As set forth herein, methods and systems for automated image defect detection. An input image is subjected to skew detection and contaminant detection. Upon detection of skew of and/or contaminants in the image data, correction data, including indicia of the contaminants/skew, correction angles and directions are calculated and displayed on an electronic representation of the document. Automatic correction may then be performed to correct the detected defects, allow the defects to remain, or re-scan the original document to generate new image data without the detected defects.
