Artifact-free crosstalk reduction in light field display based on multi-view image correlation

Recently, 3D light field (LF) display technology is increasingly being applied for commercial products, as 3D representations are widely used in various fields such as game and metaverse applications. Inter-view crosstalk, which is caused by one or more unintended views being added to the intended view, is a major factor that induces image quality degradation and visual discomfort in 3D LF displays. In this paper, we propose an algorithm that provides optimal crosstalk reduction while preventing color over-shoot artifact that is common in conventional methods. The proposed algorithm applies an optimized crosstalk reduction filter, determined adaptively for every pixel in the image, based on the correlation between neighboring LF views. The experimental results using a LF display prototype show that the proposed method can reduce crosstalk effectively without causing color over-shoot artifacts and reduces crosstalk by 20.4% compared to the previous method.
