摘要
结合人眼视觉特性提出了一种改进的极限法—逐级步长逼近法,利用逐级步长方法首次定量研究亮度因素对观看双目立体图像舒适度的影响。通过大量实验定义了双目立体图像舒适亮度匹配图和舒适亮度差异图,并进一步验证了2图的普适性,根据两图判定立体灰度图像是否舒适的准确率达到92%以上。实验结果能够更好地反映立体灰度图像的舒适度,为立体图像舒适度的主客观评价提供了依据。
Combining the characters of human visual system,a new method of multi-step approximation is proposed in this paper firstly to research quantitatively the brightness influence on the stereoscopic visual comfort.This method can get the comfortable brightness matching and difference maps,and verify the universal applicability of both two maps.The accurate rate of whether one stereoscopic gray image is comfortable is more than 92%.Experiment results show that the stereoscopic gray image comfort better and provide a base for the subjective and objective assessment of binocular image pairs.
