I have two segmentations and the size of the references volume of these segmentations are different from each other. Now I want to combine these two segmentations and edit them in the Segment Editor module. How is it possible?
How can I manage different sizes of my segmentations? Should I make the sizes of both segmentations exactly the same, if yes, how should I do this?
Thanks in advane
I could manage to somehow combine my segmentations. Now, when I go to segment editor, the quality of my segments are considerably different. This is a screenshot:
I added the segmentation of white part to the segmentation of green part and it can be seen that the qualities are very different. I should note that the quality of white part was not this bad when it was in separate segment. What should I do to solve this problem?
Also, now when I want to paint in segment mesher it takes a lot of time for the combined segmentation while when I want to paint each segmentation separatetly, it is very fast.
Any helps would be greatly appreciated.
You can drag-and-drop segments between segmentations in Data module. The segmentation will be resampled to the resolution of the segmentation’s internal labelmap representation at the next editing operation (not immediately to allow lossless copying/moving of segments between segmentations). If the quality is not sufficiently good then follow these instructions.
Meshing two segments is a harder problem than one, so it is normal that meshing takes more time. You can adjust meshing options to find a good balance between meshing speed, memory usage, and size and quality of the created mesh.
Thanks for your response @lassoan. I made a mistake in my previous question, I mentioned “segment mesher” but in fact I meant “segment editor”. I wanted to say that when I want to paint combined segmentation in segment editor, the time is too long, but when I paint each of my segmentations separately (before combination) in segment editor, it is very fast. Do you have any comments in this regard?
Your help is greatly appreciated.
Slowdown is expected if you copy a segment to a finer resolution segmentation or the two segments are far from each other, but it is hard to tell what is the best way to make the performance better without seeing your data. If you can share an example data set the demonstrates the issue (upload somewhere and post the link) then we can take a look.
Thanks for your response @lassoan. Sure, I will spend a little more time on my model and if I was not able what I want, I will share a sample dataset so that you can take a quick look. Thanks a lot.
