Comparison of the detection accuracy between the sliding window method (SWM) and mask region-based convolutional neural network (Mask-RCNN) method using the same image. A, B, and C show the SWM, while D, E, and F show the Mask-RCNN (at the end of epoch 40). A, B The non-nuclear regions (arrows) are indicated in red, while C discriminates the nucleus regions in red but in a wider range. By contrast, D, E, and F are only identified as cell nuclei in blue
