This article proposes the use of special marks or symbols on scanned images to make computer processing faster and easier and a color-sensitive scanning device for facilitating the recognition of added marks. The proposed marks are especially suitable for detection and recognition by image-processing programs. These marks can be put on a picture in ways that are comfortable for draftsmen, that are minor extensions of current graphic techniques, or that are inexpensive additions to current computer-generated pictures. The proposed marks or symbols are here grouped according to function. The use of a particular color for the special marks could facilitate their recognition. The shown device uses a green laser 1 and a red laser 2 as light sources.
