Fig. 2: Accuracy of AI inference compared to conventional iterative phase retrieval.
From: Deep learning at the edge enables real-time streaming ptychographic imaging
a Shows the cumulative phase from the workflow. The result is obtained by stitching together individual AI inferences of the entire scan as described in the “Methods” section. b Shows the results of iterative phase retrieval on the same data. c Shows the line profile comparison of the phase obtained with AI inference and iterative methods. The position of the line cut is indicated by the white dashed line in (a). The scale bar is 500 nm. Source data are provided as a Source data file.
