Abstract
We present an interactive approachto thepseudo-colouring of greyscale images. We implement the technique by
computing mappings from a three-dimensional (3D) colour space to a one-dimensional greyscale space (. R3 to R). To
compute our maps, we employ bothlinear and nonlinear interpolation in 3D colour space. We validate our work by
applying our maps to greyscale images resulting in significant image enhancement. Applications include space imagery,
geological topographies, medical scans and many more. Our tool is coded as a Java plug-in for the open source image
processing package, ImageJ.
