Deep Learning Based Tongue Prickles Detection in Traditional Chinese Medicine

Figure 2

Prickle detection workflow. Blue rectangles represent images, and yellow rectangles represent image processing. First, in tongue segmentor, we introduced Swin Transformer, a state-of-the-art computer vision segmentation neural network, to mat the tongue region out of the raw picture. Second, in tongue partition, the tongue is partitioned into four areas: root, margin, tip, and center. Third, in data prelabeling, a spot detector is applied based on tongue areas. Fourth, elaborate manual annotation is conducted with the help of TCM doctors. Fifth, to fully embody the advantages of the neural network, a super-resolutionfaster-RCNN based detector is deployed to detect the prickles from a matted tongue image.
