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.
