CORRECTING THE GEOMETRY AND COLOR OF DIGITAL IMAGES

A unified method for correcting the geometry and color of digital imag es is presented. The method uses a color chart with a prearranged arra y of known color patches. Using the true geometry and color of the cha rt and geometry and color of the image of the chart, transformation fu nctions that describe the geometry and color characteristics of the ca mera are determined. The transformation functions are then used to cor rect the geometry and color of obtained images. Experimental results o f the proposed method on images acquired under different scene illumin ations and camera settings are presented and evaluated.
