AI Technical Summary

Technical Problem

Existing technologies, such as those described in Patent Documents 1 and 2, fail to faithfully express motif elements on building surfaces using multiple types of panels with different colors, limiting their application to building facades and other components.

Method used

An image style conversion device and program that generates a styled image by inputting a base image and a styled image into a style conversion model. The device divides the styled image into regions based on panel shapes, derives average colors for each region, and replaces these colors with those of panels that have the greatest similarity, using achromatic panels with different brightness levels.

Benefits of technology

This solution enables a more faithful expression of motif elements on building surfaces, effectively addressing the limitations of previous technologies by accurately integrating motif elements with the color and shape of building panels.

Abstract

To provide an image style conversion apparatus configured to faithfully represent elements of an intended motif on a surface of a member of a building, and an image style conversion program.SOLUTION: An image style conversion apparatus 10 includes: a generation unit 11A which generates a style-added image by inputting a base image and a style image to a style conversion model 13B which is configured to receive, as input information, the base image which is a base of an image to be represented on a surface of a member of a building with multiple kinds of panels different in color and the style image with elements to be added to the base image as a motif, and to output a style-added image, as output information, obtained by adding the elements to the base image; a derivation unit 11B which divides the style-added image into a plurality of areas in accordance with shapes of the panels, and derives an average color of the subdivided areas; and a replacement unit 11C which replaces colors of corresponding areas with a color of a panel having a highest similarity between colors of each area and colors of each kind of the panels.SELECTED DRAWING: Figure 3
