Spectral Analysis for Polychromatic Light Sources and Drinking Water Samples By Using Blind Quality Assessment


Abstract--- An attempt to quantify the spectral response of the polychromatic light sources and drinkingwater samples has been presented in this research. This had been executed by an objective methods of imagequality assessment, in which the criteria of error visibility (differences) between images had been appliedtheoretically and practically. The theoretical part had been presented here by image quality assessmentwhich gave results match with that of the practical part resulted by lab investigation. Otherwise and in spiteof its differences in physical and chemical properties, samples of drinking water with their existencepercentage didn't make any variation in the spectrum of polychromatic light sources and hence the spectrumof the light sources remains unchanged.
