Location: Report hall of Yifu
Abstract:
In systems of remote sensing image monitoring the quality of automatic classification of objects is largely dependent on the results of object detection. The real images subject to distortions caused by the presence of shadows, changing lighting conditions and scenes of their own imaging equipment noise. The presentation will show the developed technologies for remote sensing image processing, object and change detection and map updating. Next, we will introduce the effective tool developed for object detection, change detection, and updating digital maps through remote sensing images. We will demonstrate and explain the two application scenarios of this tool for detecting discrete objects (buildings, ships), slender objects (roads), and detecting changes in images taken at different times. To detect objects at UAV (super-high resolution - 0.1–0.3 m) images, we developed an approach based on the proposed deep neural network architecture integrating the Faster R-CNN with the Feature Pyramid Network module. We proposed an algorithm to detect shadows on the base of definition of its structure and features on urban or built-up satellite images by using neural networks. The results of object detection will be shown. Finally, the practical experience in creating a comprehensive processing system for remote sensing and map images, as well as the future application scenarios of the developed technology, will be discussed.
