I want to know how the 'ccdc' algorithm, which is deployed on GEE, detects changes.

Does the algorithm use the method on the left, the method on the right, or some other method?

enter image description here

The function of ccdc in Google Earth Engine is:

ee.Algorithms.TemporalSegmentation.Ccdc()

It's somewhere in between, since it's derived from the V12.30 MATLAB implementation, and you can manually specify the number of observations required to detect a change (it defaults to 6). There is no angle adjustment.
