Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a line drawing automatic coloring program capable of automatically coloring a line drawing image.

SOLUTION: A line drawing automatic coloring apparatus incorporates line drawing data into a computer, performs the reduction processing of the line drawing data to obtain reduction line drawing data with a predetermined reduction size, perform a first coloring process for the reduction line data based on any one of a plurality of first learned models which has been made to learn a coloring process in advance for the line drawing data with the reduction size by means of sample data, and performs a second coloring process for original line data to which colored reduction data after a coloring process by the first coloring process and original line drawing data are applied as inputs based on any one of a plurality of second learned models made to learn a coloring process in advance for the sample data in which the sample data and colored reduction sample data colored in the first coloring process for the sample data are applied to the plurality of second learned modules as inputs.

【課題】線画画像に対して自動で着色が可能な線画自動着色プログラムを提供する。
【解決手段】線画自動着色装置は、コンピュータに、線画データを取得し、線画データに対して所定の縮小サイズとなるように縮小処理を行って縮小線画データを得て、サンプルデータを用いて縮小サイズの線画データに対する着色処理を予め学習させた複数の第1学習済モデルのうちの何れか1つに基づいて縮小線画データに対して第1着色処理を行い、サンプルデータとサンプルデータに対して第1着色処理において着色を行った着色済縮小サンプルデータを入力としてサンプルデータに対する着色処理を予め学習させた複数の第2学習済モデルのうちの何れか1つに基づいて、第1着色処理による着色処理後の着色済縮小データと元の線画データとを入力として、元の線画データに対して第2着色処理を行う。
