Abstract: An example of a method for time-resolved calculation of a deformation of a body comprises calculating (110) a model of the body during the deformation. The method further comprises calculating (120) a predicted X-ray image for the body for a plurality of time points during the deformation based on the model. The method further comprises obtaining (130) one measured X-ray image of the body each for the time points during the deformation. The method further comprises modifying (140) the model based on the predicted X-ray images and the measured X-ray images.

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.

Abstract: A method and circuit arrangement for electronic retouching of color images is provided. The color signals of at least one color component acquired by pixel-by-pixel and line-by-line, trichromatic scanning of an original are digitized and stored as color values. The pixels of the color values to be retouched in the color image are marked by shifting a correction field that contains at least one dot element over the image region to be retouched, using the marking device of a coordinate acquisition unit. Before the retouch, a correction intensity distribution that achieves the desired retouch effect is declared for the correction field of the marking device. Correction intensity values allocated pixel-by-pixel are identified for the color values of the marked pixels of the color image and the color values to be retouched are modified by the correction intensity values under visual control.
