I'm trying to use CP to recognize a myelin sheath in a TEM cross-section image of axon bundles. I'm doing some voodoo to simulate a fluorescent image and for the most part it works. The problem I'm running into is that when recognizing the actual myelin, the IDSecondary module isn't expanding enough to grab the entire region, but it should. I can't for the life of me figure out why it's segmenting where it is. The attached image shows the result no matter the settings I use in ID Secondary.
