想请问作者,IR-SDE在反向扩散过程中,起点是LQ还是纯噪声呢?我有看通常的做法是从噪声出发,然后LQ作为条件加入,这两种的做法理论区别是什么呢

你好,IR-SDE起点是LQ加上噪声。这两种做法都可以,不过LQ作为条件直接加的话比较生硬,具体可以看下我们这篇综述论文哈:Taming Diffusion Models for Image Restoration: A Review.
Sorry, something went wrong.
好的,IR-SDE就是完全的高斯噪声+LQ图像作为扩散起点,然后中间的条件只有时间?
是的。但在implement时发现加入LQ image作为条件效果会更好。
