I need a matlab code for normalizing this chart between 0 and 255

I projected a colored sinusoidal fringe patterns with amplitude 255 (0-255), then I captured image of the pattern with a camera. I found that each fringe has different amplitude as shoown in the figure. I need a matlab code for nomalizing these ampliudes to return to its original values

A first approximation could be something like this:
%generate some data
t=1:200;
data=80+70*sin(t/4)+rand(size(t))*5;
data=data-min(data(:));
data=data*255/max(data(:));
A better solution is probably to fit a function to your data and model the minimum and maximum values.
