This repo contains two files: crack detection dataset (weakly_sup_crackdet_dataset.zip), and pretrained TensorFlow model for Xception65 (pascal_voc_seg.zip). The dataset consists of rough annotations used in weakly-supervised crack detection. It contains roughly annotated ground truths for the following datasets: Aigle Crack Forest Dataset DeepCrack Annotations of different "roughness" are stored. Directories suffixed "*_dil*" are synthetically-generated annotations, while directories suffixed "*_rough" and "*_rougher" are manually-generated annotations. The detail of the dataset is described in [1]. Please also refer to our GitHub repo https://github.com/hitachi-rd-cv/weakly-sup-crackdet for more details. This dataset is made available by Hitachi, Ltd. The pretrained model is used by [1]. Please use it for comparison experiments. Please refer to our GitHub repor for more details.
