A method for detecting copy restrictive documents is disclosed. At least one photograph (101) is placed on a scanner platen (10) and a low resolution scan is performed (20) to produce a low resolution image. A skew angle and a location of the photograph is determined (30). The photograph is rescanned at a high resolution (40) to produce a high resolution image, the high resolution image is deskewed (45), and the high resolution image is checked (50) for the presence of one or more microdots. Use of the high resolution image is inhibited if microdots are detected (55). In one embodiment, a plurality of photographs are placed on the scanner platen and a portion of each the high resolution images is checked by a software program for the presence of microdots.

Detecting copy restrictive documents

A method for scanning and detecting number and skew angle of photographs (12) and removing edge artifacts is disclosed. A plurality of photograph is placed on a scanner (11). A low resolution scan (34) is conducted of the photographs (12) to produce a plurality of low resolution images. A plurality of polygons is constructed, wherein each polygon contains at least one low resolution image. A number of polygons is determined and compared to the number of photographs. If the number of polygons is less than the number of photographs, the photographs are repositioned to separate overlapped photographs and the low resolution is repeated. A skew angle and location is determined for each of the photographs. A first photograph is selected and the first photograph is scanned at a high resolution to produce a high resolution image. The high resolution image is deskewed and cropped to remove the edge artifacts.
