# 动漫视频模型比较

[English](anime_comparisons.md) **|** [简体中文](anime_comparisons_CN.md)

## 更新

- 2022/04/24: 发布 **AnimeVideo-v3**. 主要做了以下更新：
  - **更自然**
  - **更少瑕疵**
  - **颜色保持得更好**
  - **更好的纹理恢复**
  - **虚化背景处理**

## 比较

我们将 RealESRGAN-AnimeVideo-v3 与以下方法进行了比较。我们的 RealESRGAN-AnimeVideo-v3 可以以更快的推理速度获得更好的结果。

- [waifu2x](https://github.com/nihui/waifu2x-ncnn-vulkan). 超参数: `tile=0`, `noiselevel=2`
- [Real-CUGAN](https://github.com/bilibili/ailab/tree/main/Real-CUGAN): 我们使用了[20220227](https://github.com/bilibili/ailab/releases/tag/Real-CUGAN-add-faster-low-memory-mode)版本, 超参: `cache_mode=0`, `tile=0`, `alpha=1`.
- 我们的 RealESRGAN-AnimeVideo-v3

## 结果

您可能需要**放大**以比较详细信息, 或者**单击图像**以查看完整尺寸。 请注意下面表格的图片是从原图里裁剪patch并且resize后的结果，您可以从
