Fig. 6: Reconstruction error with varying field of view.
From: Unsupervised deep denoising for four-dimensional scanning transmission electron microscopy
Violin plots of the histogram of reconstruction errors for the Frobenius norm (the lower the better) for (a) SrTiO3 and (b) Y2Ti2O7 and for the Pearson cross correlation coefficient (the higher the better) for (c) SrTiO3 and (d) Y2Ti2O7. Results are compared for different fields of view as indicated by the number of patterns, and between the TSVD and CNN approaches to denoising. The vertical blue lines indicate the correspondence between the number of patterns and the field of view, with the first blue line from the left corresponding to a single unit cell field of view, the second to two unit cells, and so forth. The reconstruction errors are lower in the network approach for the smaller fields of view, demonstrating its efficacy in exploiting geometric flow for signal recovery.
