让卫星图像超分辨率更实用,直接服务于自动化分析任务。

Toward task-driven satellite image super-resolution

  • 基于任务驱动设计超分辨率方法,提升重建结果可用性。
  • 通过下游视觉任务表现评估超分质量,避免主观感知偏差。
  • 为真实场景超分提供可落地的评估与训练框架,适合遥感应用者。

超分辨率旨在从低分辨率观测中重建高分辨率图像。当前基于深度学习的先进方法能生成感知质量高的图像,但其重建细节是否接近真实地面真值,以及能否为图像分析算法提供有效信息仍不明确。本文聚焦于后者,提出一种面向任务驱动的超分辨率学习方法,使重建结果更适合自动化图像分析。在初步研究中,我们提出了一个评估现有计算机视觉任务是否适用于超分辨率算法评价与训练的方法论,并通过实验验证了其有效性。该工作有望为选择合适的计算机视觉任务奠定基础,从而推动真实世界超分辨率技术的发展。

原文摘要 · Abstract (English)

Super-resolution is aimed at reconstructing high-resolution images from low-resolution observations. State-of-the-art approaches underpinned with deep learning allow for obtaining outstanding results, generating images of high perceptual quality. However, it often remains unclear whether the reconstructed details are close to the actual ground-truth information and whether they constitute a more valuable source for image analysis algorithms. In the reported work, we address the latter problem, and we present our efforts toward learning super-resolution algorithms in a task-driven way to make them suitable for generating high-resolution images that can be exploited for automated image analysis. In the reported initial research, we propose a methodological approach for assessing the existing models that perform computer vision tasks in terms of whether they can be used for evaluating super-resolution reconstruction algorithms, as well as training them in a task-driven way. We support our analysis with experimental study and we expect it to establish a solid foundation for selecting appropriate computer vision tasks that will advance the capabilities of real-world super-resolution.
