One-class Damage Detector Using Deeper Fully-Convolutional Data Descriptions for Civil Application

no code implementations3 Mar 2023 Takato Yasuno, Masahiro Okano, Junichiro Fujii

Furthermore, we propose a valuable solution of deeper FCDDs focusing on other powerful backbones to improve the performance of damage detection and implement ablation studies on disaster datasets.

MN-Pair Contrastive Damage Representation and Clustering for Prognostic Explanation

no code implementations15 Jan 2023 Takato Yasuno, Masahiro Okano, Junichiro Fujii

For infrastructure inspections, damage representation does not constantly match the predefined classes of damage grade, resulting in detailed clusters of unseen damages or more complex clusters from overlapped space between two grades.

River Surface Patch-wise Detector Using Mixture Augmentation for Scum-cover-index

no code implementations13 Jul 2022 Takato Yasuno, Junichiro Fujii, Masazumi Amakata

We propose a patch-wise classification pipeline to detect scum features on the river surface using mixture image augmentation to increase the diversity between the scum floating on the river and the entangled background on the river surface reflected by nearby structures like buildings, bridges, poles, and barriers.
