遥感图像变化检测因漏检成本高于误报而代价高昂。现有方法在提升精确率以降低误报成本方面仍受限,且难以聚焦目标变化,导致漏检和不连续问题。本文提出增强型卷积与Transformer混合网络(EHCTNet),通过增强特征学习能力并融合特征的频域成分,逐步提升召回率。首先采用双分支特征提取模块获取多尺度特征;其次利用改进模块I挖掘特征的频域成分;再通过基于科莫戈罗夫-阿诺德网络的增强标记挖掘模块提取语义信息;最后从改进模块II中挖掘有助于最终检测的语义变化信息的频域成分。大量实验验证了EHCTNet在理解复杂目标变化方面的有效性。可视化结果表明,相比当前最优模型,该方法能检测出更完整、连续的变化区域,并实现更准确的邻近区域区分。
原文摘要 · Abstract (English)
Remote sensing (RS) change detection incurs a high cost because of false negatives, which are more costly than false positives. Existing frameworks, struggling to improve the Precision metric to reduce the cost of false positive, still have limitations in focusing on the change of interest, which leads to missed detections and discontinuity issues. This work tackles these issues by enhancing feature learning capabilities and integrating the frequency components of feature information, with a strategy to incrementally boost the Recall value. We propose an enhanced hybrid of CNN and Transformer network (EHCTNet) for effectively mining the change information of interest. Firstly, a dual branch feature extraction module is used to extract the multi scale features of RS images. Secondly, the frequency component of these features is exploited by a refined module I. Thirdly, an enhanced token mining module based on the Kolmogorov Arnold Network is utilized to derive semantic information. Finally, the semantic change information's frequency component, beneficial for final detection, is mined from the refined module II. Extensive experiments validate the effectiveness of EHCTNet in comprehending complex changes of interest. The visualization outcomes show that EHCTNet detects more intact and continuous changed areas and perceives more accurate neighboring distinction than state of the art models.
