The features of tunnels hinder distinguishing in-focus photographs taken in tunnels. Focused tunnel images are required for extracting meaningful information about tunnels such as cracks. In this paper, we propose a new focus algorithm induced by commonly used algorithms and suggest a pre-processing phase. The effectiveness of the suggestion is proven by the experimental results from actual tunnel images. © 2020 ICIC International.
