[Insight-users] Pixel Extraction

[Dan Mueller]

Hi Raghu,

If your ROI is defined as a cubiodal region aligned with the image
data (ie. represented as a starting index with a size) then you should
be able to use an image region iterator to step through the pixel
data. Please look at the following examples:
    Examples/Iterators/ImageRegionIterator.cxx
    Examples/Iterators/ImageRegionIteratorWithIndex.cxx

If you want to extract the ROI as a new image, then you may be
interested in Code/BasicFilters/itkExtractImageFilter.h.

Hope this helps.

Regards, Dan
