Method and system for generating detail-in-context video presentations using a graphical user interface
View Patent ↗A method for generating a presentation of a region-of-interest in an image of a scene. The method includes the steps of capturing the image of the scene with a first camera and displaying the image of the scene on a display screen; selecting the region-of-interest within the image of the scene with a cursor and a pointing device; controlling a second camera to capture an image of a region of the scene corresponding to the region-of-interest; inserting the image of the region into the region-of-interest in the image of the scene to generate the presentation; and, displaying the presentation on the display screen.
1. A method for generating a presentation of a region-of-interest in an image of a scene comprising the steps of:
capturing said image of said scene with a first camera and displaying said image of said scene on a display screen;
selecting said region-of-interest within said image of said scene with a cursor and a pointing device;
controlling a second camera to capture an image of a region of said scene corresponding to said region-of-interest;
inserting said image of said region into said region-of-interest in said image of said scene to generate said presentation; and,
displaying said presentation on said display screen;
wherein said step of controlling further includes the steps of:
displaying a graphical user interface (“GUI”) over said region-of-interest on said display screen, wherein said GUI includes magnify, resize, and move areas;
zooming said second camera when said magnify area is selected and repositioned by said pointing device;
adjusting said second camera's field of view when said resize area is selected and repositioned by said pointing device; and,
panning and/or tilting said second camera when said move area is selected and repositioned by said pointing device;
wherein said region-of-interest has a focal region and a shoulder region surrounding said focal region;
wherein said resize area includes a first bounding shape surrounding said focal region, said first bounding shape having at least two active areas, said active areas for resizing said focal region by repositioning at least one of said active areas with said pointing device; and,
wherein said resize area further includes a second bounding shape surrounding said shoulder region, said second bounding shape having at least two active areas, said active areas for resizing said shoulder region by repositioning at least one of said active areas with said pointing device.
2. The method of claim 1 and further comprising the steps of:
creating a lens surface for said region-of-interest; and,
transforming said image of said region by applying a distortion function defining said lens surface to said image of said region.
3. The method of claim 1 wherein said active areas of said first bounding shape are for folding said focal region by repositioning at least one of said active areas with said pointing device.
4. The method of claim 1 wherein said GUI has a base outline, said base outline positioned within said second bounding shape, said base outline outlining said shoulder region.
5. The method of claim 4 wherein said magnify area is a slide bar, said slide bar having at least one active area, said active area for magnifying said region-of-interest by repositioning said active area with said pointing device.
6. The method of claim 5 wherein said move area has at least one active area, said move area located within said region-of-interest, said active area for moving said region-of-interest by repositioning said active area with said pointing device.
7. The method of claim 6 wherein said first and second bounding shapes are rectangles.
8. The method of claim 7 wherein one of said active areas is a corner-handle icon positioned over a corner of said first bounding shape.
9. The method of claim 8 wherein one of said active areas is a middle-handle icon positioned over said first bounding shape between corners of said first bounding shape.
10. The method of claim 9 wherein one of said active areas is a corner-handle icon positioned over a corner of said second bounding shape.
11. The method of claim 10 wherein one of said active areas is a middle-handle icon positioned over said second bounding shape between corners of said second bounding shape.
12. The method of claim 11 wherein said move area has at least one pickup point, said pickup point having at least one active area, said active area for moving said base outline and subsequently said region-of-interest by repositioning said active area with said pointing device.
13. The method of claim 12 wherein said pickup point is located centrally in said region-of-interest.
14. The method of claim 13 wherein said move area excludes said first bounding shape, said second bounding shape, and said pickup point.
15. The method of claim 14 wherein one of said active areas is a pickup icon positioned over said pickup point.
16. The method of claim 15 wherein one of said active areas is a bar icon positioned over said slide bar.
17. The method of claim 16 wherein said cursor changes shape when positioned over one of said active areas.
18. The method of claim 17 wherein said cursor chances said shape to a resize icon when positioned over said corner-handle icon or said middle-handle icon.
19. The method of claim 18 wherein said cursor changes said shape to a move icon when positioned over said move area.
20. The method of claim 1 wherein said pointing device is a mouse.
21. The method of claim 1 for use in a video camera security system.
22. The method of claim 1 wherein said region-of-interest, said second camera, and said image of said region are a plurality of regions-of-interest, a plurality of second cameras, and a plurality of images of said region, respectively.
