Observation-based diminished reality: a systematic literature review

Diminished reality (DR) is a set of techniques for visually removing unwanted objects within an environment in real time. This study attempts to carry out a systematic literature review to investigate the potential benefits, challenges, and efficacy of DR in various applications. To investigate the relevant studies, a classification framework with six aspects, namely, paper type, DR type, processing workflow, background data type, display device type, and DR environment, is provided. The relevant papers were mainly sourced from the Scopus academic database. From an initial number of 1284 papers published from 2000 to 2024, 67 were selected as key articles for analysis. Based on the findings, this study offers recommendations for implementing observation-based DR-supported functionality for AR applications going forward.
