In Slicer using the Simple Filters module, I’ve been doing binary thresholding of a CT volume:
But I want thinner walls so I thought I could fix this with binary erosion:
The problem is that the black cells starts to grow into each other and the walls disappears (red lines in picture). Is there a way to inflate the black cells without growing them into each other so that the cell topology is preserved? I just want thinner walls. The result doesn’t need to look exactly as the initial image.
I have the problem of finding a good thresholding value on the original CT volume: My thresholding either removes visual walls between the cells or fills up small cells. Could there be a way to postprocess my initial image (for example sharpening edges/shapes?) so I can make a binary image that looks like how we humans see the cells and walls?
