 Contents
------------------------------------------------------------------------

The package comprises these functions

- ./datasets		: contains test data and loading scripts.
- ./functions		: various sub-routines written by authors.
- ./library			: external library. Please see requirements section.
- ./results			: pre-computed data and resultant segmentation 
					  will be saved here.
- load_*.m			: pre-computes { image database / feature map
					  intra- and inter-image graph / node dissimilarity}.
					  This takes most of processing time.
- load_settings.m	: provides algorithm parameters used in each scripts.					  
- MRW_IS_CS.m		: performs `MRW-IS' and `MRW-CS'
- RUNME.m			: demo script


------------------------------------------------------------------------
 Installation
------------------------------------------------------------------------

- You first download test data and unzip it to './datasets.' For
  example, iCoseg dataset (CMU_Cornell_iCoseg_dataset.zip) can be
  downloaded from http://chenlab.ece.cornell.edu/projects/touch-coseg/
  
- You also need external algorithms. Please see next section.

- Run RUNME.m
