/*
ATENTION: The format of the input file for using with this program is:
number_of_patterns minterval_domain
d_dim1 d_dim2 ... d_dimn
percentage minterval_pattern
...
Example:
1000 [1:800,1:600]
10 10
0.40 [10:600,30:300]
0.60 [70:500,400:500]
Creates a file with 1000 patterns on a 800x600 domain.
The pixels are generated having borders with a maximum variation of
10 pixels from the specified interest zones. And 2 interest zones
are specified, one for 40% of the patterns, another for 60%.
