A Subjective Study of Multi-Dimensional Aesthetic Assessment for Mobile Game Image.

Nowadays, mobile gaming has become one of the most rapidly developing fields boosted by fast-evolving techniques, which also gradually becomes one of the biggest parts of modern digital entertainment. With the exponential growth of users, published mobile games, and higher expectations for gaming experiences, multi-dimensional aesthetic assessment is essential in providing guidance for graphic/game developers, quality control of the overall gaming system, and achieving a better trade-off between gaming image quality and the rendering complexity (limited by the device performance). So far, most of the relative researches have been limited to only one dimension evaluation e.g., quality assessment considering streaming artifacts, which neglects other important aesthetic-related perspectives. In this paper, a comprehensive subjective study is presented considering multi-dimensional aesthetic factors (i.e., the fineness, color harmony, colorfulness, and overall quality) of mobile gaming images. Throughout extensive conducted experiments on the collected large-scale dataset, we discuss the relationships between different dimensions, and benchmark different image metrics designed for various purposes.
