distortion map. We have applied the Formula (11.13) to a TM image obtained
with the method of Ferradans et al. [164]. The HDR source image is taken
from the MPI database [62]. We observe that the LVC distortion has been
reduced, whereas the INV distortion has increased a bit. As we can see in for-
mula (11.13), the preprocessing is only devoted to reduce the LVC and AIC
distortions, and does not take into account the INV distortion. This might
explain why the INV distortion tends to increase. In Table 11.1, we present
results of the preprocessing tested on images of the Fairchild database [66] for
different TMOs, i.e.
