一种光学影像和SAR影像的一体化分割配准方法,包括步骤:步骤1,对光学影像和SAR影像预处理;步骤2,对光学影像和SAR影像,分别随机产生聚类中心并利用模糊C均值聚类算法进行初始分割,得到初始的区域;步骤3,对光学影像和SAR影像分别进行多层水平集分割,得到面分割结果;步骤4,进行sift算法配准,然后判断是否存在同名点,是则将...
Why Huawei Optical Transmission? Ultra-Large Bandwidth High-performance 100G - 800G, single fiber capacity 96T, optical and electrical in one platform, flexible in board dimensions, and smooth evolution to 1T/2T. Simplified O&M Real-time monitoring and intelligent diagnostics on the network at ev...
Here, we use Sentinel-1 SAR interferometry to produce a map of the ground velocities in the area of the Mw 7.5 earthquake for the seven months following the 2018 earthquake. We show evidence of surface deformation along the western coast of the Palu bay, indicating that the Palu Koro off...
from optical images. As a large open SAR-optical dataset with multiple scenes of a high resolution, we believe QXS-SAROPT will be of potential value for further research in SAR-optical data fusion technology based on deep learning. The QXS-SAROPT Dataset for Deep Learning in SAR-Optical ...
The high-resolution optical and synthetic aperture radar (SAR) images are widely used in many remote sensing application areas such as image fusion and change detection where image registration is a ...
Deep learning Synthetic Aperture Radar (SAR) Optical imagery 1. Introduction Two of the most used modalities for space-borne remote sensing are Synthetic Aperture Radar (SAR) and optical imagery, since the information they provide about observed scenes is highly complementary. Thus SAR-optical data ...
Although Convolutional Neural Networks (CNNs) have significantly improved the development of image Super-Resolution (SR) technology in recent years, the existing SR methods for SAR image with large scale factors have rarely been studied due to technical difficulty. A more efficient method is to obta...
Synthetic aperture radar (SAR) and optical sensing are different earth observation methods. Compared to the optical sensors, the SAR has the imaging advantages such as all-weather, all-time, ability to traverse clouds and vegetation, etc. We propose the application of the cycle-consistent generativ...
Aiming at improving the performance of scale invariant feature transform (SIFT) algorithm during the registration of optical and synthetic aperture radar (SAR) images, a new SIFT algorithm is proposed. Firstly, the nonlinear diffusion scale space of optical and SAR images is constructed by using non...
