Hi..folks..;

Currenlty, I'm handling some stuff on Lossy algo's (for Images).

where can I find image *analysis* tools to check the results,

I mean to see these stuff side by side for the testing image(s).,
like

(a) RMSE,
(b) PSNR,
(c) Histograms,
(d) Spectral analysis,
(e) Handling color spaces,
(f) dithering stuff
etc..etc...,

I hope you people know it better than me;
I don't need to write all those stuff here.

please do share it.

thanks alot for the help :-)

greetings

Netpbm has lots of things to offer, including a PSNR measurement tool
(pnmpsnr), a histogram tool (ppmhist) and other nifties. For color space
conversions, the tiff toolchain offers a tool to apply an ICC color
profile to a given image (tifficc) that can be used. netpbm also
includes tools for dithering (ppmdither). You can get the sources, so
modify all that to your needs.

So long,
Thomas

I have found the "MSU Video Quality Measurement Tool" helpful for
evaluating both image and video codecs. Refer to
http://compression.ru/video/quality_...t_tool_en.html
as a starting point, there are plenty of links to related tools and
topics.

Take care,
Dennis

thnx Thomas for the update, you are quick & very fast :_)


therefore it means that,

there exists no pre-coded C/C++ or anyother lang
libraries to handle these stuff.

I'm afraid, I'm not wrong;

so long

why can't we Usenet community { compressors, imageanalysts & DSP guys)
do this stuff for ourselves.

Any proposals or ideas..?

Just to make sure you got this right: Netpbm *allows you* to get the
sources, but you surely find binary distributions. Most linux
distributions I know cover it. Cygwin most likely includes it as well.
So no, you don't have to recompile. But you can if you wish.

So long,
Thomas

WHAT DO MUSLIMS BELIEVE?
I send you today a good article. It could be new and adds to your
knowledge.


WHAT DO MUSLIMS BELIEVE?


Muslims believe in One Unique, Incomparable God; in the Angels created
by Him; in the prophets through whom His revelations were brought to
mankind; in the Day of Judgement and individual accountability for
actions; in God’s complete authority over human destiny and in life
after death. Muslims believe in a chain of prophets starting with Adam
and including Noah, Abraham, Ishmael, Isaac, Jacob, Joseph, Job,
Moses, Aaron, David, Solomon, Elias, Jonah, John the Baptist, and
Jesus, peace be upon them. But God’s final message to man, a
reconfirmation of the eternal message and a summing-up of all that has
gone before was revealed to the Prophet Muhammad through Gabriel

Nobody gives a shit, sand-nigger. Go back to your tribe.

Your question is a bit strange. The best image analysis-tool you can
find is Mathlab or Mathematica.
You say you don't want to write those? Do you program? In which
language? There are even libraries for LISP out there.
In the end almost no library will fit your bill (it's in your
language, it is like you want it to be, it's all done). I programmed
my own 60MB library because of that (I collect source, that's why it's
so big ;^), too much cool algorithms to rewrite from old weird tools),
and it will definitly not fit into other people programming paradigma.

I can give you the tool-chain I use for CDB, but for everything else
(laying hand on it) you'd need to know C++ in&out.

Nimo,

I'm not sure if it would provide any of the functions you're looking
for, but check out GNU octave and the available image processing
library:

http://octave.sourceforge.net/doc/image.html
