Colour and Multispectral Image
- Adrian Evans
- David Gimenez
The rapidly-increasing availability of multi- and hyper-spectral satellite imagery,
and low-cost colour digital cameras, has resulted in multi-channel image
representations becoming far more prevalent.
This presents many challenges to image processing and analysis as the
extension of many greyscale techniques to more than one channel is not
straightforward. This is particularly
true for nonlinear techniques, for example the median filter and morphological
operations, which are based on pixel ordering.
