三维显示图像的串扰评价方法与理论建模(特邀)

A Crosstalk Evaluation Method and Theoretical Modeling for Three-Dimensional Display(Invited)

裸眼三维(3D)显示技术可使观众无须佩戴眼镜就可以观看到具有立体效果的图像,是3D显示领域研究的重点。目前,业界尚缺少衡量裸眼3D显示器显示3D图像质量优劣的方法,从而严重制约了光场显示和内容生成的发展。本课题组提出了裸眼3D显示中串扰的客观评价指标,重点考虑了相邻像素间颜色值相近致使视点信息复用的情况。实验结果表明,所提评价指标与主观评分值的相关系数可以达到88%以上,指标值与人眼视觉对视差图像的串扰感知高度一致。

Glasses-free three-dimensional(3D)display technology enables viewers to see stereoscopic images without visual aids,which is a focus of 3D display research.At present,the lack of image quality assessment methods for 3D display seriously restricts the development of light field display and content generation.In this study,objective evaluation metrics for crosstalk of glasses-free 3D display are proposed,considering the information reuse caused by the similar color values between adjacent pixels.The experimental results show that the correlation coefficient between the proposed metrics and subjective evaluation values is higher than 88%,indicating that the proposed metrics can detect the crosstalk perceived by the human eye.
