Design and Implementation of Style-Transfer Operations in a Game Engine

초록

The image style transfer operations are a kind of high-level image processing techniques, in which a target image is transformed to show a given style. These kind of operations are typically acquired with modern neural network models. In this paper, we aim to achieve the image style-transfer operations in real time, with the underlying computer games. We can apply the style-transfer operations to the all or part of rendering textures in the existing games, to change the overall feeling and appearance of those games. For a computer game or its underlying game engine, the style-transfer neural network models should be executed so fast to maintain the real-time execution of the original game. Efficient data management is also required to achieve deep learning operations while maintaining overall performance of the game as much as possible. This paper compares several aspects of style-transfer neural network models, and its executions in the game engines. We propose a design and implementation way for the real-time style-transfer operations. The experimental result shows a set of technical points to be considered, while applying neural network models to a game engine. We finally shows that we achieved real-time style-transfer operations, with the Barracuda module in the Unity game engine. © (2024), (Science and Information Organization). All rights reserved.
