How to convert an image to a plain text & inverse ?

Hello

I have an image 128x128 and i want to convert it into a plain text

& how to reconvert that text into an image again ?

What class does this image have? UINT8? If so, why do you assume, that "plain text" means something else?

There are countless ways to convert an image to text. A literal interpretation would be something like:

% convert to text file
A = imread('cameraman.tif');
fid = fopen('textpict.txt','w');
fprintf(fid,'%s',char(A(:)));
fclose(fid);

% read text file and rectify geometry
B = fileread('textpict.txt');
B = uint8(reshape(B,256,[]));

% compare 
immse(A,B)

Or you could write a delimited text file full of numbers...

Or you could come up with some encoding scheme...

What if it's a color image?
