On the Improvement of Viewer's Impression for Videos by Non-photorealistic Rendering

Abstract

In this paper, we report the effects of improving viewer's impression for videos by non-photorealistic rendering. Our subjective test, first, reveals that non-photorealistic videos improve viewer's impression on several sub-elements in the original photorealistic videos without detracting overall visual preference. We, then, confirm that non-photorealistic videos reduce perceived jerkiness even in the low frame rate compared to the original photorealistic videos. We also report the subjective test methods designed for the evaluations.
