Abstract

Methods, systems, computer-readable media, and apparatuses for image-based status determination are presented. In some embodiments, a method includes capturing at least one image of a moving path. At least one feature within the at least one image is analyzed and based on the analysis of the at least one feature, a direction of movement of the moving path is determined. In some embodiments, a method includes capturing an image of an inclined path. At least one feature within the image is analyzed and based on analysis of the at least one feature, a determination is made whether the image was captured from a top position relative to the inclined path or a bottom position relative to the inclined path.

Claims

1. A method for image-based status determination, comprising:

capturing, via a mobile device, at least one image of a moving path;

analyzing, via the mobile device, at least one feature within the at least one image;

based on analysis of the at least one feature, determining, via the mobile device, a direction of movement of the moving path; and

displaying, on a display of the mobile device, an advertisement along the moving path within a representation of the captured image based on the determined direction of movement of the moving path.

2. The method of claim 1 wherein the at least one feature comprises a body part of a person on the moving path.

3. The method of claim 1 wherein the at least one feature comprises an object adjacent to the moving path.

4. The method of claim 1 further comprising tracking and comparing the at least one feature between a plurality of the images.

5. The method of claim 1 further comprising displaying navigation directions on the mobile device based on the determined direction of movement of the moving path.

6. An apparatus for image-based status determination, comprising:

an image capture device configured to capture at least one image of a moving path;

a processor and a display device coupled to the image capture device;

the processor configured to;

analyze at least one feature within the at least one image;

determine a direction of movement of the moving path based on analysis of the at least one feature; and

command display, on the display device, of an advertisement along the moving path within a representation of the captured image based on the determined direction of movement of the moving path.

7. The apparatus of claim 6 wherein the at least one feature comprises a body part of a person on the moving path.

8. The apparatus of claim 6 wherein the at least one feature comprises an object adjacent to the moving path.

9. The apparatus of claim 6 wherein the processor is further configured to track and compare the at least one feature between a plurality of the images.

10. The apparatus of claim 6 wherein the processor is further configured to display navigation directions on the mobile device based on the determined direction of movement of the moving path.

11. An apparatus for image-based status determination, comprising:

means for capturing at least one image of a moving path;

means for analyzing at least one feature within the at least one image;

means for, based on analysis of the at least one feature, determining a direction of movement of the moving path; and

means for displaying an advertisement along the inclined path within a representation of the captured image based on the determined position from where the image was captured.

12. A processor-readable medium comprising processor-readable instructions configured to cause a processor to:

capture at least one image of a moving path;

analyze at least one feature within the at least one image;

based on analysis of the at least one feature, determine a direction of movement of the moving path; and

command display, on a display device, of an advertisement along the inclined path within a representation of the captured image based on the determined position from where the image was captured.

13. A method for image-based status determination, comprising:

capturing, via a mobile device, an image of an inclined path;

analyzing, via the mobile device, at least one feature within the image;

based on analysis of the at least one feature, determining, via the mobile device, whether the image was captured from a top position relative to the inclined path or bottom position relative to the inclined path; and

displaying, on a display of the mobile device, an advertisement along the inclined path within a representation of the captured image based on the determined position from where the image was captured.

14. The method of claim 13 wherein the determining step comprises detecting an object adjacent to the inclined path and determining an angle of the object with respect to a horizon line.

15. The method of claim 13 further comprising determining a tilt angle of a device used to capture the image, and wherein determination of whether the image was from a top position or bottom position is further based on the tilt angle.

16. The method of claim 13 further comprising displaying navigation directions on the mobile device based on the determined position from where the image was captured.

17. An apparatus for image-based status determination, comprising:

an image capture device configured to capture at least one image of an inclined path;

a processor and a display device coupled to the image capture device;

the processor configured to;

analyze at least one feature within the image; and

determine whether the image was captured from a top position relative to the inclined path or bottom position relative to the inclined path based on analysis of the at least one feature; and

command display, on the display device, of an advertisement along the inclined path within a representation of the captured image based on the determined position from where the image was captured.

18. The apparatus of claim 17 wherein the determining step comprises detecting an object adjacent to the inclined path and determining an angle of the object with respect to a horizon line.

19. The apparatus of claim 17 wherein the processor is further configured to determine a tilt angle of a device used to capture the image, and wherein determination of whether the image was from a top position or bottom position is further based on the tilt angle.

20. The apparatus of claim 17 wherein the processor is further configured to display navigation directions on the mobile device based on the determined position from where the image was captured.

21. An apparatus for image-based status determination, comprising:

means for capturing an image of an inclined path;

means for analyzing at least one feature within the image;

means for, based on analysis of the at least one feature, determining whether the image was captured from a top position relative to the inclined path or bottom position relative to the inclined path; and

means for displaying an advertisement along the inclined path within a representation of the captured image based on the determined position from where the image was captured.

22. A processor-readable medium comprising processor-readable instructions configured to cause a processor to:

capture an image of an inclined path;

analyze at least one feature within the image;

based on analysis of the at least one feature, determine whether the image was captured from a top position relative to the inclined path or bottom position relative to the inclined path; and

command display, on a display device, of an advertisement along the inclined path within a representation of the captured image based on the determined position from where the image was captured.
