Abstract

The present disclosure relates to systems and methods for decoding matrixed bar codes, such as Quick Response (“QR”) codes. In one implementation, system for decoding an intrinsic matrixed bar code may include an image-receiving device; at least one processor configured to execute instructions; and at least one memory storing the instructions. The instructions may be to perform operations including receiving an image using the image-receiving device; determining a grid for the image, the grid having a plurality of cells; selecting at least one cell of the grid as a candidate cell for containing an intrinsic matrixed bar code; extracting at least one intrinsic matrixed bar code located within the candidate cell; determining that the at least one extracted matrixed bar code is degraded; and repairing the at least one extracted matrixed bar code.

First claim

What is claimed is:

1. A system for embedding an intrinsic matrixed bar code within a video, comprising:
at least one processor configured to execute instructions; and
at least one memory storing the instructions to perform operations comprising:
receiving a video having plurality of frames;
selecting a subset of the frames for embedding one or more intrinsic matrixed bar codes;
selecting at least one frame preceding the subset of frames;
generating a first set of registration marks for the selected at least one preceding frame;
selecting coordinates on frames of the subset of frames;
overlaying the one or more bar codes on the selected coordinates;
generating a second set registration marks with the selected coordinates; and
overlaying the first set of registration marks on corresponding frames of the selected at least one preceding frame and the second set of registration marks on corresponding frames of the subset of frames.

2. The system of claim 1 , wherein the operations further comprise dividing the received video into the plurality of frames.

3. The system of claim 1 , wherein the operations further comprise receiving an input and generating the one or more bar codes to encode the received input.

4. The system of claim 3 , wherein the input comprises a target location of digital content.

5. The system of claim 4 , wherein the input comprises a URL of the digital content.

6. The system of claim 1 , wherein the operations further comprise generating the one or more bar codes such that a notification will be sent to a third party when the one or bar codes are decoded.

7. The system of claim 1 , wherein the operations further comprise color-shifting pixels of the subset of frames surrounding the overlaid matrixed bar codes.

8. The system of claim 1 , wherein overlaying the one or more bar codes comprises applying a transparency to the one or more bar codes.

9. The system of claim 1 , wherein overlaying the one or more bar codes comprises reducing a size of the one or more bar codes.

10. The system of claim 9 , wherein selecting the coordinates comprises selecting the coordinates based on a color variance of an area including the selected coordinates.

11. A system for embedding an intrinsic matrixed bar code within a video, comprising:
at least one processor configured to execute instructions; and
at least one memory storing the instructions to perform operations comprising:
receiving a video having a plurality of frames encoded as a progressive scan,
selecting a subset of the frames for embedding one or more intrinsic matrixed bar codes,
selecting at least one frame preceding the subset of frames,
generating a first set of registration marks for the selected at least one preceding frame,
selecting coordinates on frames of the subset of frames,
encoding the at least one or more bar codes within the progressive scan such that the one or more bar codes will appear on the selected coordinates during painting,
generating a second set registration marks with the selected coordinates, and
encoding the first set of registration marks within the progressive scan such that the first set of registration marks will appear on corresponding frames of the selected at least one preceding frames during painting and encoding the second set registration marks within the progressive scan such that the second set of registration marks will appear on corresponding frames of the subset of frames during painting.

12. The system of claim 11 , wherein the operations further comprise dividing the received video into the plurality of frames.

13. The system of claim 11 , wherein the operations further comprise receiving an input and generating the one or more bar codes to encode the received input.

14. The system of claim 13 , wherein the input comprises a target location of digital content.

15. The system of claim 14 , wherein the input comprises a target location of digital content.

16. The system of claim 11 , wherein the operations further comprise generating the one or more bar codes such that a notification will be sent to a third party when the one or bar codes are decoded.

17. The system of claim 11 , wherein the operations further comprise color-shifting pixels of the subset of frames surrounding the overlaid matrixed bar codes.

18. The system of claim 11 , wherein overlaying the one or more bar codes comprises applying a transparency to the one or more bar codes.

19. The system of claim 11 , wherein overlaying the one or more comprises reducing a size of the one or more bar codes.

20. The system of claim 11 , wherein selecting the coordinates based on a color variance of an area including the selected coordinates.
