1. A computer implemented method for mobile image capture and remittance processing, where one or more processors are programmed to perform steps comprising: receiving a mobile image of a remittance coupon captured using a mobile device; detecting the remittance coupon within the mobile image of the remittance coupon; generating a document subimage that includes a portion of the mobile image that corresponds to the remittance coupon; geometrically correcting the mobile document image of the remittance coupon to generate a geometrically corrected image; processing the geometrically corrected image to generate a processed image; executing the one or more mobile image quality assurance tests on the processed image to assess the quality of the processed image; and executing one or more remittance processing steps on the processed image if the processed image passes the mobile image quality assurance tests.
