Fig. 6: Visualizing effect of cepstral analysis on clustering.

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

Fig. 6

NMF + cepstrum clustering result from Fig. 5c with cepstrum patterns corresponding to the diffraction patterns in Fig. 4 are displayed. The cepstral transform successfully decouples the phase information from the effects of sample bending, and the patterns’ intensities are centrosymmetric.
