[Insight-users] 2. Selective FloodFilling and Region Growing

[Miller, James V (Research)]

Do we need separate iterator classes to perform these operations? It looks
like what you are trying to accomplish is the original intent of the 
ImageFunctionConditionalIterators (walk one image based on information 
from (possible a different) image). The difference here is that you may 
want to walk an output image based on information from two image (an 
input image and a mask image).

Can we use an ImageFunction that operates on two images (one being 
a mask) instead? 

This will keep the iterator code consistent.

> Hello Luis,

> Here is my version of the FloodFilling filters. They are modified to
perform selective growing by accepting 
two new Inputs:

>     2. threshold

where pixels in the input image will not be considered if the corresponding
pixels in the "mask image" are 
less than "threshold".

In my application, I modified the ConnectedThresholdImageFilter and
ConfidenceConnectedImageFilter to use 
this version.

filters are now templated also over the

functions
> 
   SetMaskImage( maskImage ) 
>    SetThreshold( threshold )
> 
are used to define the new inputs. 

note: if any (or both) of these inputs is not given, the filters will behave
just like the normal ones.
