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
nimo

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

Refer to http://compression.ru/video/quality_measure/video_measurement_tool_en.html as a starting point, there are plenty of links to related tools and topics. Take care, Dennis

I'm afraid, I'm not wrong; so long nimo Thomas check your private e-mail _____ why can't we Usenet community { compressors, imageanalysts & DSP guys) do this stuff for ourselves. Any proposals or ideas..?

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

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 ������������ For more information about Islam http://english.islamway.com/ http://www.islamhouse.com/ http://www.discoverislam.com/ http://www.islambasics.com/index.php http://english.islamway.com/ http://www.islamtoday.net/english/ http://www.islamweb.net/ver2/MainPage/indexe.php http://www.sultan.org/ Contact Us At Imanway.group@gmail.com

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. Ciao Niels
