Systems and methods for assessing standards for mobile image quality
First Claim
1. A non-transitory computer-readable medium containing instructions which, when executed by a computer, perform a process comprising:
- receiving an image of a document captured by a mobile device;
processing the image to determine a set of image quality assurance (IQA) scores;
performing a computation relating to the set of IQA scores to obtain at least one compound IQA score, wherein the computation includes combining a subset of strongly correlated IQA scores in the set of IQA scores into a compound IQA score, and wherein the subset of strongly correlated IQA scores is associated with a common image defect;
determining if the image meets a predetermined standard of image quality based on the at least one compound IQA score; and
if the image meets the predetermined standard of image quality;
assessing a usability score of the document in the image to ensure that the document belongs to one of a set of supported categories of documents; and
outputting the at least one compound IQA score and the usability score;
otherwise, characterizing the image as unusable.

Abstract
Methods are provided for defining and determining a formal and verifiable mobile document image quality and usability (MDIQU) standard, or Standard for short. The Standard ensures that a mobile image can be used in an appropriate mobile document processing application, for example an application for mobile check deposit. In order to quantify the usability, the Standard establishes 5 quality and usability grades. A mobile image is first tested to determine if the quality is sufficient to obtain content from the image by performing multiple different image quality assessment tests. If the image quality is sufficient, one or more document usability computations are made to determine if the document or content in the image is usable by a particular application. A ranking is then assigned to the image based on the results of the tests which is indicative of the quality and usability of the image.

13. A system for assessing mobile image qualities of a document, comprising:
-
a processor; and a memory coupled to the processor to store instructions for assessing qualities of mobile images of documents; wherein the processor is configured to perform a process of; receiving an image of a document captured by a mobile device; processing the image to determine a set of image quality assurance (IQA); performing a computation relating to the set of IQA scores to obtain at least one compound IQA score, wherein the computation includes combining a subset of strongly correlated IQA scores in the set of IQA scores into a compound IQA score, and wherein the subset of strongly correlated IQA scores is associated with a common image defect; determining if the image meets a predetermined standard of image quality based on the at least one compound IQA score; and if the image meets the predetermined standard of image quality; assessing a usability score of the document in the image to ensure that the document belongs to one of a set of supported categories of documents; and outputting the at least one compound IQA score and the usability score; otherwise, characterizing the image as unusable. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
