[vtkusers] Help needed using segmented data

[Vidya Raghavan]

Also, to make things clearer... I use mean shift segmentation to segment 
through a set of input 256X256 BMP files 
http://www.cs.northwestern.edu/~vidya/VTK/input_images/.

The segmented data files (http://www.cs.northwestern.edu/~vidya/VTK/data) 
have integer lables for each pixel in the corresponding 256 X 256 images.

I am using these data files when I run region1.tcl

So, I'm not too sure what you mean by Value, and what i need to set it to. 
I'll really appreciate your input.

Thanks again..
