复值自组织映射(CSOM)实现了地雷可视化系统中塑料地雷和其他目标的自适应区分。然而,当电磁波测量的空间分辨率不够高时,这种区分有时会失败。为了解决这一问题,本文提出了两种增强可视化能力的技术。其一是SOM-空间拓扑在CSOM自适应分类中的应用。另一种是一种新的频域局部相关性特征提取方法。在实验结果中,我们发现这两种技术显著提高了可视化性能。局部相关方法也有助于减少CSOM分类中的调谐参数数量。
The complex-valued self-organizing map (CSOM) realizes an adaptive distinction between plastic landmines and other objects in landmine visualization systems. However, when the spatial resolution in electromagnetic-wave measurement is not sufficiently high, the distinction sometimes fails. To solve this problem, in this paper, we propose two techniques to enhance the visualization ability. One is the utilization of SOM-space topology in the CSOM adaptive classification. The other is a novel feature extraction method paying attention to local correlation in the frequency domain. In experimental results, we find that these two techniques significantly improve the visualization performance. The local-correlation method contributes also to the reduction of the number of tuning parameters in the CSOM classification.
