cigCK (Extended dataset)

This dataset is a supplementary part of the cigCK dataset, created by the Computational Interpretation Group (CIG) for the deep-learning-based simultaneous channel and karst interpretation in 3D seismic images.The main contributors are Jiarun Yang, Guangyu Wang, and Xinming Wu. Due to the 50 GB file size limitation of Zenodo, the cigCK dataset has been divided into two separate records. This record provides the additional portion of the dataset, which follows the same data format and content structure as the first part. Together, the two records form the complete cigCK dataset. Content description: The dataset contains additional synthetic 3D seismic volumes and their corresponding labeled volumes, each with dimensions of 500×500×250. In the label volumes, areas representing karsts are assigned a value of 1, channels are denoted with a value of 2, and all other regions are marked as 0. This supplementary dataset should be used in combination with the first part of the cigCK dataset to obtain the complete set of 200 pairs of seismic and label volumes.
