Abstract
Techniques and systems to transfer color robustly between images are described. In an embodiment, a technique for transferring color includes separating color information of a registered source image into a one dimensional luminosity channel and multi-dimensional chromatic channels. The technique further includes building a voting table, where each table cell is indexed by the chromatic coordinates from the source image and from the destination image. The table is built by adding to a count stored in a table cell indexed by the chromatic coordinates of the source pixel and the chromatic coordinates of its related destination pixel for each occurrence of such a pairing. The voting table values are used to identify a transfer color, and to adjust the colors of the source image to the colors of the destination image. Other embodiments are described and claimed.
