摘要

为了更直接地评价和比较立体显示中的串扰现象

结合图像内容对灰阶串扰进行了单一数值量化。提出的平均灰阶转换概念

选取了多幅具有代表性的立体图像

并对立体显示图像中每一灰阶转换组合出现的概率进行了统计

得到的平均灰阶转换也是以矩阵的形式出现。灰阶串扰单一数值量化就是利用平均灰阶转换矩阵对灰阶串扰矩阵进行加权平均

加权平均后的串扰矩阵中所有值相加得到单一的串扰评价值。提出的灰阶串扰单一数值量化方法充分考虑了图像内容的影响

得到的灰阶串扰单一数值评价结果更加客观、准确。同时

研究结果对串扰现象的优化以及视觉舒适度的提高具有指导和推动作用。

Abstract

To evaluate and compare the crosstalk phenomenon more directly in stereoscopic displays

single value evaluation method which combined with image content is applied to gray-to-gray crosstalk. The proposed average gray level transitions concept chooses a group of representative three dimensional (3D) images and applies statistic analysis to derive probability of each gray level transition which also exist in matrix form. The single value evaluation of gray-to-gray crosstalk is using average gray level transitions matrix to weight gray-to-gray crosstalk matrix and the values of weighted averaged gray-to-gray crosstalk matrix are added as the final single value for crosstalk evaluation. The proposed single value evaluation method of gray-to-gray crosstalk fully considers the effect of 3D image content on crosstalk

and the derived single value crosstalk evaluation is more objective and precise. The investigation result helps with the optimization of crosstalk and the improvement of visual comfort.
