Please expand on what you mean. Are you trying to do Optical Character Recognition?

i am trying to convert an image to a text file or an array of strings and it has to be reversible too. This is just a part of my project.

Yes. But you will get better compression if you do Huffman coding on the binary values than on the text representation of the binary values.

An alternative is im2html, which gives a nice visual display: http://www.mathworks.com/matlabcentral/fileexchange/32273-im2html-m
Another alternative is to use sprintf() or fprintf(). It really depends on how you want to use the string.
