Seismic data reconstruction via an adaptive feature fusion network

Seismic data reconstruction is a crucial step in seismic data processing. Traditional methods and deep learning approaches have both been widely used in this field. However, they ignored the interactive learning of inter-channel information, especially in the case of high missing rate where feature extraction became more difficult. To address this issue, we propose an adaptive feature fusion network for the reconstruction of both random and consecutive missing seismic data. The information interaction block is designed into this model to improve the efficiency and adaptability of feature selection. It adaptively emphasizes important feature channels and enables inter-channel information exchange learning. To enhance the ability to capture global and local details, a cross-dimensional feature fusion module is designed at the bottleneck, integrating information from both the channel and spatial dimensions. Additionally, the strategy loss is designed to enable the network to learn the correlations among missing parts of the seismic traces, thereby boosting the reconstruction performance of our model. Compared with other state-of-the-art seismic data reconstruction methods, the proposed algorithm achieves improvements in both qualitative and quantitative evaluations: the reconstruction quality has improved by 20% on both synthetic and field datasets with random missing data. The reconstruction quality has improved by 30% on both synthetic and field datasets with consecutive missing data. At the end of the paper, we conducted ablation experiments, hyperparameter analysis and discussion. • A novel information interaction block is designed to enable inter-channel information exchange learning and improve the efficiency and adaptability of feature selection. • The cross-dimensional feature fusion module is designed to extract features from both channel and spatial dimensions to enhance the ability to capture global and local details. • This paper innovatively designs a loss function called strategy loss, which guides the network to learn the missing parts of the seismic traces, thereby enhancing the reconstruction performance of our model.
