martin-boettcher commented 1 year ago

Idepix MSI algorithm re-implemented as a single-pass loop over the pixels with a multi-line accumulator to avoid full-image intermediate results. Optimisation has pushed down S2CloudPostprocess from more than 70% to 15% of the processing time. Memory consumption is reduced. Implemented in version 9.0.6 .
