1. A method to mark a region in a graphical presentation, the method comprising:
- identifying, with a processor, a plurality of user-selected points selected in the graphical presentation with an input device;
determining, with the processor, that the plurality of user-selected points defines a boundary of the region;
responsive to a first user input received prior to or during selection of the plurality of user-selected points with the input device, comparing, with the processor, a plurality of stored templates with the plurality of user-selected points to identify a first one of the stored templates to mark the region; and
displaying, in the graphical presentation, the first one of the stored templates identified by the processor based on the comparing of the plurality of the stored templates with the plurality of user-selected points, prior to the first one of the stored templates being accepted for marking the region.

Abstract
Methods and apparatus to specify regions of interest in video frames are disclosed. Example disclosed methods to mark a region in a graphical presentation include selecting a first point located at a substantially central position within the region, selecting a plurality of second points to define a boundary of the region, and comparing a plurality of stored templates with the selected first and second points to identify a first one of the stored templates to represent the region.

7. A computer readable storage device or storage disk comprising computer readable instructions which, when executed, cause a computer to at least:
-
identify a plurality of user-selected points selected in a graphical presentation with an input device; determine that the plurality of user-selected points defines a boundary of a region to be marked in the graphical presentation; responsive to a first user input received prior to or during selection of the plurality of user-selected points, compare a plurality of stored templates with the plurality of user-selected points to identify a first one of the stored templates to mark the region; and display, in the graphical presentation, the first one of the stored templates identified by the computer based on the comparison of the plurality of the stored templates with the plurality of user-selected points, prior to the first one of the stored templates being accepted for marking the region. - View Dependent Claims (8, 9, 10, 11, 12, 20)

13. An apparatus to mark a region in a graphical presentation, the apparatus comprising:
-
an input device; a processor to; identify a plurality of user-selected points selected with the input device in the graphical presentation; determine that the plurality of user-selected points defines a boundary of the region; responsive to a first user input received prior to or during selection of the plurality of user-selected points, compare a plurality of stored templates with the plurality of user-selected points to identify a first one of the stored templates to mark the region; and display, in the graphical presentation, the first one of the stored templates identified by the processor based on the comparison of the plurality of the stored templates with the plurality of user-selected points, prior to the first one of the stored templates being accepted for marking the region; and memory to store the plurality of stored templates. - View Dependent Claims (14, 15, 16, 17, 18, 21)
