Fig. 3. Images captured using the microorganism monitoring system.

a Whole agar plate image of mixed E. coli and K. aerogenes colonies after 23.5 h of incubation. b Example images (i.e., amplitude and phase) of the individual growing colonies detected by a trained deep neural network. The time points of detection and classification of growing colonies are annotated with blue arrows. The scale bar is 100 µm
