【検証】pony系画像生成AIでのe621タグ使用
Added 2024-06-11 10:00:00 +0000 UTC1.はじめに
この記事では、PonyDiffusionV6XL及びその派生モデルで使用できると言われているe621タグの使用を試みています。
e621タグとは、ケモナー向け画像投稿サイト「e621」での画像分類タグになります。

結論から言えば、e621タグは明確に効いています。
これにより、Danbooruタグのみでは表現が難しいものも表現できるようになります。
例えば、「fingering partner」（パートナーへ行う指での行為）や「69 position」（シックスナイン）などがあります。
また、Danbooruタグとe621タグの両方を混ぜて使うこともできるようです。
そのため、Danbooruタグに慣れている方はDanbooruタグでプロンプトを組み、Danbooruタグでは表現が難しいポイントのみe621タグを探してみるようなアプローチも取れそうです。
このe621タグ使用の検証結果は、次の通りです。

4.解説
e621タグのプロンプトは、次の方法で作成できるようにしました。
①WebUI拡張機能「DominikDoom/a1111-sd-webui-tagcomplete」をインストールすることで、タグ入力の自動補完を有効にします。
https://github.com/DominikDoom/a1111-sd-webui-tagcomplete
②「Settings」タブで、自動補完用のデータファイルを「e621.csv」に変更して適用します。
③上記の設定で、e621タグでの自動補完が効くようになります。それをtxt2imgかimg2imgのプロンプト欄で確認します。
※効かない場合は、WebUIを再起動してみます。
④e621もDanbooruと同様にWikiでタグ解説ページがあるため、そのページで主要なタグの意味を確認します。
```
femboy
←男の娘
girly
←女の子っぽい
male/male
←男性同士
unretracted foreskin
←非割礼包茎
balls
←睾丸
```
⑤必要に応じて、Danbooruタグからe621タグへの変換を試してみます。

5.おわりに
お絵描き補助AIアプリ「AI-AssistantV2」で下絵を作り、新ControlNetモデル「CN-anytest」（現在はV3とV4が話題）でその下絵から意図する画像を生成したりと、興味深いワークフローが出てきています。

※「_pn」が名前に付いているモデルファイルが、pony系向け。「_am」はanimagine系向け。

そのようなワークフローを使ってみるにしても、プロンプトの重要性は引き続きあります。
地味ではありますが、小説家が語彙を増やすために辞書を読むように、Wikiのタグ解説ページを読んでみるのはいかがでしょうか。
あなたのセンスをより表現できている名作を期待しております。
