而Non-local中运用的self-attention建模的是像素之间的二阶关系。具体来说，Non-local中通过计算query和k...
We propose a self-supervised cross-scale nonlocal attention network for blind SR (CNSR) which jointly models a blur kernel estimation module (KEM) based on a regularization model and a high-resolution image reconstruction module (HRM) based on a deep neural network. The low-resolution (LR) ...
