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.
Claims21
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.
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.
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.
