Method and apparatus for color transfer between images

摘要

A method and an arrangement for color transfer between images for compensating color differences between at least two images as a first and a second image represented by pixel data are recommended, wherein for corresponding feature points of the images a color map and a geometric map are calculated for compensating a first image by applying said geometric map and said color map to the first image resulting in a compensated first image for detecting regions where a compensation fails by comparing the compensated first image with the second image to perform a color transfer excluding image regions where the compensation failed. The method can be performed on the fly and is applicable for equalizing color differences between images different in geometry and color which is e.g. helpful to reduce the resulting bitrate for transferring data, data compression or precise disparity estimation in 3D applications as well as for an improved color coherence of textures of 3D objects.
