ANISOTROPIC EXPANSION
-
(a)
(b)
-
(a) Synthetic circle with radius equal to 50 pixels and
center at the pixel (125,125).
-
(b) Anisotropic expanded images along the vertical direction and for different values of the parameter thr.
Let e1 denote the vertical direction and
e2 the perpendicular one, the
values of the parameters used for the transformation are:
l1=0.001,
l2=100,
it=1000, ndir=32.
The picture in black is the original image; the one in red corresponds to thr=200, whereas the one in blue corresponds to thr=250.

(a)
Anisotropic expanded images along the horizontal direction
e1.
The
values of the parameters used for the transformation are:
l1=0.001,
l2=100,
it=1000, ndir=32.
The picture in black is the original image; the one in red corresponds to thr=200, whereas the one in blue corresponds to thr=250.
-
(b) Anisotropic expanded images along the direction
e1=(√2/2,√2/2).
The
values of the parameters used for the transformation are:
l1=0.001,
l2=100,
it=1000, ndir=32.
The picture in black is the original image; the one in red corresponds to thr=200, whereas the one in blue corresponds to thr=250.
-
Animation for varying thr ranging between 10 and 254. As thr
increases, so the image expands.

ANISOTROPIC CONTRACTION
-
(a)
(b)
-
(a) Synthetic circle with radius equal to 50 pixels and
center at the pixel (125,125).
-
(b) Anisotropic contracted images along the direction e1=(1,0) and for different values of the parameter thr.
The
values of the parameters used for the transformation are:
l1=0.01,
l2=10000,
it=100, ndir=32.
The picture in black is the original image; the one in red corresponds to thr=50, whereas the one in blue corresponds to thr=5.
