Claim 10:
11. A cell image segmentation device using scribble labels, comprising:
a warm-up unit to iteratively pre-train 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;
a probability prediction unit to calculate an exponential moving average (EMA) of image segmentation prediction probabilities at a predetermined interval during the pre-training;
a self-training unit to self-train 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
a refinement unit to iteratively refine the image segmentation prediction probability based on a scribbled loss (Lsp) obtained through a result of the training and an unscribbled loss (Lup).
