Abstract
A unified method for correcting the geometry and color of digital images is presented. The method uses a color chart with a prearranged array of known color patches. Using the true geometry and color of the chart and geometry and color of the image of the chart, transformation functions that describe the geometry and color characteristics of the camera are determined. The transformation functions are then used to correct the geometry and color of obtained images. Experimental results of the proposed method on images acquired under different scene illuminations and camera settings are presented and evaluated
