In this paper, we review diminished reality (DR) studies that visually remove, hide, and see through real objects from the real world. We systematically analyze and classify publications and present a technology map as a reference for future research. We also discuss future directions, including multimodal diminished reality. We believe that this paper will be useful mainly for students who are interested in DR, beginning DR researchers, and teachers who introduce DR in their classes.

减弱现实的调查：视觉隐藏，消除和透视真实物体的技术

在本文中，我们回顾了缩小现实（DR）研究，这些研究从视觉上移除，隐藏和查看了真实世界中的真实对象。我们对出版物进行系统地分析和分类，并提供技术图，以供将来研究参考。我们还将讨论未来的方向，包括多模式现实减弱。我们认为，本文主要对感兴趣的学生，入门的DR研究人员以及在课程中介绍DR的老师有用。
