Abstract

A configurable image quality analysis system for use at a point of presentment includes an input receptive of an item image of a physical item at least partially embodying a financial transaction. An image quality module is adapted to perform a plurality of image quality tests on the item image according to a plurality of configurable test parameters. An edit module is adapted to perform at least one edit on images of unacceptable quality as defined by the image quality module according to a plurality of configurable edit parameters. An output is adapted to report results of the tests of the image quality module and an edited image from the edit module.

Claims

1. A configurable image quality analysis system for use at a point of presentment, comprising:

an input receptive of an image of a physical item at least partially embodying a financial transaction;

an image quality module adapted to perform a plurality of image quality tests on the image according to a plurality of configurable test parameters to identify a poor quality image;

an edit module adapted to perform at least one edit on the poor quality image to generate an edited image; and

an output adapted to report at least one of the edited images and a report of results from the plurality of quality tests of the image quality module and the edit module.

2. The system of claim 1, wherein the edited image is stored in a transaction datastore.

3. The system of claim 1, wherein the report is stored in a transaction datastore.

4. The system of claim 1, further comprising a workflow module adapted to sequence the plurality of image quality tests.

5. The system of claim 4, wherein the workflow module is further adapted to configure an image display parameter.

6. The system of claim 1, further comprising an image usability module adapted to configure and extract a test field from the image, and wherein the usability test fields are used to determine an acceptance state based upon the presence of the test field on the image.

7. The system of claim 6, further comprising a data and image integrity module adapted to determine a validation state based upon a comparison of visual data extracted from the image with a validation characteristic.

8. The system of claim 7, wherein the data and image integrity module is further adapted to retrieve the validation characteristics from a datastore.

9. The system of claim 1, wherein the image quality module performs at least one, image test function selected from the group consisting of a partial image test, excessive skew test, piggyback image test, too light test, too dark test, streaks test, bands test, exceeds minimum size test and maximum size test.

10. The system of claim 1, wherein the edit module performs at least one image edit function selected from the group consisting of border detection, filtering, cropping, rotation, annotation, framing, scaling, and image conversion.

17. The method of claim 10, further comprising determining validation state based on a comparison of visual data extracted from the item image with a validation characteristic.

18. The method of claim 17 wherein the validation characteristic is retrieved from a datastore.

11. A method of performing image quality analysis on an item of a financial transaction, comprising:

retrieving a job profile from a datastore, wherein the job profile includes a set of document identifiers and a set of image quality test parameters;

generating an image record of a physical item;

reading an item image according to the set of document identifiers;

performing an image quality test based on the set of quality test parameters of the job profile to determine an image quality state;

editing the flawed image based on the image quality state and the set of edit parameters of the job profile to create a corrected image record; and

posting the image quality test results and the corrected image record to a screen for viewing.

12. The method of claim 11, further comprising configuring a workflow parameter to sequence execution of the at least one imagine quality test.

13. The method of claim 12, further comprising configuring work flow parameters to display the image quality test results and the corrected image record.

14. The method of claim 11, further comprising posting the image quality test results and the corrected image record to a transaction datastore.

15. The method of claim 11, further comprising determining an acceptance state based the presence of a usability test field in the image record.

16. The method of claim 15 wherein the acceptance state is retrieved from a datastore.

19. The method of claim 11, wherein performing at least one image quality test includes at least one test selected from the group consisting of partial image test, excessive skew test, piggyback image test, too light test, too dark test, streaks test, bands test, exceeds minimum size test and maximum size test.

20. The method of claim 11, editing the flared image includes at least one editing function selected from the group consisting of deskewing, adding annotation, framing, scaling, and converting the flawed image.
