Python?DPED機(jī)器學(xué)習(xí)之實(shí)現(xiàn)照片美化

更新時(shí)間：2021年11月29日 08:47:41 作者：劍客阿良_ALiang

本篇文章主要介紹了利用Python中的DPED工具實(shí)現(xiàn)照片一鍵美化，可以實(shí)現(xiàn)照片亮度提高和色彩鮮明度提高，代碼簡潔易懂，具有一定學(xué)習(xí)價(jià)值，感興趣的小伙伴可以了解一下

前言

最近發(fā)現(xiàn)了一個(gè)可以把照片美化的項(xiàng)目，自己玩了玩，挺有意思的，分享一下。

Github地址：DPED項(xiàng)目地址

下面來看看項(xiàng)目怎么玩？先放一些項(xiàng)目給出的效果圖?？梢钥闯稣掌髁梁每戳恕?/span>

環(huán)境部署

項(xiàng)目結(jié)構(gòu)

下面是項(xiàng)目的原始結(jié)構(gòu)：

tensorflow安裝

按照項(xiàng)目的說明，我們需要安裝tensorflow以及一些必要的庫。

如果安裝gpu版本的tensorflow需要對照一下

tensorflow官方對照地址：TensorFlow官方CUDA版本對照

我的cuda是11.1的版本，按照tensorflow后還是缺少部分dll，如果有相同問題的，可以用我提供的資源包? 提取碼：TUAN。

缺少哪個(gè)dll，直接復(fù)制到你的NVIDIA GPU Computing Toolkit目錄對應(yīng)cuda的bin目錄下。

按照自己的版本來，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

其他依賴安裝

Pillow, scipy, numpy, imageio安裝

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下載

因?yàn)槟Ｐ臀募?，github的項(xiàng)目中無法上傳這么大的文件，作者讓我們自己下。

我把DPED的資源包統(tǒng)一打包了，也可以從我的云盤下載，放到項(xiàng)目的vgg_pretrained目錄下。下圖是資源包的目錄

資源包地址? 提取碼：TUAN。

項(xiàng)目運(yùn)行

項(xiàng)目需要的環(huán)境我們都裝好了，我們跳過訓(xùn)練的部分，測試model的方法官方給出了命令。

準(zhǔn)備圖片素材

我準(zhǔn)備了幾張圖，就不全展示了，展示其中的一張。

按照項(xiàng)目的要求，需要放在對應(yīng)的目錄下。

測試效果

執(zhí)行命令

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