Write now I am writing my own blob detection software for linux it follows the client/server model and is modular to accommodate with methods other than FTIR. Currently I am only working on the FTIR module (because that is what I am using). I am pretty familiar with the standard filters, grayscale, brightness, contrast etc. My question is what other types of filters might people need, I would like to have quite a large to list to pick from.

NOTE: I am currently using C with magickcore, so any filters that could be applied with magickcore would be best.
