Abstract
A spectral image processing algorithm which converts colorchecker spectral image into RGB color space, using as input data the spectrums of a set of amber filters, is presented. The amber filters have gradual transmittance allowing the algorithm to generate images which have gradual amber color hue. Reflective color measurements of a specific area of the image can be carried out and analyzed, making possible to identify the type of filter which was used to color that area by using the white color as reference. The simulations are made using an algorithm which converts the spectral image into LAB color space, RGB color space and finally reconstruct the spectrums of the initial amber filters.
