科学领域:

计算机视觉计算机视觉
图像处理图像处理
机器学习机器学习

背景情况:

非盲视图像解卷 (NBID) 旨在使用模糊内核从模糊和噪音版本恢复清晰的图像.
目前用于NBID的深度学习 (DL) 模型通常需要地面真相 (GT) 图像进行监督,这限制了它们在现实世界中的适用性,特别是在科学成像中.
核心的不准确性在训练和测试数据中都是常见的,这对解卷算法构成了重大挑战.

研究的目的:

为非盲视图像解卷 (NBID) 开发一种完全无监督的深度学习方法,不依赖于地面真相 (GT) 图像.
在一个端到端的培训框架内,有效地解决测量噪声和内核错误.
提高NBID方法在现实场景中的适用性,包括科学成像.

主要方法:

为NBID提出了一个无GT,端到端的深度学习培训过程.
引入了自我重建损失,以管理没有GT监督的测量噪声.
一个自我集合损失函数和集合推理方案,结合相守内核扰动,用于处理内核错误.
在损失函数中集成了一个转移机制,以解决由内核错误引起的转移模两可.

主要成果:

拟议的无监督NBID方法与现有的无监督方法相比,显示出更高的性能.
与最近的监督NBID技术相比,该方法取得了具有竞争力的结果.
该方法有效地处理测量噪声和内核不准确性,而不需要基准真实数据.

结论:

开发的完全无监督的DL方法为NBID提供了可行的解决方案,克服了依赖GT的方法的局限性.
建议的处理噪声和内核错误的技术是有效的,在实际环境中实现了强大的图像解卷.
这项工作推进了无监督图像解卷的领域,扩大了其在科学和其他成像领域的潜在应用.
