Abstract
An image quality assurance method for identifying image defects in a plurality of imaged documents, where each imaged document includes at least one image rendition. The image renditions are analyzed to provide selected image metrics, the latter of which are compared against preselected image quality metric threshold values. An image quality flag is generated for any image rendition if at least one of the selected image metrics for that image rendition does not successfully compare against the preselected image quality metric threshold values. A record entry is created in an image quality flag file for those documents having at least one flagged image rendition, the record entry including information about the selected image metrics of the at least one flagged image rendition for that imaged document. Image defects in a plurality of imaged documents can be identified by examining the record entries in the image quality flag file.
