摘要

提出了一种用于虚拟视图合成的自适应色彩校正方法。它解决了自由导航系统中的典型问题——不同相机获取场景时所捕获的视图的光照不同。该方法对两个真实视图中可见物体的局部颜色特征进行调整。这种方法可以显著减少虚拟视图中颜色伪影的数量和可见性。在12个多视图测试序列上对该方法进行了测试。研究结果表明，所提出的色彩校正方法提高了虚拟视图的PSNR、SSIM和主观评价的质量。

ADAPTIVE COLOR CORRECTION IN VIRTUAL VIEW SYNTHESIS

In the paper an adaptive color correction method for virtual view synthesis is presented. It deals with the typical problem in free navigation systems – different illumination in views captured by different cameras acquiring the scene. The proposed technique adjusts the local color characteristics of objects visible in two real views. That approach allows to significantly reduce number and visibility of color artifacts in the virtual view. Proposed method was tested on 12 multiview test sequences. Obtained and presented in the paper results show, that proposed color correction provides increase of the virtual view quality measured by PSNR, SSIM and subjective evaluation.
