This directory contains the sources of the C-implementation of the IMA
skeleton of a 3D data set as described in the paper: 

W. H. Hesselink, J. B. T. M. Roerdink: Euclidean skeletons of digital image
and volume data in linear time by integer medial axis transform. IEEE
Trans. Pattern Anal. Machine Intell. 30 (2008), pp. 2204--2217.

The main program for computing the IMA is: ima3d

Typical usage:  

	ima3d INPUTFILE <-g gamma>

Here INPUTFILE is the name of the binary 3D input data in SFF format.
The input file is expected in the directory data.
An example dataset is provided: angio.sff

gamma is the value of the pruning parameter (default: gamma=1).

For help, type: ima3d --help

Auxiliary programs:

- makemip: compute a Maximum Intensity Projection of a 3D dataset in SFF
  	   format

- sff_to_fld: convert data set in SFF format to AVS field format 

- fld_to_sff: convert data set in AVS field format to SFF format
