    基于视觉双驱动认知的高分辨率遥感影像自学习分割方法

    Self-learning segmentation of high-resolution remote sensing images based on visual dual-drive cognition

    • 摘要: 针对当前高分辨率遥感影像场景复杂难以简单解析,且变化多样难以从样本库获取准确参考的问题,文章参照视觉的双驱动认知机理,提出了一种自学习的高分辨率遥感影像分割方法。该方法在借鉴视觉感知原理的基础上,通过非监督的自适应分析解读场景中的典型地物,并结合神经网络实现典型地物的自学习辨识,最后结合非监督分析与神经网络学习实施分割结果的自检校修正。采用包含复杂地面场景的真实高分辨率遥感影像数据,对比2种目前流行的深度神经网络分割方法Mask R-CNN (mask region-based convolutional neural network,MR)和ScalableViT (scalable vision Transformers,SViT)进行实验,实验结果表明所提方法能保持稳健、可靠的分割精度,在地物认知、泛化性能和抗干扰能力方面具有显著优势,是一种性价比高、实用性强的方法。

       

      Abstract: The current high-resolution remote sensing images involve complex scenes that are difficult to analyze. Meanwhile,owing to the diverse scenes,there is a lack of accurate reference obtained from the sample database. Therefore,this paper proposed a self-learning segmentation method for high-resolution remote sensing images,with reference to the visual dual-drive cognition mechanism. Based on the principle of visual perception,this method interpreted the typical ground objects in the scene through unsupervised adaptive analysis. In addition,it achieved self-learning identification of typical ground objects by integrating a neural network. Finally,the segmentation results were self-checked and corrected by combining unsupervised analysis and neural network learning. Using real high-resolution remote sensing image data containing complex ground scenes,the comparative experiments were conducted between the proposed method and two popular deep neural network segmentation methods:mask region-based convolutional neural network (Mask R-CNN) and scalable vision transformer (ScalableViT). The results showed that the proposed method can maintain robust and reliable segmentation accuracy,and outperformed others in terms of ground object cognition,generalization performance,and anti-interference ability. As such,it proved to be a cost-effective and practical approach.
