基于双眼视差的立体视觉去掩蔽效应

Stereopsis-Based Binocular Unmasking

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。

Without affecting the signal-to-noise ratio, the binocular disparity-based stereopsis induces perceived depth separation between the target and the masker （s）. The perceived separation improves detection and/or discrimination of the target, leading to the so-called binocular unmasking. This review summarizes previous studies related to binocular unmasking and particularly emphasizes that the allocation of selective visual attention in depth plays a critical role in binocular unmasking. Most importantly, considering that the unmasking effect of perceived spatial separation also occurs in auditory perception, this review proposes that perceived spatial separation-induced unmasking of target signals represents the essential function of the brain in untangling complex scenes. Typical examples of application of binocular unmasking in the industrial field are also provided in this review.
