  • Patent number: 11908133
    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.

  • Patent number: 11893579
    Abstract: Disclosed is a method of reducing smart contract fees for a decentralized application (DApp). A parameter of a request reception event and a public key of a user are stored in a task queue of a computation server. The computation server performs a task requested by the user, calls a state change function for the performed task from a smart contract, and transmits a transaction result to the user when the transaction result is returned. The user pays, to the smart contract, a fee corresponding to the generation of the request reception event, and the computation server pays, to the smart contract, a fee corresponding to a state change of the smart contract. Thus, by minimizing and uniformizing a fee to be paid by a user of a DApp system, it is possible to increase accessibility to a corresponding DApp.
