this is source code for image compression following jpeg2000 staandard

ImageCompression Toolbox v1.2
-----------------------------
  You have downloaded the source for ImageCompression Toolbox v1.2. To build the executable, just compile 
    1. wavemain.cpp
    2. aricoder.cpp
    3. wavelet.cpp
    4. image.cpp
  into a single executable using any standard C++ compiler. I used Visual Studio v6.0 to build the executable. In case of incompatibilities , write to me and i'll be glad to fix them.
  Support for zerotree encoding is also present, though the implementation is not upto the mark. In fact, encoding using zerotrees require more bits than the normal encoding at present, because the significance map is directly encoded using a 3 symbol arithmetic encoder. Suggestions about this are welcome.
  No commandline options are used. Just go through the functions "main", "xxxx_encode" and "xxxx_decode" in the file "wavemain.cpp" to know the input filename, output filename and the compression ratio.
  Comments are welcome about this source distribution.
