Sorry, I do not know what you are asking. Can you explain a bit further? What does your question have to do with the cylinderize script?

Then you first need to crop to the individual elements. What defines the separation? Perhaps one element is always in the top half, and the other is in the bottom half. Or perhaps they are always separated by horizontal white.

If you can assume that there are rows of text separate by white space between, then you can average the image down to one column, then search to find white between areas of gray. Then crop horizontally on the white spaces and trim to remove excess white.
