【StableDiffusion】同じ人物で違う服・ポーズにしたい！Seed（シード）を使ってみた

こんにちは。アメリカ・シリコンバレー在住のSeikaです。

現在、StableDiffusionを使って、同じ人物で違う服・ポーズにすることを試みています。
調べているとSeed（シード）という言葉が出てきました。
そこで今回はSeed値を使って生成した画像を比較していきたいと思います！

失敗作も多いのですが過程を残すのも大事だと思いますので、noteにまとめています。ご了承ください。

（2024年4月10日公開）

Seed(シード)値の固定とは？

Stable Diffusionでは、Seed値と呼ばれるランダムな数値を使用して画像を生成します。
Seed値を固定することで、同じ人物の画像を複数生成することができます。

Seed値の固定方法

Stable DiffusionのWebUIで、"Generation"タブを開く。
"Seed"欄を確認
デフォルトはランダムになるよう-1になっています。
ここに任意のSeed値を入力。
"Generate"ボタンをクリックして、画像を生成。
先ほどの任意で指定したSeed値を入力、別のプロンプトで生成。

Seed値1

まずSeed値1を入力してみます。

Top quality, 1 beautiful woman, long Hair, brown hair, wearing Camisole & skirt, shy-smile, Sunlight, at street, 35mm Lens, /1, (white Background: 1.3) <lora:ip-adapter-faceid-plusv2_sd15_lora:1>

Negative prompt: sfw ng:deepnegatives:v.1.7.5t, ((badhandv4)), (worst quality:2), (low quality:2), (normal quality:2), lowres, bad anatomy, bad hands, normal quality, ((monochrome)), watermark

Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 1, Size: 512x512, Model hash: 1a17bcd93d, Model: beautifulRealistic_v7, ControlNet 0: "Module: none, Model: None, Weight: 2, Resize Mode: Crop and Resize, Low Vram: False, Guidance Start: 0, Guidance End: 1, Pixel Perfect: True, Control Mode: Balanced, Hr Option: Both, Save Detected Map: True", Lora hashes: "ip-adapter-faceid-plusv2_sd15_lora: a95a0f4bdcb9", Version: v1.8.0

Seed値5

今度は適当に５。

Top quality, 1 beautiful woman, long Hair, brown hair, wearing Camisole & skirt, shy-smile, Sunlight, at street, 35mm Lens, /1, (white Background: 1.3) <lora:ip-adapter-faceid-plusv2_sd15_lora:1>

Negative prompt: sfw ng:deepnegatives:v.1.7.5t, ((badhandv4)), (worst quality:2), (low quality:2), (normal quality:2), lowres, bad anatomy, bad hands, normal quality, ((monochrome)), watermark

Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 5, Size: 512x512, Model hash: 1a17bcd93d, Model: beautifulRealistic_v7, ControlNet 0: "Module: none, Model: None, Weight: 2, Resize Mode: Crop and Resize, Low Vram: False, Guidance Start: 0, Guidance End: 1, Pixel Perfect: True, Control Mode: Balanced, Hr Option: Both, Save Detected Map: True", Lora hashes: "ip-adapter-faceid-plusv2_sd15_lora: a95a0f4bdcb9", Version: v1.8.0

ここでファイル名にいつもとの違いを発見。
Seed値が反映されています。

Seed値0

Seed値0ではどうなるのでしょうか。

Top quality, 1 beautiful woman, long Hair, brown hair, wearing Camisole & skirt, shy-smile, Sunlight, at street, 35mm Lens, /1, (white Background: 1.3) <lora:ip-adapter-faceid-plusv2_sd15_lora:1>

Seed値-1

今度はランダムに出る−１。

Top quality, 1 beautiful woman, long Hair, brown hair, wearing Camisole & skirt, shy-smile, Sunlight, at street, 35mm Lens, /1, (white Background: 1.3) <lora:ip-adapter-faceid-plusv2_sd15_lora:1>

Negative prompt: sfw ng:deepnegatives:v.1.7.5t, ((badhandv4)), (worst quality:2), (low quality:2), (normal quality:2), lowres, bad anatomy, bad hands, normal quality, ((monochrome)), watermark

Seed値−2

-2ではどうでしょう。

Top quality, 1 beautiful woman, long Hair, brown hair, wearing Camisole & skirt, shy-smile, Sunlight, at street, 35mm Lens, /1, (white Background: 1.3) <lora:ip-adapter-faceid-plusv2_sd15_lora:1>

Seed値−4

マイナスの値を大きくします。

Top quality, 1 beautiful woman, long Hair, brown hair, wearing Camisole & skirt, shy-smile, Sunlight, at street, 35mm Lens, /1, (white Background: 1.3) <lora:ip-adapter-faceid-plusv2_sd15_lora:1>

Seedはランダムになる−１以外は、同じ画像になることが確認できました。

服装を変える

今度はSeed値を固定して、服装を変えてみたいと思います。
Seed値１の時に生成したこちらの画像を使います。

プロンプトでは、キャミソールとスカートとなっていた服をトレーナーに変えてみます。

腕組のポーズではどうでしょう。

全身

もっとカメラを引いて、全身を確認したい。
standingという単語を入れてみました。

Seedが良くない気がしたので、ランダム値の-1にしてみます。

同一人物って難しい・・・
今回はここまでで断念。

Seed(シード)値の調べ方

最後に、過去に生成した画像のSeed(シード)値の調べ方を記述します。

「PNG info」タブをクリック。
画像をドロップ。
「parameters」で値を確認。

今回は、Seed値を使って同じ人物で違う服・ポーズを試みました。
Seed値を使った方が同一人物に近づける気がします。
上手く作れる人はもっと上手いので、引き続き研究していいプロンプトを発見していきたいと思います。
