Abstract: A full-size training image is reduced by an image reduction unit (11) and input to an FCN (Fully Convolutional Neural Network) computation unit (13), and the FCN computation unit (13) performs calculation under a set filter coefficient and outputs a reduced label image.

By repeating learning under the control of the learning control unit 17, it is possible to generate a learning model for performing optimal segmentation including an error generated at the time of image enlargement. Further, by including the image enlargement processing in the learning model, a full-size label image can be output, and the accuracy evaluation of the model can also be performed with high accuracy.
