Hey,
I am implementing improved AES algorithm on Mathlab. In the begining i want to take input as image , audio , video or text file. But then I need to convert the image in binary format meaning 1's and 0's and same for sound and video file in the binary form....that is series of 1's and 0's. Can you convert video , sound and image file in series of 1's and 0's and store it in an array. Then only I will be able to perform encryption. I don't want the RGB values for the image. Just convert it in binary or analog format. Plz...also tell me to reconvert it back from analog form to image, sound or video....thanx in advance.

fid = fopen('InputFileName');
bits = fread(fid, inf, '*ubit1', 'b');
fclose(fid);
Caution: this will not be able to access resource forks (OS-X) or alternate streams (MS Windows)
