岩心外表面图像感兴趣区域提取算法设计

The Algorithm Design for Extracting Regions of Interests of Core Outer Surface

感兴趣区域提取在图像处理和分析领域有着重要地位。岩心外表面图像在采集的过程中常常带有无效区域,这些区域影响岩心外表面三维重建的视觉效果,因此需要从岩心外表面图像中提取感兴趣区域。实验表明,利用本文提出的岩心外表面感兴趣区域提取算法可以使岩心外表面三维重建的视觉效果更好。

The extraction technique of ROI plays an important role in image analysis. Usually, In the process of taking photograph of core surface image, some invalid regions are produced and these regions affect the visual effect of three-dimensional reconstruction of core outer surface. Therefore we need to extract ROI of core outer surface. The experiments results show that the ROI algorithm proposed by this paper is efficient and effective.
