Abstract

Embodiments of the present invention may provide the capability to identify a specific object being interacted with that may be cheaply and easily included in mass-produced objects. In an embodiment, a computer-implemented method for object identification may comprise receiving a signal produced by a physical interaction with an object to be identified, the signal produced by an identification structure coupled to the object during physical interaction with the object, processing the signal to form digital data representing the signal, and accessing a database using the digital data to retrieve information identifying the object.

First claim

What is claimed is:

1. A computer-implemented method for object recognition comprising:
displaying a video or image in real-time;
displaying an interactive geometric shape adapted to be adjusted by a user to select an object in the displayed video or image;
obtaining an aspect ratio of the interactive geometric shape;
comparing the obtained aspect ratio to aspect ratios of a plurality of object templates;
identifying at least one object having an aspect ratio corresponding to the aspect ratio of the interactive geometric shape;
determining a resolution of the video or image based on the identified object.

2. The method of claim 1 , further comprising:
locating an object in the video or image by resizing the video or image to a scale based on the determined resolution.

3. The method of claim 1 , wherein identifying at least one object having an aspect ratio corresponding to the aspect ratio of the interactive geometric shape comprises:
identifying a plurality of objects having aspect ratios corresponding to the aspect ratio of the interactive geometric shape, wherein each of the plurality of identified objects has different dimensions; and
determining a plurality of different resolutions of the video or image based on the plurality of identified objects.

4. The method of claim 3 , further comprising:
locating an object in the video or image by resizing the video or image to a scale based on the determined plurality of different resolutions.

5. The method of claim 1 , further comprising:
setting an image processing parameter based on the determined resolution.

6. The method of claim 1 , wherein the determining a resolution of the video or image based on the identified object comprises:
reducing a space of possible resolutions by limiting the possible resolutions to resolutions corresponding to the identified at least one object.

7. The method of claim 1 , further comprising:
receiving from a user input including additional information about the object.

8. A computer program product for object recognition, the computer program product comprising a non-transitory computer readable storage having program instructions embodied therewith, the program instructions executable by a computer, to cause the computer to perform a method comprising:
displaying a video or image in real-time;
displaying an interactive geometric shape adapted to be adjusted by a user to select an object in the displayed video or image;
obtaining an aspect ratio of the interactive geometric shape;
comparing the obtained aspect ratio to aspect ratios of a plurality of object templates;
identifying at least one object having an aspect ratio corresponding to the aspect ratio of the interactive geometric shape; and
determining a resolution of the video or image based on the identified object.

9. The computer program product of claim 8 , further comprising program instructions for:
locating an object in the video or image by resizing the video or image to a scale based on the determined resolution.

10. The computer program product of claim 8 , wherein identifying at least one object having an aspect ratio corresponding to the aspect ratio of the interactive geometric shape comprises:
identifying a plurality of objects having aspect ratios corresponding to the aspect ratio of the interactive geometric shape, wherein each of the plurality of identified objects has different dimensions; and
determining a plurality of different resolutions of the video or image based on the plurality of identified objects.

11. The computer program product of claim 10 , further comprising program instructions for:
locating an object in the video or image by resizing the video or image to a scale based on the determined plurality of different resolutions.

12. The computer program product of claim 8 , further comprising program instructions for:
setting an image processing parameter based on the determined resolution.

13. The computer program product of claim 8 , wherein the determining a resolution of the video or image based on the identified object comprises:
reducing a space of possible resolutions by limiting the possible resolutions to resolutions corresponding to the identified at least one object.

14. The computer program product of claim 8 , further comprising program instructions for:
receiving from a user input including additional information about the object.

15. A system for object recognition, the system comprising a processor, memory accessible by the processor, and computer program instructions stored in the memory and executable by the processor to perform:
displaying a video or image in real-time;
displaying an interactive geometric shape adapted to be adjusted by a user to select an object in the displayed video or image;
obtaining an aspect ratio of the interactive geometric shape;
comparing the obtained aspect ratio to aspect ratios of a plurality of object templates;
identifying at least one object having an aspect ratio corresponding to the aspect ratio of the interactive geometric shape; and
determining a resolution of the video or image based on the identified object.

16. The system of claim 15 , further comprising program instructions for:
locating an object in the video or image by resizing the video or image to a scale based on the determined resolution.

17. The system of claim 15 , wherein identifying at least one object having an aspect ratio corresponding to the aspect ratio of the interactive geometric shape comprises:
identifying a plurality of objects having aspect ratios corresponding to the aspect ratio of the interactive geometric shape, wherein each of the plurality of identified objects has different dimensions; and
determining a plurality of different resolutions of the video or image based on the plurality of identified objects.

18. The system of claim 17 , further comprising program instructions for:
locating an object in the video or image by resizing the video or image to a scale based on the determined plurality of different resolutions.

19. The system of claim 15 , further comprising program instructions for:
setting an image processing parameter based on the determined resolution.

20. The system of claim 15 , wherein the determining a resolution of the video or image based on the identified object comprises:
reducing a space of possible resolutions by limiting the possible resolutions to resolutions corresponding to the identified at least one object.
