Abstract

Hyperspectral Imagery (HSI) has great importance in industrial remote sensing applications, such as geological exploration and soil mapping. HSI has high spectral resolution, which gives each object a unique spectral response, making them easily identifiable. Nonetheless, their spatial resolution is compromised due to sensor limitation, which hinders utilizing HSI to their full potential. This paper deals with the spatial enhancement of HSI using Single Image Super Resolution (SISR) approaches. One of the main challenges in this area of research is preserving the spectral signature of HSI while improving the spatial resolution simultaneously. To tackle this challenge, we propose a 3D Wide Residual Convolutional Neural Network (3D-WRCNN) model that effectively utilizes the principle of wide activation to enhance feature propagation throughout the network. Residual connections are also deployed to boost image reconstruction and information sharing between the layers to reduce overfitting. Furthermore, this study incorporates and demonstrates the usage of Bayesian-optimized hybrid loss function to further improve the performance of the 3D-WRCNN. The quantitative and qualitative evaluation indicate that the proposed approach prevails over other state-of-the-art approaches. The implementation of the proposed model is provided in this repository: https://github.com/NourO93/SISR_Library
