something like this,

Code:
use File::Compare;
$count = 0;

open (F1, "file1.txt") || die "Could not open file $!";
while (<F1>) {
    @array1=split;
}
close (F1);
open (F2, "file2.txt") || die "Could not open file $!";
while (<F2>) {
    @array2= split;
close (F2);
}
$i=0;
foreach (@array1) {
    if ($array1[$i] ne $array2[$i])
       {$count++; }
        $i=$i+ 1;
}
print "$count \n";

tiffcmp

TIFFCMP(1)						      General Commands Manual							TIFFCMP(1)

NAME

       tiffcmp - compare two TIFF files

SYNOPSIS

       tiffcmp [ options ] file1.tif file2.tif

DESCRIPTION

       Tiffcmp compares the tags and data in two files created according to the Tagged Image File Format, Revision 6.0.  The schemes used for com-
       pressing data in each file are immaterial when data are compared-data are compared on a	scanline-by-scanline  basis  after  decompression.
       Most  directory	tags are checked; notable exceptions are: GrayResponseCurve, ColorResponseCurve, and ColorMap tags.  Data will not be com-
       pared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal.	By default, tiffcmp will terminate if  it  encoun-
       ters any difference.

OPTIONS

       -l     List each byte of image data that differs between the files.

       -t     Ignore any differences in directory tags.

BUGS

       Tags that are not recognized by the library are not compared; they may also generate spurious diagnostics.

       The image data of tiled files is not compared, since the TIFFReadScanline() function is used.  A error will be reported for tiled files.

       The pixel and/or sample number reported in differences may be off in some exotic cases.
