Computational Aesthetics Automatic Mood-Transferring between Color Images

With the digital camera’s invention, cap-turing images has become extremely easy and widespread, while image data has become more robust and easy to manipulate. Among the many possible image-processing op-tions, users have become increasingly interested in changing an image’s tone or mood by altering its colors—such as converting a tree’s leaves from green to yellow to suggest a change of season. Groundbreaking work by Reinhard and colleagues made such a conversion possible and extremely sim-ple.1 In their approach, users provide an input image, along with a reference image to exemplify the desired color conversion. The technique’s algorithm essentially attempts to match the input image’s color sta-tistics with those of the referenc
