摘要
目前主流的神经网络在面对复杂多样的地物目标时难以精确区分,同时样本数量少、弱监督条件也容易为神经网络带来大量噪声与错误.为此,在分析遥感影像的地物特点后,提出一种基于权重动态变形的双重网络遥感影像分类方法,通过构架灵活、简易却有效的权重动态变形结构,构建经过改进的分类网络与目标识别网络,形成双网络对照的自我验证,从而提高学习性能、修复误差、增补遗漏、提高分类精度.实验结果表明,所提方法在容易实施的基础上,表现出更强的地物认知能力和更强的噪声抵抗能力,即其能够适应各种遥感影像的分类任务,具有较为广阔的应用潜力.
Abstract
Currently,popular neural networks not only struggle to accurately recognize various types of surface targets but also tend to introduce significant noise and errors when handling limited samples and weak supervision.Therefore,this study proposes a dual-network remote sensing image classification method based on dynamic weight deformation,after analyzing the features of remote sensing images.By constructing a flexible,simple,and effective weight dynamic deformation structure,we establish an improved classification network and target recognition network.This introduces the self-verification ability of dual network comparison,thereby enhancing learning performance,error correction,recognition efficiency,supplementing omissions,and improving classification accuracy.Experimental comparisons show that the proposed method is easy to implement and exhibits stronger cognitive ability and noise resistance.It confirms the adaptability of the proposed method to various remote sensing image classification tasks and its vast application potential.
