A colour-map plugin for the open source, Java based, image processing package, ImageJ

We present an interactive approach to the pseudo-colouring of greyscale images. We implement the technique by computing mappings from a three-dimensional (3D) colour space to a one-dimensional greyscale space (i.e. R to R). To compute our maps, we employ both linear 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. r 2004 Elsevier Ltd. All rights reserved.
