Comparison of faster R-CNN algorithm with contour counting method. (a) Comparison of the counting results between faster R-CNN based on deep learning and contour counting based on thresholds for fluorescent images at the concentration of 1.1 × 103 CFU/mL. (b) The counting situation of contour counting method on fluorescent images. (c) The counting situation of faster R-CNN on fluorescent images. (d) Optimization of the ratio of the training set to the validation set. (e) Optimization of the training epoch.
