Research title: Enhancing Building Footprint Extraction Accuracy Using Single-Image Super-Resolution Building Datasets

Research Summary

My research mainly focuses on using deep learning methods for building rooftop dection and super-resolution. In the recent one year, I was exploring methods to enhance building rooftop extraction accuracy with Single-Image Super-Resolution(SISR) on building datasets. My current research focuses on deep learning methods to detect damaged buildings in the war-related areas, as well as super-resolution approaches.

All topics of my research are related to the deep learning applications for assisting urban management, environmental monitoring, emergency response, and other land use management issues. By enhancing the performances with the deep learning-based methods, the increased detection accuracy can help the governments and the companies to obtain accurate results.
