Satellite Image Registration Still Uses Classical Cross-Correlation; Modern Matchers Lack a Benchmark
gabriberton · x · 2026-11-10
A remote sensing engineer points out that Sentinel-2 and Landsat geometric registration in production still relies on classical cross-correlation, while modern deep image matchers—despite strong eval results—haven't been validated at scale on satellite imagery. The thread proposes a free paper idea: benchmark modern image matchers at production scale on satellite imagery against the methods actually used in production.
