Lean description on the FEX, no comments in the file, file is a script and not a function, parameter defined by input, a not existing test picture is used and the size must be 500 x 1192.
A RAND matrix is created, its values are overwritten immediately by the number 252, but finally even this value is overwritten by the results. The computation uses 2 loops, although BITAND accepts arrays directly. Without the confusing unneeded lines this is:
  imshow(bitand(imread(FileName), 2^(n-1)));
