Abstract
A significant fraction of galaxies in the Local Universe classified as unbarred in the RC3 turn out to be barred in optical and NIR wavelengths. In the Local Group the Milky Way and M31 have shown to be barred as well, this also could be the case of M33. In this paper we present the results of the Ellipse fitting and bidimensional Fourier Analysis, on the R and I bands, deprojected and non-deprojected, images of M33 obtained from DSS2 and Spitzer-IRAC.
