To whom it may concern:
This directory contains software to segment multispectral
or monochrome image data. It uses the SMAP segmentation algorithm
to improve segmentation quality by employing spacial context.

*************************************************************
WARNING FOR PC USERS:
PC's seem to change the name smap-1.5.tar.Z to smap-1.5.tar.tar.
This confuses programs like winzip that decompress the file.
The solution is to change the extensions ".tar.tar" back
to ".tar.Z". An alternative solution is to download the
uncompressed file "smap-1.5.tar".

smap-1.6.1.zip
smap-1.6.1.tar
smap-1.6.1.tar.Z
	Is a compressed and tar'ed directory containing the C_code
	and data to:

	@ Estimate class model parameters using an unsupervised 
	  clustering algorithm.

	@ Segment a multispectral (or monochrome) images using the 
	  SMAP multiscale segmentation algorithm documented in:
             C. Bouman, M. Shapiro
             "A Multiscale Model for Bayesian Image Segmentation"
             IEEE Trans. on Image Processing
             vol. 3, no. 2, pp 162-177, March 1994.

These algorithms are also available in the public domain
Geographic Information System, GRASS. In grass they
are known as i.msigset and i.smap .


images_94_paper.zip
images_94_paper.tar
images_94_paper.tar.Z
	This is a compressed and tarred directory containing
	the test images used in the paper:
             C. Bouman, M. Shapiro
             "A Multiscale Model for Bayesian Image Segmentation"
             IEEE Trans. on Image Processing
             vol. 3, no. 2, pp 162-177, March 1994.

	This data is useful because it has been used by a number
	of authors to compare algorithms.


images_91_paper.zip
images_91_paper.tar
images_91_paper.tar.Z
	This is a compressed and tarred directory containing
	the test images used in the paper:
             C. Bouman, B. Lui, 
             "Multiresolution Segmentation of Textured Images,"
             IEEE Trans. PAMI
             vol. 13, no. 2, pp 99-113, Feb. 1991.
