Abstract
A method for integration of a source object into a base image. The method comprises the steps of identifying similar border pixels, calculating characteristic values of the similar border pixels in the source object and the base image, creating a tonal map using the characteristic values, segmentation filtering the source object and the overlapped area into regions, identifying similar regions in the source object, each of which, in the characteristic values, has a difference smaller than a second threshold from the similar border pixels in the source object and smaller than a third threshold from one region in the overlapped area having an average difference smaller than a fourth threshold from the similar border pixels in the overlapped area, and applying the tonal map to the similar regions.
