a vADF image of the large FoV scan region showing several needle-shaped precipitates embedded in the matrix. b Cepstrum + NMF clustering result for K = 4, which was automatically determined again by the elbow point method (Fig. S6). c Averaged NBED and cepstrum patterns from (b). Scale bars are 10 nm−1 for the NBED patterns and 5 Å for the cepstrum patterns.
