Dear all, I would like to quantify the shape of an soft tissue organ. However I am not sure what would be the best method to use. Working with soft tissue organs, I am having two problems: one is the absent of landmarks, and the other is that sometimes the preparation of the specimens may cause some deformations on the shape. Is there any way to get around this situation?
Dear Julia, I think that your question is a bit tricky as not everyone likes semilandmarks and the like. My idea is that if the organ you're interested in is so soft and flexible that you cannot realy imagine a "standard" situation, then it's a bit too tricky and studying shape variation might even be not particularly meaningful in itself. On the other hand, if there is some sort of "normal status" that you can imagine your organ in (and you can get your organ in this status), then you can use sliding semilandmark or other outline methods. About the deformation, apart the obvious of avoiding it, if it's somewhat predictable then maybe it can be modeled and removed from your data. Sorry if I sound too vague but your question is quite general... I hope that the answer is of some help, though...
