User interface for managing blur kernels

1. A computer-implemented method comprising:

displaying a graphical user interface configured to be used to deblur an image, the graphical user interface including a display zone and a control zone adjacent to the display zone;

displaying a user-selected image in the display zone;

displaying a suggested blur kernel in the control zone, the suggested blur kernel being associated with a blurred region in the user-selected image, wherein the suggested blur kernel is used to deblur the user-selected image; and

displaying the suggested blur kernel, proximate the associated blurred region in the display zone.

2. The method of claim 1 , wherein displaying the suggested blur kernel proximate the associated blurred region comprises overlaying the blur kernel on the blurred region.

3. The method of claim 1 , further comprising:

displaying a plurality of blur kernels in the control zone, each of the plurality of blur kernels being associated with a corresponding blurred region; and

displaying each of the plurality of blur kernels proximate its associated blurred region in the display zone.

4. The method of claim 1 , wherein the display zone defines a preview canvas for displaying changes to the user-selected image responsive to changes in one or more blur kernel parameters.

5. The method of claim 1 , wherein displaying the suggested blur kernel includes displaying a visualization of the blur kernel.

6. The method of claim 1 , further comprising:

displaying a blur boundary indicator on the user-selected image, the blur boundary indicator identifying a size of the blurred region; and

displaying a kernel boundary indicator on the user-selected image, the kernel boundary indicator identifying a size of an associated blur kernel, wherein the blur boundary indicator and the kernel boundary indicator show relative sizes of the blurred region and the blur kernel.

7. The method of claim 1 , further comprising a kernel size input feature configured to allow a user to modify at least one parameter of the blur kernel.

8. The method of claim 7 , wherein the at least one parameter is a size of the blur kernel, and the user-selected image in the display zone is modified in response to a variation in the at least one parameter.

9. The method of claim 1 , further comprising a kernel add feature configured to add further blur kernels, wherein upon selection of the kernel add feature a further blurred region of the user-selected image is identified in the display zone and an associated blur kernel is automatically determined.

10. The method of claim 1 , further comprising:

monitoring dragging of an object representative of a blur kernel to a blurred region in the display zone; and

automatically, without user input, determining a blur kernel for the blurred region.

11. The method of claim 10 , wherein the object representative of the blur kernel is located in the control zone.

12. The method of claim 1 , wherein a size of the suggested blur kernel is automatically estimated.

13. The method of claim 1 , wherein a size of the blur kernel is determined by operations comprising:

automatically, without user input, determining a first value for a first size for the blur kernel for the blurred region;

automatically, without user input, determining a second value for a second size for the blur kernel for the blurred region; and

determining a suggested size for the blur kernel based on the first value and the second value.

14. The method of claim 1 , wherein a plurality of blurred regions is identified in the user-selected image, the plurality of blurred regions corresponding to regions in the user-selected image where a number of edge orientations exceeds a threshold value.

15. The method of claim 14 , wherein a blur kernel is displayed in the control zone corresponding to each of the plurality of regions.

16. The method of claim 1 , wherein the user-selected image displayed in the display zone is updated when the blurred region is deconvolved with the blur kernel.

17. A display interface comprising:

an access module to access processing data related to deblurring an image; and

a display module configured by at least one processor to display a graphical user interface for deblurring the image, the display module configured to:

cause a display of a display zone and a control zone adjacent to the display zone;

displaying a user-selected image in the display zone;

displaying a suggested blur kernel in the control zone, the suggested blur kernel being associated with a blurred region in the user-selected image, wherein the suggested blur kernel is used to deblur the user-selected image, the suggested blur kernel being represented by a convolution matrix; and

displaying the suggested blur kernel, proximate the associated blurred region in the display zone.

18. The display interface of claim 17 , wherein displaying the suggested blur kernel proximate the associated blurred region comprises overlaying the blur kernel on the blurred region.

19. The display interface of claim 17 , wherein:

a plurality of blur kernels are displayed in the control zone, each of the plurality of blur kernels being associated with a corresponding blurred region; and

each of the plurality of blur kernels is located proximate its associated blurred region in the display zone.

20. A non-transitory computer-readable storage medium including instructions which, when executed by a computer, cause the computer to perform operations comprising:

causing a display of a graphical user interface that is used to deblur an image, the graphical user interface including a display zone configured to display an image having a blurred region and a control zone adjacent to the display zone;

generating a blur kernel for the blurred region of the image, wherein the blur kernel is used to deblur the user-selected image;

causing a display of a visual indicator proximate to the blurred region of the image that identifies the blurred region as being associated with the blur kernel; and

receiving input from a user indicating a desire to modify the blur kernel; and

in response to the input, enabling user modification of the blur kernel.
