Title:
MODEL LEARNING DEVICE, MODEL LEARNING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/129716
Kind Code:
A1
Abstract:
The present invention makes it possible to learn an image generation model which can generate an accurate image down to the details thereof. A partitioning unit 22 outputs image data corresponding to a plurality of partitioned regions for each instance of L instances of partitioning processing performed on a learning image I0 and a semantic layout image S0. A reduction unit 26 reduces the semantic layout image S0 and the plurality of region images to a prescribed size. A learning unit 28 learns an image generation model 32 such that: upon the input to a first generator G2 of images obtained by the reduction of each of the plurality of regions obtained by partitioning the semantic layout image S0 by L-1 instances (0 ≤ 1 < L) of partitioning processing, an (l+1)-th generator Gl+1 generates an image corresponding to each of the plurality of regions obtained by partitioning the learning image I0 by L-1 instances of partitioning processing; and upon the input to the first generator G2 of an image obtained by the reduction of the semantic layout image S0, an (L+1)-th generator GL
+1 generates an image corresponding to the learning image I0.
