Efficacy of SMAXI's gray-scale intensity normalization module. (a-1) A raw high-speed X-ray image of an L-PBF process of Ti-6Al-4V plate sample, exhibiting low contrast and background artifacts. (a-2) The normalized frame demonstrating sharpened image boundaries that clearly isolate the keyhole-shaped vapor depression and the surrounding melt pool. (b-1) A raw projection image of in situ CT experiment on fatigue corrosion of Al7075, with horizontal stripe artifacts present (Stannard et al., 2017View full citation). (b-2) The pre-processed output, successfully flattening the illumination gradient to reveal the underlying fatigue crack propagation.
