No need to do the signal trandformation?

This is an interesting metric for diffusion tensor images.
There is a question about the signal transformation in the beginning of LDH calculation.
Since LDH is calculated with Kandell formula, it seems that, even without the signal transformation (equation 1 in the paper), we can get exactly the same LDH map.
In this sense, we can get LDH map from the raw data (after correcting some artifacts).
