TL;DR
提出了一种自我监督的框架,利用自然信号中的等变性来克服仅从压缩信号学习的难题,并成功地在多种成像问题上实现,包括稀疏视角X射线计算机断层扫描和自然图像修复
Abstract
In various imaging problems, we only have access to
compressed measurements
of the underlying signals, hindering most
learning-based strategies
which usually require pairs of signals and associated measurements f
