The development of an efficient and robust method for dense image-matching has been a technical challenge due to high variations in illumination and ground features of aerial images of large areas. In this study, I propose a method for the dense matching of aerial images using an optical flow field and a fast-guided filter which is beneficial for automatic DSM/DEM generation.

Building detection is a fundamental and significant task that aims to locate all buildings in the remote sensing image. It can be an upstream task in various applications, such as urban planning, environment monitoring, and land resource utilization. I proposed  a combined CNN and transformer hybrid neural network for precision building detection from high-resolution remote sensing images which can be utilized in urban change monitoring and disaster assesment.

Aerial/Satellite image based specific feature extraction is crucial to a lot of applications such as autonomous driving, urban planning, and disaster assesment. However most of exsiting studies are focusing on pixel-level based segmentation, which are inadequate for practical applictions. In this study we propose CNN and Transformer based neural networks for automatic man-made infrastructures extraction and vectorization.
