IIRC, CP extends Platt.

That's what the CP guys say. :)

I would even say that Platt generalizes CP. Whereas CP focuses on the empirical distribution of prediction score only around a particular location at the tails, e.g. at confidence level 5%, Platt scaling tries to mold the whole empirical distribution into calibrated probabilities -- thus Platt considers the whole range of the distr of scores.
