如何提升清晰度 #38
Comments
能够提供一下需要画质增强的电影的一帧和相应的复原帧吗?目前我能给出的建议是,1.我训练的退化可能没有你电影的退化严重,可以加大训练的退化力度进行finetune 2.或者用4x超分,然后载下采样回去,我觉得也能比1x的清晰度更高 |
你用的是什么模型,是否用了Real world SR模型,用的是其中的GAN模型还是基于L1损失的模型 |
1:用的real world SR模型 2:两个阶段的模型都重训练了 当前是非GAN的方式,GAN方式还在训练中。 |
非GAN的图像增强模型确实会比较平滑,是正常现象,基于GAN的会更清晰。 |
好 谢谢啦 |

我想把该算法用在电影的画质增强上,目前模型输出图片的稳定性已经可以了,就是清晰度总觉得不够,有种朦胧的画面感,不知道有没有参数可以改善当前现状,我也在尝试用GAN方式进行训练,感觉对清晰度提升也不明显
