Abstract

A method for picture processing is described. A first tracking area is obtained. A second tracking area is also obtained. The method includes beginning to track the first tracking area and the second tracking area. Picture processing is performed once a portion of the first tracking area overlapping the second tracking area passes a threshold.

First claim

What is claimed is:

1 . A method, comprising:
tracking a first tracking area; tracking a second tracking area; determining, in a first frame, an amount of overlap between the first tracking area in the first frame and the second tracking area in the first frame; and performing picture processing in response to determining that the amount of overlap passes a threshold.

2 . The method of claim 1 , wherein the picture processing is performed once the amount of overlap becomes greater than the threshold.

3 . The method of claim 1 , wherein the picture processing is performed once the amount of overlap becomes less than the threshold.

4 . The method of claim 1 , wherein determining the amount of overlap is based on whether the first tracking area is larger than the second tracking area.

5 . The method of claim 1 , wherein the picture processing comprises capturing a photograph.

6 . The method of claim 5 , wherein the photograph is captured from live footage.

7 . The method of claim 1 , wherein the picture processing comprises editing a video sequence.

8 . The method of claim 7 , wherein editing the video sequence includes removing an object tracked within the first tracking area from the video sequence.

9 . The method of claim 8 , further comprising:
selecting a second frame of the video sequence, wherein the first tracking area does not overlap a corresponding replacement area in the second frame; and replacing the first tracking area in the first frame with the corresponding replacement area from the second frame.

10 . The method of claim 9 , wherein the second frame occurs later in time than the first frame.

11 . The method of claim 9 , wherein the second frame occurs earlier in time than the first frame.

12 . The method of claim 9 , further comprising:
storing the first frame as part of an edited video sequence.

13 . The method of claim 1 , further comprising receiving a first user selection of the first tracking area.

14 . The method of claim 13 , further comprising receiving a second user selection of the second tracking area.

15 . The method of claim 13 , wherein the first user selection is based on a shape.

16 . The method of claim 15 , wherein the shape is selected by a user.

17 . The method of claim 13 , wherein the first user selection is based on a selection of an object.

18 . The method of claim 1 , wherein a shape associated with at least one of the first tracking area and the second tracking area is changed based on a state of at least one of the first tracking area and the second tracking area.

19 . The method of claim 1 , wherein the second tracking area comprises an action line, wherein the amount of overlap passes the threshold upon the first tracking area crossing the action line.

20 . The method of claim 19 , wherein the action line is set by a user.

21 . A device, comprising:
a memory; and a processor coupled to the memory, the processor configured to:
track a first tracking area;
track a second tracking area;
determine, in a first frame, an amount of overlap between the first tracking area in the first frame and the second tracking area in the first frame; and
perform picture processing in response to determining that the amount of overlap passes a threshold.

22 . The device of claim 21 , wherein the picture processing is performed once the amount of overlap becomes greater than the threshold.

23 . The device of claim 21 , wherein the picture processing is performed once the amount of overlap becomes less than the threshold.

24 . The device of claim 21 , wherein determining the amount of overlap is based on whether the first tracking area is larger than the second tracking area.

25 . The device of claim 21 , wherein the picture processing comprises capturing a photograph.

26 . The device of claim 25 , wherein the photograph is captured from live footage.

27 . The device of claim 21 , wherein the picture processing comprises editing a video sequence.

28 . The device of claim 27 , wherein editing the video sequence includes removing an object tracked within the first tracking area from the video sequence.

29 . The device of claim 28 , wherein the processor is further configured to:
select a second frame of the video sequence, wherein the first tracking area does not overlap a corresponding replacement area in the second frame; and replace the first tracking area in the first frame with the corresponding replacement area from the second frame.

30 . The device of claim 29 , wherein the second frame occurs later in time than the first frame.

31 . The device of claim 29 , wherein the second frame occurs earlier in time than the first frame.

32 . The device of claim 29 , wherein the processor is further configured to:
store the first frame as part of an edited video sequence.

33 . The device of claim 21 , wherein the processor is further configured to:
receive a first user selection of the first tracking area.

34 . The device of claim 33 , wherein the processor is further configured to:
receive a second user selection of the second tracking area.

35 . The device of claim 33 , wherein the first user selection is based on a shape.

36 . The device of claim 35 , wherein the shape is selected by a user.

37 . The device of claim 33 , wherein the first user selection is based on a selection of an object.

38 . The device of claim 21 , wherein a shape associated with at least one of the first tracking area and the second tracking area is changed based on a state of at least one of the first tracking area and the second tracking area.

39 . The device of claim 21 , wherein the second tracking area comprises an action line, wherein the amount of overlap passes the threshold upon the first tracking area crossing the action line.

40 . The device of claim 39 , wherein the action line is set by a user.

41 . An apparatus, comprising:
means for tracking a first tracking area; means for tracking a second tracking area; means for determining, in a first frame, an amount of overlap between the first tracking area in the first frame and the second tracking area in the first frame; and means for performing picture processing in response to determining that the amount of overlap passes a threshold.

42 . A computer-program product, comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:
code for causing a device to track a first tracking area; code for causing the device to track a second tracking area; code for causing the device to determine, in a first frame, an amount of overlap between the first tracking area in the first frame and the second tracking area in the first frame; and code for causing the device to perform picture processing in response to determining that the amount of overlap passes a threshold.
