How to select the appropriate dilation parameter?

I have a true oolor image. I want to dilate the image for further processing it. There are different types of dilation parameters like disc,line,diamond etc.. I do not know which is the appropriate one and also what value to give as radius/length etc for my image. Can anyone suggest ???

Trial and error. When it's best for you, you'll know it. There is no one overall universal answer to that question, like "disk of radius 11", that applies to every color image ever generated on the planet (or off the planet).
