Abstract: A cell image segmentation method using scribble labels includes 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). Accordingly, it is possible to achieve cell image segmentation with high reliability using only scribble labels.

Abstract: A method for matching between high altitude platform (HAP) and unmanned aerial vehicle (UAV) in space-air-ground integrated network includes determining if there is an unmatched UAV in the space-air-ground integrated network including at least one UAV and at least one HAP; requesting matching to an unmatched m-th (where m is a natural number) UAV from an n-th (where n is a natural number) HAP having an unconnected antenna in a presence of the unmatched UAV; determining if the m-th UAV is matched with another HAP; comparing a priority of the n-th HAP with a priority of the matched HAP, in case of the m-th UAV being matched with another HAP; and matching the unconnected antenna of the n-th HAP with the m-th UAV, in case of the priority of the n-th HAP being higher than the priority of the matched HAP.
