In this paper, we show that the determination of the morphological type could be difficult when we observe galaxies in the rest-frame ultraviolet. This could be crucial as soon as we wish to study galaxies at redshifts beyond z~1 since the visible wavelength range corresponds to the rest-frame ultraviolet. In order to address the problem of performing a morphological analysis on a large number of galaxies as the very large samples that will be secured by GALEX, SLOAN, ASTRO-F in the near- to mid-term and from NGST, ALMA and ELT's later on, we need to define a simple quantitative and automatic method. We propose a quantitative multi-wavelength classification that would take into account the various stellar populations lying in the observed galaxies. This method makes use of multi-wavelength data but such databases are already needed to estimate the distance through photometric redshifts. SpectroMorphology allows to perform an automatic analysis of the nature of galaxies.
