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 capture device can capture images. A mobile device can receive information associated with one or more image quality assurance (IQA) criteria; evaluating the images to select an image satisfying an image quality criteria based on the received information; and in response to the image satisfying the image quality score, sending the selected image to determine a set of image quality assurance (IQA) scores. ## Claims ### Claim 1 A non-transitory computer-readable medium comprising instructions which, when executed by a processor, cause the processor to: capture images using a mobile image capture device; receive information associated with one or more image quality assurance (IQA) criteria; evaluate the images to select an image satisfying an image quality criteria based on the received information; and in response to the image satisfying the image quality score, send the selected image to determine a set of image quality assurance (IQA) scores. ### Claim 2 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein to satisfy an image quality criteria, content is at least extractable from the selected image based on the received information. ### Claim 3 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the processor is further to determine a false selection in response to an IQA score associated with the selected image of the set of images not satisfying the predetermined standard of image quality. ### Claim 4 (depends on 3) The non-transitory computer-readable medium of claim 3, wherein the processor is further to calculate a false selection rate of the images. ### Claim 5 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein in response to the images failing to satisfy the image quality criteria; rejecting the images. ### Claim 6 (depends on 1) The non-transitory computer-readable medium of claim 1, further comprising: in response to sending the selected image, receive an indication if the selected image is not accepted as sufficient to proceed; and evaluate the images to select another image of satisfying the image quality criteria. ### Claim 7 (depends on 1) The non-transitory computer-readable medium of claim 1, further comprising: in response to sending the selected image, receive an indication if the selected image is accepted as sufficient to proceed. ### Claim 8 (depends on 7) The non-transitory computer-readable medium of claim 7, wherein the selected image is sufficient to proceed based on at least one compound IQA score associated with the selected image of the images satisfying a predetermined standard of image quality. ### Claim 9 (depends on 8) The non-transitory computer-readable medium of claim 8, wherein the set of image quality assurance (IQA) scores comprises: a computation relating to a set of image quality assurance (IQA) scores for the selected image to obtain at least one compound IQA score, and wherein the set of IQA scores is based on at least 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. ### Claim 10 (depends on 9) The non-transitory computer-readable medium of claim 9, wherein the set of IQA scores includes one or more of: an out-of-focus (OOF) score, a shadow score, a small-image-size score, a view-skew score, a plain-skew score, a warpage score, a low-internal-contrast score, a reflection score, a cut-corners score, a cut-sides score, a busy-background score, and a low-external-contrast score. ### Claim 11 A system for assessing mobile image qualities of a document, comprising: an image capture device; a processor; and a memory coupled to the processor to store instructions for assessing qualities of mobile images of documents; wherein the processor is coupled to the image capture device is configured to: capture images using a mobile image capture device; receive information associated with one or more image quality assurance (IQA) criteria; evaluate the images to select an image satisfying an image quality criteria based on the received information; and in response to the image satisfying the image quality score, send the selected image to determine a set of image quality assurance (IQA) scores. ### Claim 12 (depends on 11) The system of claim 11, wherein to satisfy an image quality criteria, content is at least extractable from the selected image based on the received information. ### Claim 13 (depends on 11) The system of claim 11, wherein the processor is further to determine a false selection in response to an IQA score associated with the selected image of the images not satisfying the predetermined standard of image quality. ### Claim 14 (depends on 13) The system of claim 13, wherein the processor is further to calculate a false selection rate of the images. ### Claim 16 (depends on 11) The system of claim 11, wherein in response to the images failing to satisfy the image quality criteria; rejecting the images. ### Claim 17 (depends on 11) The system of claim 11, further comprising: in response to sending the selected image, receive an indication if the selected image is not accepted as sufficient to proceed; and evaluate the images to select another image of satisfying the image quality criteria. ### Claim 18 (depends on 17) The system of claim 17, wherein the selected image is sufficient to proceed based on at least one compound IQA score associated with the selected image of the images satisfying a predetermined standard of image quality. ### Claim 19 A method comprising: capturing images using a mobile image capture device; receiving information associated with one or more image quality assurance (IQA) criteria; evaluating the images to select an image satisfying an image quality criteria based on the received information; and in response to the image satisfying the image quality score, sending the selected image to determine a set of image quality assurance (IQA) scores. ### Claim 20 (depends on 19) The method of claim 19, wherein to satisfy an image quality criteria, content is at least extractable from the selected image based on the received information.
