第二张图芯片的那个是怎么跑出来的?我跑不下来这个效果 #111
Comments
sd没法生成文字的原因在于vae的八倍下采样,所以小文字没法生成,但是大文字一直是可以的。图里的文字是因为文字本身够大 |
第二张芯片图对应的upscale是4。 |
是的,小文字目前没办法修复。一个可能的办法是把文字区域检测出来放大之后再修复,不过现在还没有做过测试~ |
请问这是什么意思啊,VAE encoder是下采样导致小文字原本的信息损失了嘛。那为什么小的纹理特征可以恢复,单纯文字不行呢? |
我用的参数是 python -u inference.py --version v2 --task sr --upscale 2 --cfg_scale 4.0 --input inputs/wkkimg --output results/wkkimg --device cuda
顺便再问一下,芯片图里的字能完美清晰化,是不是说这个方法能放大文字了?
