Method and device for segmenting objects in images using artificial intelligence

A device for segmenting objects in an image using artificial intelligence, comprising:

• an input device for obtaining an image including at least one object;
• a storage device for storing a segmentation model that segments objects in the image acquired by the input device;
• and
• an arithmetic device inputting the image acquired by the input device to the segmentation model and segmenting objects in the image based on values output by the segmentation model,
• wherein an image containing at least one object is used as learning data, the size of objects in the learning data is estimated as part of the learning process, different weightings are given to pixels of which the objects consist according to the estimated size of the objects, and the segmentation model is trained based on a loss function in which the given weightings are considered, a size-weighted loss function.
