Pyramidal Image Segmentation Based on U-Net for Automatic Multiscale Crater Extraction

Abstract: To extract craters with a radius greater than 10 km more effectively from lunar digital elevation maps, pyramidal image segmentation based on the U-Net model is proposed, and the conversion relationship between the multilayer image pyramid and the geographic coordinates of the crater is established. The crater image pyramid method ensures the full coverage of the study area with a small number of images and that each crater exists in several images with different resolutions. The proposed method can effectivel… Show more

“…Therefore, many scholars applied deep learning methods to change detection tasks and achieved satisfactory results because deep learning has significantly better generalization abilities than traditional methods. (7,8) During the last few years, many neural networks have emerged and have been applied to the challenge of the detection of changes in images by remote sensing; convolutional neural networks (CNNs) are the most commonly used. Especially with the development of a fully convolutional network (FCN) that has the ability to make dense predictions, FCN and its adaptations soon became suitable choices for the task of change detection.…”
