I don't have any MATLAB code. You may need to start with an image processing textbook that covers image compression techniques so that you can understand how an arithmetic code might fit into the overall system.

But I m a bit confused in design arithmetic coder and decoder.. I search in internet, but i don't find it.. I find 'design arithmetic coder and decoder for text compression'..But i m confusing to convert it into image compression.. Could u help me to give me source code matlab of Arithmetic coding for image compression? Thank u.. Hi steve..

I love the quirky-bits-of-trivia blogs. I had a good time showing my students the background behind the default image. Every now and then they inadvertently stumble upon it and they think their computer is possessed by some MATLAB ghost. I also like "super user" tips. Like how to publish, or get rid of the gray border using iptsetpref, etc. Sometimes when you've been using MATLAB for a while, you're not aware of the cool new tools until you try and run old code and a warning tells you that function's about to become obsolete. Finally,I think your replies to "I'm about to start my Master's thesis, whill you send me some code on how to do ... " are the essence of diplomacy. Jenelle Steve-

I wud want to work on Progressive Image Transmission invovling EZW technque..in MATLAB.perhaps take one of the methods of SPIHT and incoperate then in EZW and show how it helps in PIT ??!! My Q is would you suggestthis as a good reserach topic, is it too obsolete? I am in the begining of my research and wanted to take ur advise. Also, how shud I start with my MATLAB CODE, I have basic knowledge abt MATLAB but not a whole lot ? I am in a fix...please help..any direction wud be helpful !

I want to know that whether quantitaive measures are better for object identification or Qualitative measure? If qualitative mesuares are important then please list those measures so that I may be able to start my work on qualitative measures of an object. Regards Hi Steve
