Systems and methods for video archive and data extraction
Systems and methods for full motion video search are provided. In one aspect, a method includes receiving one or more search terms. The search terms include one or more of a characterization of the amount of man-made features in a video image and a characterization of the amount of natural features in the video image. The method further includes searching a full motion video database based on the one or more search terms.
1. A method of adding a video entity to a full motion video database supporting search capabilities, the method comprising:
determining a starting cell in the full motion video database; and
determining if the starting cell should be split, and if the starting cell should be split:
splitting the starting cell to create two new child cells, and
adding the video entity to one of the two new child cells.
2. The method of claim 1 , wherein splitting the starting cell comprises splitting the starting cell along a split axis.
3. The method of claim 2 , wherein the split axis is along a line of latitude.
4. The method of claim 2 , wherein the split axis is along a line of longitude.
5. The method of claim 2 , wherein the two new child cells are created along the split axis.
6. The method of claim 1 , further comprising moving one or more video entities stored in the starting cell from the starting cell to the new child cells.
7. The method of claim 6 , further comprising adding pointers to the starting cell pointing to the child cells.
8. The method of claim 1 , wherein determining if the starting cell should be split comprises determining if the starting cell is full.
9. The method of claim 8 , further comprising adding the video entity to the starting cell if the starting cell not full.
10. The method of claim 1 , further comprising:
determining a child cell from a plurality of child cells of the starting cell if the starting cell contains a plurality of child cells; and
adding the video entity to one of the plurality of child cells.
11. The method of claim 10 , wherein the one of the plurality of child cells the video entity is added to is determined based on the video entity.
12. The method of claim 1 , further comprising if the starting cell contains a plurality of child cells:
determining a child cell from the plurality of child cells; and
adding the video entity to the full motion video database using the child cell as a starting cell.
