<p class="MsoNormal"><span lang="EN-CA">Hello ITK users,</span></p>
<p class="MsoNormal"><span lang="EN-CA"><span style=""> </span><span
style=""> </span>I am currently working with strain
tensor field images.<span style=""> </span>I essentially have
images with pixels that contain within them a second order tensor,
strain.<span style=""> </span>I wish to smooth the images and
resample the
images on to a finer grid.<span style=""> </span>I am unsure
how to work with these images using ITK.<span style="">
</span>There does not seem to be any facilities designed to work with
these type
of tensor fields.<span style=""> </span>Could someone please
suggest what features I might use?</span></p>
<p class="MsoNormal"><span lang="EN-CA"><!--[if !supportEmptyParas]--><!--[endif]--><o:p></o:p></span></p>
<p class="MsoNormal" style="text-indent: 0.5in;"><span lang="EN-CA">I
have specific
rules as to how the tensors (pixels) should be added and scalar
multiplied.<span style=""> </span>These rules are the primary
reason I think that these images are not easily processed within ITK.<span
style=""> </span>I was wondering if I could easily
interpolate and resample these images by deriving a class from the
SymmetricSecondRankTensor parent class and redefine the scalar
multiplication
and tensor addition and then simply use the existing resample and
smoothing
filters and appropriate interpolation functions to accomplish my task?
What I
am essentially asking is, can I make a tensor class that obeys the
rules that I
have mentioned above and then use this as a pixel type in a regular
image and
expect smoothing and resample image filters to work?</span></p>
<br>
Any help will be much appreciated. Thanks<br>
