Abstract: The invention relates to an image processing device (1) for finding corresponding first and second regions in two image data sets of an object. In a first image data set a source line and in a second image data set a corresponding target line are determined depending on reference regions detectable in both image data sets. A first region in the first image data set is projected onto the source line, thereby dividing the source line into two source sub-lines and defining a source ratio as the ratio of the length of one of the source sub-lines to the length of the entire source line. A second region in the second image data set is then determined such that a projection of the second region onto the target line leads to a corresponding target ratio which is similar to the source ratio.

Abstract: An apparatus for adjusting images is provided. The apparatus comprises an image decomposing unit for decomposing an input image I into high-pass images HP1, HP2, . . . , HPN and a low-pass image LPN, and an image adjusting values determining unit for determining high-pass image adjusting values ?1, ?2, . . . , ?N for adjusting the high-pass images HP1, HP2, . . . , HPN and a low-pass image adjusting value ?N for adjusting the low-pass image LPN. The apparatus further comprises an image adjusting unit for adjusting the high-pass images HP1, HP2, . . . , HPN using the high-pass image adjusting values ?1, ?2 . . . , ?N and the low-pass image LPN using the low-pass image adjusting value ?N, and an image recomposing unit for recomposing the adjusted high-pass images HP1*, HP2*, . . . , HPN* and the adjusted low-pass image LPN* into an adjusted image A.
