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.

[satya]

and how to convert str to image further?

[Image Analyst]

uint8() and str2double().

[Eman Gomaa]

can i use it in huffman coding and decoding

[Walter Roberson]

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.
