前言

最近发现了一个可以把照片美化的项目，自己玩了玩，挺有意思的，分享一下。

Github地址：DPED项目地址

下面来看看项目怎么玩？先放一些项目给出的效果图。可以看出照片更明亮好看了。

环境部署

项目结构

下面是项目的原始结构：

tensorflow安装

按照项目的说明，我们需要安装tensorflow以及一些必要的库。

如果安装gpu版本的tensorflow需要对照一下

tensorflow官方对照地址：TensorFlow官方CUDA版本对照

我的cuda是11.1的版本，按照tensorflow后还是缺少部分dll，如果有相同问题的，可以用我提供的资源包  提取码：TUAN。

缺少哪个dll，直接复制到你的NVIDIA GPU Computing Toolkit目录对应cuda的bin目录下。

按照自己的版本来，我的tensorflow命令如下：

pip install tensorflow-gpu==2.4.2 -i https://pypi.douban.com/simple
pip install tf-nightly -i https://pypi.douban.com/simple

其他依赖安装

Pillow, scipy, numpy, imageio安装

pip install Pillow -i https://pypi.douban.com/simple
pip install scipy -i https://pypi.douban.com/simple
pip install numpy -i https://pypi.douban.com/simple
pip install imageio -i https://pypi.douban.com/simple

VGG-19下载

因为模型文件太大，github的项目中无法上传这么大的文件，作者让我们自己下。

我把DPED的资源包统一打包了，也可以从我的云盘下载， 放到项目的vgg_pretrained目录下。下图是资源包的目录

资源包地址  提取码：TUAN。

项目运行

项目需要的环境我们都装好了，我们跳过训练的部分，测试model的方法官方给出了命令。

准备图片素材

我准备了几张图，就不全展示了，展示其中的一张。

按照项目的要求，需要放在对应的目录下。

测试效果

执行命令

python test_model.py model=iphone_orig test_subset=full resolution=orig use_gpu=true

执行过程

项目会生成前后对比图以及最终结果图。

前后效果图，左边为原始图，右边为对比图。

结果图如下

可以明显的看出，新图已经明亮了许多，色彩也变的比较鲜明了，效果还是很不错的。
