4x-Ultrasharp四倍分辨率Upscaler

使用介绍

4x-Ultrasharp是基于超分辨率原理的算法，通过预处理、低分辨率图像生成、特征提取、高分辨率图像生成、图像重建和后处理等步骤，将图像分辨率提升4倍，增强清晰度和细节，同时减少噪点和模糊。一般在纠结用哪种算法放大图片时，无脑选这个算法，照片级别的。

如何安装：

将文件重命名为：

4x-UltraSharp.pt至：4x-UltraSharp.pth

将文件4x-UltraSharp.pth 复制到文件夹内：“\ YOUR ~ STABLE ~ DIFFUSION ~ FOLDER\models\ESRGAN\”）

重新启动Stable Diffusion

现在在“Extra Tab”中你得到了新的upscaler
