Hello.

An example data file is here:

Simply renaming it to combY.jpg and opening it with irfanview will
display the first image in the package.

I am on linux and non-of the usual tool did work for me :

Kind regards and thanks in advance for any suggestions, Niek

Here is what I used:

$ jpeginfo test.jpg

The jpeg marker is at 0x6c AFAIK

2cts

I have another example of a package that probably consists of more
jpgs here:

http://www.ibbu.nl/~nsprakel/combK

$ strings combY | grep JFIF |  wc
      2       2      10

$ strings combK | grep JFIF |  wc
     10      10      50

Use an hex editor and look for JFIF (pretty easy). You>ll see there is
a small header before each jpeg. So I would guess layout is:

main header (12 bytes):
01 00 00 0A  00 02 62 96  03 0F 04 15

for each jpeg:
  108 - 12 = 96 bytes header per jpeg
  then the first jpeg marker: ffd8

inspect the main header and you might find 2 or 10 encoded for the
number of files. and maybe you have the jpeg length encoded in the
'header per jpeg'.

good luck
[/quote]
Thx a lot for your help. I think with a hex editor and a little
programming in prolog, I should be able
to obtain the individual jpgs.

Since you seem to new here, a couple of facts (and I mean facts and not
"conjectures"):

Jules is around here for more then ten years, claiming every time he>s
showing up having invented the ultimate compression program, and failed
every single time to provide any evidence for its existence, usually
with rather goofy arguments. Most of his inventions break elementary
rules of logic, such as that there is no invertible N to M mapping for N
[quote]M, so only very little training will allow you to prove him wrong. I
throw $100 into the pot for betting he>s unable to give a demonstration[/quote]
of his invention this time yet again. Demonstration again by the very
same rules people posted here over again:
a) Jules makes binaries for his compressor available,
b) I (or someone else) downloads that executable,
c) I (or someone) creates a test-corpus of files,
d) Jules compresses the files
e) Jules makes the files available for download,
f) I (or someone else) expands the files with the executable from the
step b) above,
g) if all expanded files compare equal to the original, and all
compressed files are smaller than the input files, Jules wins, otherwise
I (or someone else) wins.

From the same argument also follows that you cannot compress any file
to 77 bits, we>re making only a bit fun of you here - sorry.

As a survival kit for this group, make sure you understand the "counting

Now you got the length of your file 26-1=25units.

you would get a unique graph on Cartesian co-ordinate
geometry[Euclid>s]

A gentle reminder-- earlier you signed with:
Rejector of Euclidean Geometry,
Admirer of Rene Descartes.

So, you must have written the ``coordinate geometry(Euclid>s)" above by mistake.

use any of these rules to find out area

(a)Simpsom>s 1/3 rule
(b)Simpson>s 3/8 rule
(c)Trapezoidal rule.
(d)Booles rule.

From my implementation of such algorithms I found different variations of Gauss Quadrature algorithm the most efficient(speedy And accurate).

Now in your hand you have area and length of your file,

Area=l*b.

therefore the 'parts' of the 'breadth' is our given string.

So, you mean you will store only A and l and recover the points during decompression? I understood this only-- and if you actually mean this I guess a simple attempt to achieve this will tell you the problems that lies therein.

Eg:-1001000100011111011110111

1  0  0  1   0   0   0  1   0    0     0  1    1    14
1  2  3   4  5   6   7   8  9    10  11  12  13

1   1    1     0    1     1    1     1     0     1     1      1
15  16  17   18   19   20   21   22  23    24   25    26

Now you got the length of your file 26-1=25units.

you would get a unique graph on Cartesian co-ordinate
geometry[Euclid>s]

use any of these rules to find out area

(a)Simpsom>s 1/3 rule
(b)Simpson>s 3/8 rule
(c)Trapezoidal rule.
(d)Booles rule.

Now in your hand you have area and length of your file,

Area=l*b.

therefore the 'parts' of the 'breadth' is our given string.

Thanks.

Hi Nimo,

last time I do play with something like this, I cannot
make it work, may be just share it if
you can come up with something.

as we know a so call packed random file has almost equal number of
byte type. eg. if there is 100 Character 45,
it will be more or less number of character 20 etc, to be simpler, 50%
0 and 50% 1

so if I know there is almost same amount of the 256 character, I can
really do a combinatoric extraction from it.
For example (using 00,01,10,11)

If there is a random string. 00 01 00 10 10 10 11 11 10 10 00 11 00 11
01 01 01 01 00 11
1 2 1 3 3 3 4
4 3 3 1 4 1 4 2 2 2 2 1 4

as you know Combinatorics 4x3x2x1 = 24,
We can extract the string like this.

00 01 00 10 10 10 11 11 10 10
00 11 00 11 01 01 01 01 00 11
1 2 1 3 3 3 4
4 3 3 1 4 1 4 2 2 2 2 1 4

Extra Info derived (Eg)
First code 1 2 3 4
Second Code 1 3
4 2 (3
must after the first code 3 so as 4)
Third Code
3 1 4
2 (within 3 and 1, there is no 4 and 2
anymore)
Fourth Code
3 1 2 4 (this 2
must after the 3th code 2),
Fifth
Code
3 4 2 1 (this 2 must
after the 4th code 2)


For the 5 codes combinations, you need 24^5 which is around 23 bit to
store it. as the original string is 40 bit,
there is still left 17 bit to store the length. The length combination
is quite complicated, but it is not without
certain pattern within the 23 bit information. as the combination of
the 24 type of code rotation tells the
order information as well eg, first code of every combination state
the first redundant code type.
By utilize the derived information, we might had some hope.... (joke)

Just my two cents.
