Abstract

Some embodiments provide an image editing application that edits an image. The image editing application assigns a mask value to each pixel of the image that includes several pixels. The mask value for a pixel is for using when processing the pixel. The image editing application displays the image in a display area. The image editing application receives several user inputs on a set of pixels of the image. The image editing application incrementally applies an image processing operation to the set of pixels by changing the mask values for the set of pixels each time the set of pixels receives a user input.

Claims

1. A non-transitory machine readable medium storing a program which when executed by at least one processing unit provides a graphical user interface (GUI) for editing an image, the GUI comprising:

a display area for displaying an image comprising a plurality of pixels;

a tool for (i) receiving a touch input that moves across a set of pixels of an image as a plurality of successive movements, (ii) identifying a first subset of the set of pixels over which the touch input initially moves, (iii) determining a set of similarity criteria for identifying pixels similar to the first subset of pixels, and (iv) applying an image processing operation only to a second subset of the set of pixels over which the touch input moves that satisfy the similarity criteria, wherein the image processing operation is not applied to pixels in the set of pixels over which the touch input moves that do not meet the similarity criteria.

2. The non-transitory machine readable medium of claim 1, wherein the set of similarity criteria includes whether pixels have pixel values that fall within a range of pixel values of the first subset of pixels.

3. The non-transitory machine readable medium of claim 1, wherein the tool incrementally increases application of the image processing operation each time the touch input moves over pixels in the second subset of pixels.

4. The non-transitory machine readable medium of claim 3, wherein the tool applies a different amount of modification to a particular pixel in the second subset of pixels with each successive movement over the particular pixel.

5. The non-transitory machine readable medium of claim 1, wherein the touch input is a rubbing touch input.

6. A non-transitory machine readable medium storing a program for execution by at least one processing unit, the program comprising sets of instructions for:

displaying an image in a display area, the image comprising a plurality of pixels;

receiving a touch input that moves across a set of pixels in an area of the image as a plurality of successive swipe movements;

determining, based on properties of a subset of pixels in the area of the image over which a first of the successive swipe movements of the touch input initially moves, a set of criteria for identifying pixels similar to the pixels in the subset of pixels; and

applying an image processing operation only to the pixels over which the touch input moves that satisfy the identified criteria, wherein the image processing operation is not applied to pixels in the set of pixels over which the touch input moves that do not meet the identified criteria.

7. The non-transitory machine readable medium of claim 6, wherein the set of instructions for determining the set of criteria comprises a set of instructions for converting pixel values of the pixels in the subset of pixels from RGB color model values to LAB space values.

8. The non-transitory machine readable medium of claim 7, wherein the set of instructions for determining the set of criteria further comprises a set of instructions for determining whether a pixel in the area is within a predefined distance from the subset of pixels.

9. The non-transitory machine readable medium of claim 6, wherein the set of instructions for applying the image processing operation to the pixels over which the touch input moves that satisfy the identified criteria comprises a set of instructions for incrementally increasing the application of the image processing operation to a particular group of the pixels with each successive swipe movement over the particular group of pixels.

10. The non-transitory machine readable medium of claim 9, wherein an amount of modification to the particular group of pixels with a first of the successive swipe movements is different than an amount of modification with a second of the successive swipe movements.

11. The non-transitory machine readable medium of claim 9, wherein the set of instructions for incrementally increasing the application of the effect comprises a set of instructions for linearly increasing an amount of the image processing operation applied with each one of the successive swipe movements over the particular group of pixels.

12. An electronic device comprising:

a set of processing units; and

a non-transitory machine readable medium storing a program which when executed by at least one of the processing units provides a graphical user interface (GUI) for editing an image, the GUI comprising;

a display area for displaying an image comprising a plurality of pixels; and

a tool for (i) receiving a touch input that moves across a set of pixels of an image as a plurality of successive movements, (ii) identifying a first subset of the set of pixels over which the touch input initially moves, (iii) determining a set of similarity criteria for identifying pixels similar to the first subset of pixels, and (iv) applying an image processing operation only to a second subset of the set of pixels over which the touch input moves that satisfy the similarity criteria, wherein the image processing operation is not applied to pixels in the set of pixels over which the touch input moves that do not meet the similarity criteria.

13. The electronic device of claim 12, wherein the set of similarity criteria includes whether pixels have pixel values that fall within a range of pixel values of the first subset of pixels.

14. The electronic device of claim 12, wherein the tool incrementally increases application of the image processing operation each time the touch input moves over pixels in the second subset of pixels.

15. The electronic device of claim 14, wherein the tool applies a different amount of modification to a particular pixel in the second subset of pixels with each successive movement over the particular pixel.

16. The non-transitory machine readable medium of claim 12, wherein the touch input is a rubbing touch input.

17. A method comprising:

displaying an image in a display area, the image comprising a plurality of pixels;

receiving a touch input that moves across a set of pixels in an area of the image as a plurality of successive swipe movements;

determining, based on properties of a subset of pixels in the area of the image over which a first of the successive swipe movements of the touch input initially moves, a set of criteria for identifying pixels similar to the pixels in the subset of pixels; and

applying an image processing operation only to the pixels over which the touch input moves that satisfy the identified criteria, wherein the image processing operation is not applied to pixels in the set of pixels over which the touch input moves that do not meet the identified criteria

wherein the displaying, receiving, determining, and applying are performed by an electronic device.

18. The method of claim 17, wherein determining the set of criteria comprises converting pixel values of the pixels in the subset of pixels from RGB color model values to LAB space values.

19. The method of claim 18, wherein determining the set of criteria further comprises determining whether a pixel in the area is within a predefined distance from the subset of pixels.

20. The method of claim 17, wherein applying the image processing operation to the pixels over which the touch input moves that satisfy the identified criteria comprises incrementally increasing the application of the image processing operation to a particular group of the pixels with each successive swipe movement over the particular group of pixels.

21. The method of claim 20, wherein an amount of modification to the particular group of pixels with a first of the successive swipe movements is different than an amount of modification with a second of the successive swipe movements.

22. The method of claim 20, wherein incrementally increasing the application of the effect comprises linearly increasing an amount of the image processing operation applied with each one of the successive swipe movements over the particular group of pixels.
