基于立体视频图像质量的评价方法研究

Research on Image Quality Assessment of Stereoscopic Video

在2D视频图像质量评价方法基础上,针对立体视频图像的主观感知特性,提出了一种基于立体视频图像质量的客观评价算法模型。该模型采用最小二乘法将主观评价值与反映3D图像画面质量的A-PSNR指标以及反映立体感的D-PSNR指标进行线性回归拟合。实验结果表明,本文提出的立体视频质量客观评价模型的预测值与主观评价结果具有较好的一致性,即符合主观感觉,因此能够有效地反映立体视频图像的质量。

Based on objective evaluation methods of 2D video quality assessment and subjective perceptual characteristics of stereoscopic images, an objective image quality assessment metric for stereoscopic video is proposed in this paper. The linest regression analysis is used to integrate the two evaluation indicators which are A-PSNR and D-PSNR with subjective scores. Experimental results show that the proposed objective video quality assessment metric can achieve consistent stereoscopic video quality evaluation result with subjective scores.
