From: A novel Raman spectroscopic method for detecting traces of blood on an interfering substrate
Results of the Soergel distance calculations in an individual sliding spectral window for various Raman bands. The distance is presented in terms of mean values between the Raman spectra of blood on Al foil and pure blue polyester (a), denim (b), cotton fabric (c), and white polyester (d) substrates. Here, \(i\) is the number of sliding spectral windows.
