Abstract:

A technique is investigated for the automatic correction of spacial distortions in digitized television images. This is accomplished by digitizing images of a horizontal and a vertal striped pattern. Correction factors may then be computer so that these known patterns are mapped without distortion onto the image plane. By application of the same factors to arbitrary images, spacial distortion may be corrected. A number of experiments are described in which it is shown that postional errors of as small as 1 of either the horizontal or vertical distance may be corrected. Author
