Hi,<br>
<br>
I was intending to use SparseImages in ITK. However, its been hard frustrating search. Firstly, the ITK doc makes no mention of it in the entire pdf. After some searching, I found a source in the InsightToolkit-3.14.0/Testing/Code/Common/itkSparseImageTest.cxx.<br>
<br>
However, it seems that it is not possible to interchangabily use SparseImages and normal itk::Images.<br>
I tried writing a SparseImage via FileWriter and also tried running some filters on them. But it spits out countless errors.<br>
<br>
I have slightly modified the itkSparseImage.cxx to illustrate that point. I have attached that source code in this post. Pls run it and suggest if there any changes I can make.<br>
<br>
<br>
<br>
My Questions : 1) Does ITK discourage the use of itk::SparseImage cos it has some inherent deficiencies ? There doesnt seem to be any documentation on it.<br>
2) Is it possible to use SparseImages like normal itk::Images. Like I/O operations or usage of common filters. I saw there is only one filter,FiniteDifferenceSparseImageFilter which looks like specifically written for SparseImages.<br>
<br>
3) If the itk::SparseImage is not able to do the above, are there any alternatives ???<br>
<br>
Even after countless googling, the online community didnt yield any concrete answers ?<br>
<br>
Thanks for the help folks.<br></blockquote><div><br></div><div>It was not clear from the documentation what the requirements for the NodeType class were.
