Abstract

Images from checks may be compared with each other to detect a twice-deposited or represented check. An image of a check may be parsed into regions or tiles, for example. In an implementation, values for regions or tiles over a predetermined area (e.g., an area from a character in the magnetic ink character recognition (MICR) line at the bottom of the check to the dollar sign symbol) may be compared. In an implementation, a virtual overlay of two check images may be performed and a correlation may be determined.

Claims

1. A non-transitory computer-readable medium comprising computer-readable instructions for duplicate check detection, said computer-readable instructions comprising instructions for causing a processor to:

receive a first image corresponding to an image of a first check;

receive a second image corresponding to an image of a second check; and

compare the first image and the second image to determine if the first check is a duplicate of the second check, wherein the computer readable instructions to compare the first image and the second image comprise instructions to;

determine a plurality of regions or tiles on each of the first image and the second image around a center of a line of sight determined between coordinates of a first feature and a second feature in each of the first and second images; and

compare a value for each of the plurality of regions or tiles in each of the first and second images.

2. The computer-readable medium of claim 1, wherein one of the first point or the second point is associated with a magnetic ink character recognition (MICR) line on each of the first check and the second check.

3. The computer-readable medium of claim 1, further comprising instructions that isolate an additional feature on each of the first image and the second image, wherein the instructions that compare the first image and the second image further comprise instructions that compare the additional feature of the first image and the additional feature of the second image.

4. The computer readable medium of claim 1, wherein the instructions to compare a value for each of the plurality of regions or tiles comprises instructions to associate a respective value to each of the plurality of regions or tiles based on a mathematical analysis of each region or tile of each of the first and second images.

5. The computer readable medium of claim 4, wherein the mathematical analysis comprises a Fourier analysis.

6. A duplicate check detection method, comprising, in a processor:

receiving a first image corresponding to an image of a first check;

receiving a second image corresponding to an image of a second check;

and comparing the first image and the second image to determine if the first check is a duplicate of the second check, wherein comparing the first image and the second image comprises;

determining a plurality of regions or tiles on each of the first image and the second image around a center of a line of sight determined between coordinates of a first feature and second feature in each of the first and second images; and

comparing a value for each of the plurality of regions or tiles in each of the first and second images.

7. The method of claim 6, wherein one of the first point or the second point two points is associated with a magnetic ink character recognition (MICR) line on each of the first check and the second check.

8. The method of claim 6, further comprising isolating an additional feature on each of the first image and the second image, wherein comparing the first image and the second image further comprises comparing the additional feature of the first image and the additional feature of the second image.

9. The method of claim 6, wherein comparing a value for each of the plurality of regions or tiles comprises associating a respective value to each of the plurality of regions or tiles based on a mathematical analysis of each region or tile of each of the first and second images.

10. The method of claim 9, wherein the mathematical analysis comprises a Fourier analysis.

11. A duplicate check detection system, comprising:

a memory; and

a processor in communication with the memory, wherein the processor is configured to;

receive a first image corresponding to an image of a first check;

receive a second image corresponding to an image of a second check; and

compare the first image and the second image to determine if the first check is a duplicate of the second check, wherein to compare the first image and the second image the processor is further configured to;

determine a plurality of regions or tiles on each of the first image and the second image around a center of a line of sight determined between coordinates of a first feature and second feature in each of the first and second images; and

compare a value for each of the plurality of regions or tiles in each of the first and second images.

12. The system of claim 11, wherein one of the first point or the second point two-points is associated with a magnetic ink character recognition (MICR) line on each of the first check and the second check.

13. The system of claim 11, wherein the processor is further configured to isolate an additional feature on each of the first image and the second image and compare the additional feature of the first image and the additional feature of the second image.

14. The system of claim 11, wherein to compare a value for each of the plurality of regions or tiles the processor is further configured to associate a respective value to each of the plurality of regions or tiles based on a mathematical analysis of each region or tile of each of the first and second images.

15. The system of claim 14, wherein the mathematical analysis comprises a Fourier analysis.
