Although greyscale intensity values are primarily used in image data visualization oftentimes, due to the requirements of aesthetics (whether they be self-imposed or collaborator-suggested), mapping the greyscale image to a user-defined colormap is desired. In this paper, we propose a framework for inclusion in the ITK library for converting intensity-valued images to user-defined RGB colormap images. We also include several colormaps that can be readily applied for visualization of images in such programs as ITK-SNAP or can be used as examples for creating new colormaps.
