limbo - fast 2D/3D fractal image compression


    Limbo is a  very  fast  fractal  image  object  encoder.  It
    encodes  an  input  image  by approximating it with a set of
    affine contractive mappings - the fractal code.

    The current version can briefly  be  summarized  with  these
    features:

    Current features:

      o  Complete  very  fast encoding of images or sequences of
         images.

      o  Full  storing,  retrieving  and decoding of the fractal
         code in a general interchange format.

      o  A  special n-dimensional feature space search technique
         to reduce the encoding time.

      o  Quadtree encoding using n-levels.

      o  Decode  expansion  at  any level (i.e.  2, 4, 8...times
         original size).


    Image input and output is in the PPM (color)  or  PGM  (grey
    level)  format.

    The output from the encoder is in a  special
    'limbo' fractal format (*.lmb).
