Abstract
The goal of this paper is to present a spectral image processing algorithm that is capable to convert a spectral image into a sRGB image and then to determine the spectral characteristics of the colors which contribute to the image of a colored object. The reflective color measurements of a specific area of the image can be carried out and analyzed, making possible to identify the dyes in that area by using white color as reference. The colored images are generated taking as input data the optical spectra of Rhodamine 6G thin films deposited from solutions with different concentrations. Optical spectroscopic and spectral image processing algorithm investigations of the colored thin films present a gradual attenuation of the light in the visible range, revealing significant filtering properties.
