Hi guys, may I ask how do I implement a transformation function on an image?
Maybe it's a function like this: T : , where x is any number and k is the grey scale level, used on a 256 level grey image.
function [Iout,m,mu2,mu3] = enh(Iin,a,b) %take in values of a and b
I = Iin;
for i = 1:254
I(I == i) = a*(i+b);
end
Iout = I;
...
Here is my recent attempt, where I tried to loop the matrix through (Iin) and writes in new values with each loop.
However the code did not work. All the values became 255 after passing through enh
May I know how do you do this?

If r is the input image, and k is your scalar number, you can create output image s simply by doing this:
s = k * r;
