  From May to July 2004, the central radian of the Galactic Plane was scanned
by the H.E.S.S. (High Energy Stereoscopic System) telescopes at energies above
200 GeV. This survey was performed from -$3^o$ to +$3^o$ in latitude, for a
total of 230 hours, revealing eight new VHE sources at a significance level
greater than 6$\sigma$(standard deviations). We present a multi-resolution
analysis of these sources based on a continuous wavelet transformation (CWT).
Using CO and HI data, we investigate the possible associations of the potential
counterparts proposed in [1], with sites of enhanced interstellar matter
density.
