Claim 0:
1. A cell image segmentation method using scribble labels, comprising:
iteratively pre-training via an image segmentation network (U-Net) using a cell image and scribble labels indicating a cell region and a background region as training data;
calculating an exponential moving average (EMA) of image segmentation prediction probabilities at a predetermined interval during the pre-training;
self-training by assigning the cell region and the background region for which the EMA of image segmentation prediction probabilities is over a preset threshold to be a pseudo-label; and
iteratively refining the image segmentation prediction probability based on a scribbled loss (Lsp) obtained through a result of the training and an unscribbled loss (Lup).
