<div>Hello.</div>
<div>I am beginning to feel a bit more at home in itk/vtk now. There are still a zillion things to learn about it, but its getting a bit better. So now i have decided that i want to try and make my own filter to get more acquainted with the whole pipeline approach.
</div>
<div> </div>
<div>I have read chapter 13 in the itksoftwareguide, and i have thought about a approach to make my filter. I was hoping some of you experts would tell me if i am completely off, or if my idea is okay.</div>
<div>My situation is this: </div>
<div>I have a greyscale volume consisting of 182 slices that are 182x218 pixels of a brain.</div>
<div>I have a mask of corresponding size with values 0 and 255 for the positions of greymatter</div>
<div>I have a mask of corresponding size with values 0 and 255 for the positions of whitematter</div>
<div>I have a mask of corresponding size with values 0 and 255 for the positions of CSF(brainfluid)</div>
<div> </div>
<div>Basically i want my filter to combine the 3 masks to a single image, so that i can visualize this image in vtk with different colors for greymatter, whitematter and CSF.</div>
<div> </div>
<div> </div>
<div>Making a filter (lets call it masking)that subclasses ImageToImageFilter, and then takes 2 input images and somehow combining them to a single image by just adding them together.</div>
<div> </div>
<div>I then want to make a compositefilter that actually makes a pipeline of 2 masking filters, taking first 2 masks, combining them in the masking filter, takes the output of this and combine it with the third mask using again the masking filter, and then outputting the final masked image.
</div>
<div> </div>
<div>Does this sound feasible, and more important is this a good approach?</div>
<div>I hope for some feedback.</div>
<div> </div>
<div>Many regards and thank you</div>
