That was what I was referring to when I wrote "defining the feature". I wasn't referring to a characteristic of this feature (such as center or bounding box).

Apr 20 comment How to determine distance of periodic features in measured dataset @kay Well, at least you need to define what makes up a feature, otherwise this problem seems underdetermined.

Apr 20 comment What is the good source to study advanced custom coding in Mathematica Apr 20 comment rename files randomly You'd need RenameFile, and a bit of FileNames, FileExtension,FileBaseName, and FileNameSplit. Read the documentation on these functions, play with them, and come back if you encounter problems.
