Abstract

A method of providing an indication of quality of an image of a document comprises the steps of (a) storing apriori data which is representative of a line contained in at least one field associated with the document, (b) receiving image data which is representative of the image of the document, (c) retrieving the stored apriori data based upon a first portion of the document image data, (d) comparing a second portion of the document image data with the retrieved apriori data, (e) providing an indication of quality of the image of the document based upon the comparison of the second portion of the document image data with the retrieved apriori data, and (f) processing the status signal to alert an operator of quality of the image of the document being below a predetermined threshold.

Claims

1. A method of processing a check, the method comprising the steps of:

(a) storing apriori data which is representative of certain features of the check;

(b) receiving image data which is representative of an image of the check;

(c) retrieving the stored apriori data based upon a first portion of the check image data;

(d) comparing a second portion of the check image data with the retrieved apriori data; and

(e) providing a status signal indicative of quality of the image of the check based upon the comparison of the second portion of the check image data with the retrieved apriori data.

2. A method according to claim 1, wherein step (a) includes the step of:

(a-1) storing apriori data which is representative of a line contained in at least one field associated with the check.

3. A method according to claim 1, wherein step (a) includes the step of:

(a-1) storing apriori data which is representative of alphanumeric text contained in at least one field associated with the check.

4. A method according to claim 1, wherein step (a) includes the step of:

(a-1) storing apriori data which is representative of only alphabetic text contained in at least one field associated with the check.

5. A method according to claim 1, wherein step (a) includes the step of:

(a-1) storing apriori data which is representative of only numeric text contained in at least one field associated with the check.

6. A method according to claim 1, further comprising the step of:

(f) processing the status signal to alert an operator of quality of the image of the check being below a predetermined threshold.

7. An apparatus for processing a check, the apparatus comprising:

means for storing apriori data which is representative of certain features of the check;

means for receiving image data which is representative of an image of the check;

means for retrieving the stored apriori data based upon a first portion of the check image data;

means for comparing a second portion of the check image data with the retrieved apriori data; and

means for providing a status signal indicative of quality of the image of the check based upon the comparison of the second portion of the check image data with the retrieved apriori data.

8. An apparatus according to claim 7, wherein the storing means includes means for storing apriori data which is representative of a line contained in at least one field associated with the check.

9. An apparatus according to claim 7, wherein the storing means includes means for storing apriori data which is representative of alphanumeric text contained in at least one field associated with the check.

10. An apparatus according to claim 7, wherein the storing means includes means for storing apriori data which is representative of only alphabetic text contained in at least one field associated with the check.

11. An apparatus according to claim 7, wherein the storing means includes means for storing apriori data which is representative of only numeric text contained in at least one field associated with the check.

12. An apparatus according to claim 7, further comprising means for processing the status signal to alert an operator of quality of the image of the check being below a predetermined threshold.

13. A method of providing an indication of quality of an image of a document, the method comprising the steps of:

(a) storing apriori data which is representative of a line contained in at least one field associated with the document;

(b) receiving image data which is representative of the image of the document;

(c) retrieving the stored apriori data based upon a first portion of the document image data;

(d) comparing a second portion of the document image data with the retrieved apriori data;

(e) providing an indication of quality of the image of the document based upon the comparison of the second portion of the document image data with the retrieved apriori data; and

(f) processing the status signal to alert an operator of quality of the image of the document being below a predetermined threshold.

14. An apparatus for providing an indication of quality of an image of a document, the apparatus comprising:

means for storing apriori data which is representative of alphanumeric text contained in at least one field associated with the document;

means for receiving image data which is representative of the image of the document;

means for retrieving the stored apriori data based upon a first portion of the document image data;

means for comparing a second portion of the document image data with the retrieved apriori data;

means for providing an indication of quality of the image of the document based upon the comparison of the second portion of the document image data with the retrieved apriori data; and

means for processing the status signal to alert an operator of quality of the image of the document being below a predetermined threshold.
