###こんにちは、みんな。
今日も引き続き、興味深い AI プロジェクトを皆さんと共有していきます。 前回は、GAN (敵対的生成ネットワーク)を使用して静止画像を動かす を共有しました。
今日は、NoGAN の画像強化テクノロジーを使用して古い写真をカラー化する方法を共有します。効果は次のとおりです。 元の画像 着色後NoGAN は新しいものです。 GAN のタイプでは、GAN のトレーニングにかかる時間が最も短くなります。 今日共有するプロジェクトはすでに GitHub 上のオープンソース プロジェクトです。実行してみましょう。 1. 準備まず、git clone コマンドを使用してソースコードをダウンロードします。git clone https<span style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">:</span><span style="color: rgb(215, 58, 73); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">//</span>github<span style="color: rgb(0, 92, 197); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">.com</span><span style="color: rgb(215, 58, 73); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">/</span>jantic<span style="color: rgb(215, 58, 73); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">/</span>DeOldify<span style="color: rgb(0, 92, 197); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">.git</span>
