Method for measuring volume of organ by using artificial neural network, and apparatus therefor

A method, performed by a computing device, of measuring a volume of an organ, the method comprising:

• acquiring a plurality of captured images of the organ and photographing metadata and preprocessing the plurality of images to acquire a plurality of image patches of a specified size;
• inputting the plurality of image patches into a three-dimensional (3D) convolutional neural network (CNN)-based neural network model and estimating an organ region corresponding to each of the plurality of image patches;
• measuring a volume of the organ by using an area of the estimated organ region and the photographing metadata;
• measuring an uncertainty value of the 3D CNN-based neural network model and uncertainty values of the plurality of images based on a result of estimating by the 3D CNN-based neural network model;
• modifying at least one of the plurality of images based on the uncertainty values of the plurality of images;
• and
• modifying a labeling policy of the 3D CNN-based neural network model based on the uncertainty value of the 3D CNN-based neural network model.
