When the images presented to each eye differ in sharpness, the fused percept remains relatively sharp. Here, we measure this effect by showing stereoscopic videos that have been blurred for one eye, or both eyes, and psychophysically determining when they appear equally sharp. For a range of blur magnitudes, the fused percept always appeared significantly sharper than the blurrier view. From these data, we investigate to what extent discarding high spatial frequencies from just one eye's view reduces the bandwidth necessary to transmit perceptually sharp 3D content. We conclude that relatively high-resolution video transmission has the most potential benefit from this method.
当呈现给每只眼睛的图像在清晰度上存在差异时,融合后的感知仍然相对清晰。在此,我们通过展示对一只眼睛或两只眼睛进行模糊处理的立体视频,并通过心理物理学方法确定它们何时看起来同样清晰,来测量这种效果。对于一系列模糊程度,融合后的感知总是比更模糊的视图明显更清晰。从这些数据中,我们研究了仅从一只眼睛的视图中丢弃高空间频率在多大程度上降低了传输感知清晰的3D内容所需的带宽。我们得出结论,相对高分辨率的视频传输从这种方法中获得的潜在益处最大。
