Progressive color transfer for images of arbitrary dynamic range

摘要

Image manipulation takes many forms. A powerful approach involves image adjustment by example. To make color edits more intuitive, the intelligent transfer of a user-specified target image's color palette can achieve a multitude of creative effects, provided the user is supplied with a small set of straightforward parameters. We present a novel histogram reshaping technique which allows significantly better control than previous methods and transfers the color palette between images of arbitrary dynamic range. We achieve this by manipulating histograms at different scales, which allows coarse and fine features to be considered separately. We compare our approach to a number of existing color transfer and tonemapping techniques and demonstrate its performance for a wide range of images.
