Crome

A suite of programs which compute correlation coefficients between pairs of wavelengths from an NIR data set and display them as a colour plot. See http://www.spectroscopyeurope.com/columns/tony-davies-column for more details.

Generally, the spectral dataset include too many wavelengths which could contribute the collinearity, redundancy and noise to models. The correlation coefficients between pairs of wavelengths derived from spectral reflectance can enhance the relationship between spectral features and object, and also could eliminate the irrelevant wavelengths.
