Semantic segmentation of high-resolution satellite images using deep learning

The increasing common use of incidental unrectified satellite images have many applications for mapping of earth for coastal and ocean applications. Hazard assessment and natural resource management can also be done via this process. Remote sensing is being used extensively due to the increase in the number of satellites in space. It is also the future of optimization of GPS systems and the internet. To demonstrate the semantic segmentation process, this study presents proposed solutions along with their evaluation metrics adapted from fully connected neural networks such as UNet and PSPNet. UNet architecture based deep learning model has outperformed PSPNet based architecture with overall Mean-IOU score of 0.51 on the test set in the semantic segmentation. The overall accuracy of the model can further be improved by providing homogeneous features to train the model, balance classes and by incorporating more data set for semantic segmentation. The developed model can be useful to the authorities for smart city planning and landuse mapping.
