Examples
M = [0:10;0:10]; I = mat2gray(M); |  |  |
Convert matrix to grayscale image
G = mat2gray(M) G = mat2gray(M, [mmin, mmax])
[mmin, mmax]
is the values in
M
that correspond to
0.0
and
1.0
in
G
. The elements in
M
which is lower than
mmin
will be converted to
0.0
, and greater than
mmax
will be converted to
1.0
.mat2gray(M,[mmin, mmax]) converts the matrix
M to the double precision image. The output matrix
contains values in the range [0.0, 1.0].
mmin and mmax are the values in
M that correspond to 0.0 and 1.0 in the output
image.
When [mmin, mmax] is not specified,
minimum and maximum of
M are the values in M that
correspond to 0.0 and 1.0 in the output image.
M = [0:10;0:10]; I = mat2gray(M); | | |
