【Stable Diffusion】少女の1日の生活

Stable Diffusionで再現できる服装や行動、シチュエーションは本当にたくさんあります。
今回は、1日の生活を密着する形でどこまで表現できるか試してみます。
少女が朝起きてから夜寝るまで。

最後に使用したプロンプトもまとめておきます。

1日の生活

寝起き

朝の陽ざしで目を覚ました少女。朝から元気そうです。

顔を洗う

洗顔。「顔を洗っている瞬間」のイラストや写真はあまりなさそうですし、いまいち再現できていません。

歯を磨く

ポージングなどは良い感じですが、歯ブラシは上手く生成できませんでした。

支度する

着替えて髪を結びました。シンプルな姿見にしたかったんですが、やたら豪華なドレッサーになってました。このあたりはモデルデータによって生成されるものが変わりそうな気がします。

朝食

朝ごはん。美味しそうな何かを食べてますけど、よくよく見ると何を食べてるのか謎です。
食器など、細かい描写も上手くいきにくい印象です。

登校

背景は通学路（school route）を指定しました。良い感じの歩道を生成してくれるのでけっこう好きなプロンプトです。
さっきから制服や髪型が微妙に違ってるのはご愛敬（ばっちり合わせるならcontrol netまたはloraを使った方が良さそうです）

授業

授業が難しくてしかめっ面になってる少女。
教科書やノートの、それっぽい文字みたいなものは手書きよりAIの方が得意なところです。手書きでこの「何が書いてあるかは読めないけど文章が書いてあることはわかる状態」を作るのは本当に難しいです。

昼食

ランチタイム。楽しいひと時。
「お弁当」って日本独特の文化らしくて、「eating lunch」だけだと普通にお皿に盛りつけられた料理が生成されます。ここでは「bento」を加えて生成しました。

下校

放課後になって、うきうきと歩いてる少女。
登校シーンもそうですが、なぜか鞄は2つ生成されやすいです。なぜ。

バイト

コンビニでバイトする少女。
先ほどの教科書の話と似たところで、商品棚もAIが強いです。ただ、実在の商品と似通ったものを確実に排除できたら最高なんですけど、今のところは人の目で確認が必要になります。

帰路

バイトを終えて帰路につく少女。
夜も更けてきました。

着替える

帰宅したので部屋着に着替えます。
着替えはどうあがいてもちょっとえっちな感じになりますね。しかたないですね。

夕食

家族と晩御飯。
食べてるものがなんとなく朝ごはんのイメージなんですけど、肉っぽいものもあるしまあよし。

風呂

お風呂に浸かって1日の疲れを洗い流します。
bubbleとかsoapとかを入れるとお風呂に入ってる感が増します。けどヘアゴムまで泡になってます。

着替える

パジャマに着替えて寝る準備万端。

雑誌を読む

寝る前にちょっとだけ雑誌を読もう、と思ってたけど眠気が襲ってきてうつらうつらしてる少女。

寝る

夢の中へ。

まとめ

少女の1日の生活は以上です。
プロンプトやネガティブプロンプトの基本設定にばらつきがあるのは、ひとつ前の外見に合わせるため、または生成時に余分なものが生まれたときにそれを消すためです。
（たとえば、ちびキャラが生成されてしまった時にはネガティブプロンプトにchibiを入れてます）

流れを追ったイラストを作ってみた結論としては、

・細かい道具を使用するシチュエーションは再現が難しい。Loraがあればそれを使った方がよさそう。

・細部の描写を共通にするのはかなり難しい。実現するにはLoraを使ったりCheckpointを吟味する必要がありそう。

・ダミーテキストやダミー商品はAIのお手の物。ただ、商品などは実在のものと似通ったものがないか確認する必要はある。

・ひたすらかわいい。

このあたりです。
生成系AIのキャラの描写が苦手、可愛くない、っていう方もいるらしいですが、個人的にはめちゃくちゃ可愛いと感じてます。

今回は日常的なシーンでしたが、どうせならAIだからこその、手描きでは再現が難しいものを作れたらいいなと思っています。
またどこかのタイミングで一連の流れをまとめます。
