comment How to determine distance of periodic features in measured dataset
In your question you seemed to suggest that the cross was just an example of something to look for: "there are some periodic features (in this case a cross)". 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).

@Wally To be sure: I'm not downvoting this. Note that this site is not about us doing your work, but more about us helping you get around problems and questions you encounter. Some effort from your side is appreciated.

@kay Well, at least you need to define what makes up a feature, otherwise this problem seems underdetermined.

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.
