Erik Fröjdh	8551281eb7	Cleaned up Pedestal (#370) ... - renamed pedestal.hpp to bind_Pedestal.hpp for python bindings - variance is now always calculated in double and made private - cost correctness in a few places - removed push_fast and explicit updates of mean from Pedestal. If performance is needed use FastPedestal - Pedestal no longer caches std	2026-09-14 16:27:53 +02:00
Erik Fröjdh	eddb919328	FastPedestal + optimizations in the cluster finder (#341) ... Optimized pedestal tracking with FastPedestal and performance improvements to the cluster finder. - ~2x faster hitting 14k FPS on benchmark dataset on 16 core threadripper pro **Changes** - No bounds check on interior of frame. (only within half of a cluster) (~15% improvement) - Cache threshold (std*n_rms) Biggest improvement comes from not computing std for each access - Cache pedestal subtracted frame - Switched to FastPedestal which assumes we reached steady state **Things tried but rejected:** - Always store cluster values, commit on val==max (~15% drop in frame rate) **Options** - using 16 bit clusters and 16 bit pedestal. (slows down the single threaded case but allow us to reach 12k with multi threading) **Other notes on performance** - Passing in memory frames from python and doing nothing: 0.8us/frame - Passing + pedestal subtraction: 28us/frame - Passing + pedestal + cluster finding (no store): 652us/frame - Passing + pedestal + cluster finding: 886 us/frame	2026-09-01 18:41:12 +02:00
