Patent Images
1. A method, comprising:
- analyzing, by executing an instruction using a processor, a first aerial image of a first geographic area to detect a first plurality of objects;
generating, by executing an instruction using the processor, a first signature based on the first plurality of objects;
analyzing, by executing an instruction using the processor, a second aerial image of a second geographic area to detect a second plurality of objects;
reducing an uncertainty of estimated demographics in the first geographic area by;
associating, by executing an instruction using the processor, first demographic information to the second plurality of objects, the first demographic information determined based on ground truth data associated with the second geographic area, the ground truth data obtained by a sampling of the second geographic area;
generating, by executing an instruction using the processor, a second signature based on the second plurality of objects;
comparing, by executing an instruction using the processor, the second signature to the first signature; and
estimating, by executing an instruction using the processor, second demographic information of the first geographic area based on the comparison and the first demographic information.

Abstract
Methods and apparatus to estimate demography based on aerial images are disclosed. An example method includes analyzing a first aerial image of a first geographic area to detect a first plurality of objects, analyzing a second aerial image of a second geographic area to detect a second plurality of objects, associating first demographic information to the second plurality of objects, the first demographic information obtained by a sampling of the second geographic area, and comparing the second plurality of objects to the first plurality of objects to estimate a demographic characteristic of the first geographic area based on the comparison.

9. An apparatus, comprising:
-
an object detector to; analyze a first aerial image of a first geographic area to detect a first plurality of objects in the first geographic area; analyze a second aerial image of a second geographic area different than the first geographic area to detect a second plurality of objects in the second geographic area; generate a first signature based on the first plurality of objects; and generate a second signature based on the second plurality of objects; a database to associate first demographic information to the second plurality of objects, the first demographic information determined based on ground truth data associated with the second geographic area, the ground truth data obtained by sampling of the second geographic area; and a demography estimator to reduce an uncertainty of estimated demographics in the first geographic area by estimating second demographic information of the first geographic area based on the first demographic information and on a comparison of the second signature to the first signature. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A tangible computer readable storage medium comprising computer readable instructions which, when executed, cause a processor to at least:
-
analyze a first aerial image of a first geographic area to detect a first plurality of objects; analyze a second aerial image of a second geographic area to detect a second plurality of objects; generate a first signature based on the first plurality of objects; and reduce an uncertainty of estimated demographics in the first geographic area by; associating first demographic information to the second plurality of objects, the first demographic information determined based on ground truth data associated with the second geographic area, the ground truth data obtained by sampling of the second geographic area; generating a second signature based on the second plurality of objects; comparing the second signature to the first signature; and estimating second demographic information of the first geographic area based on the comparison and the first demographic information. - View Dependent Claims (17, 18, 19, 20, 21, 22)
