Abstract
A first aspect of the present invention is a process for masking a scanning artifact within image data representing a document. The process includes generating pixel classification tags for the image data; identifying a window within the image data associated with a scanning artifact using the pixel classification tags; analyzing the image data to derive a replacement video value; and replacing image data associated with a scanning artifact with the replacement video value.
