MATLAB: How can I read perform some operation on an image byte by byte??

ImageData = imread('ImageFileName.JPG');
ImageAsBytes = typecast(ImageData(:), 'uint8');
fid = fopen('tempimg.dat', 'w');
fwrite(fid, ImageAsBytes');
fclose(fid);
fid = fopen('tempimg.dat', 'r');
for K = 1 : numel(ImageAsBytes)
  thisbyte = fread(fid, '*uint8', 1);
  .... perform the byte-wise operation here
end
fclose(fid);

Note that this code has been constructed to suit your requirement to "read images byte by byte", which is seldom necessary (or desirable) for steganography purposes.
