[vtkusers] Time Optimization

[Mallya, Yogish (CORP, GEITC)]

Hi All,
	 In my application, I have a loop  that enables me to extract a
slice from the data set(one image at a time) and the extracted image is
passed through the connected component filter. I want to  limit the
processing to set of regions obtained from the connected component filter
instead of whole image for remaining filters inside the loop( time
optimization ) . I can access the  region information( rectangle bounding
box) from the connected component. Based on the bounding box parameter, i.e
Xmin,Xmax,Ymin and Ymax, I am setting the UpdateExtent for subsequent
filters. In this approach there two problem
1. I get the Error message "Update extent does not lie within whole extent"
2. process whole image( not desired ) + process regions (desired)

Question is "How to limit the processing only to bounding box regions
instead of processing the whole image ?"

Any Help appreciated,
