Fig. 4: Comparison of two differently clustered NBED patterns.

From: Unsupervised machine learning and cepstral analysis with 4D-STEM for characterizing complex microstructures of metallic alloys

Fig. 4

Prior NMF + NBED clustering result from Fig. 3d with an individual diffraction pattern from the top left (light blue cluster) and top right (orange cluster) region near the Han precipitate. The red arrows point toward the pattern intensity’s center-of-mass, indicating local sample bending around the Han precipitate.
