Color asymmetry in 3D imaging: Influence on the viewing experience
3D Research(2012)
摘要
Because the chain of events in 3D imaging is vulnerable to different context- and technology-specific variables, it is important to understand the extent to which users can accept feature-specific differences between scenes without a decrease in the (observed) image quality. Twenty participants were asked to view natural stereoscopic still images and evaluate how different combinations of color asymmetries affect the overall viewing experience, the naturalness of the image and the depth perception. As expected, an increase in color asymmetry between the viewer's left-eye and right-eye images decreased the image quality evaluation scores. Certain color-channel-specific changes, such as a decrease in blue values, were more acceptable than others, and some content-specific features, such as a brownish or greenish background, were less sensitive to changes compared to close-up images with brighter objects and backgrounds.
