in a common direction;
identifying an object in the first image by analyzing the first image and the second image, wherein the analyzing includes identifying one or more boundary associated with the object in the first image based on discontinuities in one or more visual characteristics and based on depth information corresponding to the identified discontinuities; and
displaying the first image, the identified object in the first image being selectable.

2. The method of claim 1 , further comprising:
receiving a signal indicating a selection of the identified object; and
manipulating the first image based on the selection of the identified object.

3. The method of claim 2 , wherein manipulating includes cropping the identified object in the first image.

4. The method of claim 2 , wherein manipulating includes moving the identified object.

5. The method of claim 2 , wherein manipulating includes associating a caption with the identified object in the first image.

6. The method of claim 1 , further comprising:
receiving a signal indicating an instruction for copying the identified object; and
in response the instruction, copying the identified object to an application.

7. The method of claim 1 , wherein identifying one or more boundary includes performing image segmentation.

8. The method of claim 7 , wherein performing image segmentation includes using the second image to obtain depth information to identify the object in the first image.

9. The method of claim 1 , wherein the identified object in the first image is selectable based on the boundary identified in the analysis.

10. The method of claim 1 , wherein identifying one or more boundary includes performing edge detection.

11. The method of claim 8 , wherein performing edge detection includes using the second image to identify the image portions having discontinuities in the one or more visual characteristics, wherein the one or more visual characteristics includes at least one of illumination, colour, intensity, and texture.

12. The method of claim 1 , wherein the first image is displayed as a non-stereoscopic image.

13. The method of claim 1 , further comprising:
discarding the second image from the electronic device after analyzing the first image and the second image.

14. The method of claim 1 , wherein the image data is received in response to receiving an instruction to capture a non-stereoscopic image.

15. An electronic device comprising:
a memory;
a display;
a first camera and a second camera; and
a processor coupled to the memory, the display, the first camera, and the second camera, the processor being configured to:
receive image data, the image data including a first image obtained by the first camera and a second image obtained by the second camera, the first camera and the second camera being oriented in a common direction;
identify an object in the first image by analyzing the first image and the second image, wherein the analyzing includes identifying one or more boundary associated with the object in the first image based on discontinuities in one or more visual characteristics and based on depth information corresponding to the identified discontinuities; and
display the first image on the display, the identified object in the first image being selectable.

16. The electronic device of claim 15 , wherein the processor is further configured to:
receive a signal indicating selection of the identified object; and
manipulate the first image based on the selection of the identified object.

17. The electronic device of claim 16 , wherein manipulate includes crop the identified object in the first image.

18. The electronic device of claim 16 , wherein manipulate includes move the identified object.

19. The electronic device of claim 16 , wherein manipulate includes associate a caption with the identified object in the first image.

20. A non-transitory, tangible computer readable storage medium encoded with computer executable instructions, wherein execution of the computer executable instructions is for:
receiving image data, the image data including a first image obtained from a first camera and a second image obtained from a second camera, the first camera and the second camera being oriented in a common direction;
identifying an object in the first image by analyzing the first image and the second image, wherein the analyzing includes identifying one or more boundary associated with the object in the first image based on discontinuities in one or more visual characteristics and based on depth information corresponding to the identified discontinuities; and
displaying the first image, the identified object in the first image being selectable.
