C-programs for handling color spectra and multispectral images

  • MIV (Multispectral Image Visualization) program

    MIV can display .msi format multispectral images one channel at a time. Any spectra can be selected and viewed in separate window. Some of the most used color co-ordinate systems are also calculated for the spectra.
    Requirements
    C-compiler
    Xview user interface toolkit
    XV image viewer by John Bradley which can be obtained for example from nic.funet.fi.

  • Specshow (Color Spectra Visualization Program)

    Requirements
    C-compiler
    Xview user interface toolkit

  • Speclass (Color Spectra Classification Package)

    Speclass provides the user interface to build learn and test sets from spectral data and to set the parameters of the classifiers included in this package. Some neural and traditional methods are used in classifiers (SOM, Subspace network, ART2, KNN).
    Requirements
    C-compiler
    Xview user interface toolkit

    Matlab macros

    Munsellbook and munsellbookaotf are macros that display pages of The Munsell Book of Color on a Matlab figure window. The RGB colors of the color chips are calculated from measured spectra and the corresponding color spectra can be viewed by pressing mouse button on any color chip.
    Requirements
    Matlab version 4.2a or newer (tested only with this version).
    Munsellbook macro needs Munsell colors matt (spectrofotometer measured) color spectra in matlab format.
    Munsellbook macro needs Munsell colors matt (AOTF measured) color spectra in matlab format.
    Colors macro calculates color coordinates for color spectra [400 nm - 700 nm].
