Choice of an estimation area
The results depend on the image on which we estimate the parameters.
Therefore they depend on the area from which this image is extracted :
Values of
estimated on 64x64 areas extracted from "Nîmes", with
=2
Estimation on the entire image gives
=
0.19
.
On this original image are represented :
in red,
insufficiently regularized areas (too much noise)
in blue,
oversmoothed areas (not enough details)
If we only use
one couple
for the entire image,
we must choose
a representative area of
this image.
