Abstract
In a method for automatic removal of image errors in digital image data, for example which have arisen due to scratches, hairs, etc., a contour mask is generated with a contour filter and a color mask is additionally generated that covers the image areas having the typical color of an image error. By operating the contour mask and the color mask, an error mask arises that is also automatically corrected and is manually edited as warranted. The remaining contours of the error mask are vectorized. An automatic bleeding retouch is then implemented along the vectorized contours.
