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： https://pan.baidu.com/s/1IUm8xz5dhh8iW_bLWfihPQ 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： https://pan.baidu.com/s/1IUm8xz5dhh8iW_bLWfihPQ 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

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。
总结
项目整体没什么毛病，只是如果要单独处理一张图片还需要对项目魔改一下。我下一篇文章会稍微魔改一下，简化项目结构，处理单张图片。
