中文摘要: |
基于Radarsat-1数据提出了一种集成Gibbs采样标记步骤的北极海冰SAR图像分割算法,该算法综合考虑了斑点噪声、纹理特征等不确定因素,经由像素到区域再到大尺度区域这一途径,把区域化标识、Gibbs采样标记以及区域合并等操作组合起来,实现对海冰SAR图像的分割,针对S.Laurence Bay和Beaufort海冰图像的测试实验表明,与基于区域的MRF分割算法相比提出的算法可有效提高图像分割的准确性。 |
英文摘要: |
Based on Radarsat-1 data, the authors propose a SAR image segmentation algorithm for Arctic sea ice that integrates Gibbs sampling steps. This method considers the uncertainties of speckle noise and texture features, and combines the regionalization mark, Gibbs sampling,and region merging together via pixel, region and larger-scale region. It successfully segmented the SAR image of Arctic sea ice. Experiments on S. Laurence Bay and Beaufort sea ice images show that the proposed method can effectively improve the segmentation accuracy, compared with the region-based MRF algorithm. |
