基于双眼视差的立体视觉不改变目标与掩蔽刺激之间的信噪比,但能使不同的刺激被知觉在不同的深度位置上以降低目标信号所受到的掩蔽作用。本综述在总结前人双眼去掩蔽研究的基础上,强调深度维度上的视觉注意在这种主观空间分离去掩蔽过程中所起的重要作用,并介绍了双眼去掩蔽在现代科技领域中的典型性应用。最后,结合听觉主观空间分离去掩蔽的研究进展,本综述认为主观空间分离去掩蔽是大脑处理复杂刺激场景的一个基本功能。
Binocular vision based on binocular parallax does not change the signal-to-noise ratio between the target and masking stimuli, but enables different stimuli to be perceived at different depth positions to reduce the masking effect of the target signal. On the basis of summarizing previous research on masking of both eyes, this review emphasizes the important role of visual attention in the deep dimension in this subjective spatial separation and masking process, and introduces the typical case of double masking in modern science and technology Sexual application. Finally, combined with the research progress of de-masking auditory subjective spatial separation, this review concludes that subjective spatial de-masking is a basic function of the brain in handling complex stimuli scenarios.
