1. A computer-implemented method for comparing images for content consistency, the method comprising:
receiving a first image including a first document and a second image including a second document;
performing a visual classification analysis on the first image and the second image, the visual classification analysis generating an overlap of the first image with the second image;
determining whether a region of the overlap is indicative of a content inconsistency; and
as a result of the region of the overlap being indicative of the content inconsistency, performing a character recognition analysis on a first area of the first image and a second area of the second image corresponding to the region of the overlap to verify the content inconsistency.
