画像生成AIに同じ人物を書かせる方法について模索してみた。
私はBing imege creatorを使って画像を作成しています。
既に私の投稿をご覧戴いている人はわかると思いますが、同一人物が異なる顔立ちや髪の色で描かれ一貫性がありません。
そこでchatGPTに一貫性のある人物像を生成させるプロンプトぉ作るようお願いしました。
To consistently generate images of the same character, Emma Lawrence, you can create a detailed description of her appearance as part of your prompt. This way, you can mix this description with other prompts to create various scenes featuring Emma. Here's a description of Emma's appearance:
例としてエマ・ロレンスを作ってもらいました。
"Emma Lawrence has shoulder-length wavy brown hair and expressive hazel eyes. Her face is oval-shaped with a delicate nose and full lips. She is of average height and has a slender build. When working at the restaurant, she usually wears a simple black dress with a white apron."
同一人物とはいかないまでも、鑑賞に耐えうる一貫性はあるのではないでしょうか？
私の思うエマ・ロレンス像とは違いすこしアクの強い人物になりましたが、そのあと２つのシチュエーションで画像を生成させました。
Now, you can use this description to create prompts for the two scenes you've requested:
Emma Lawrence interacting with customers at the table: "Emma Lawrence has shoulder-length wavy brown hair and expressive hazel eyes. Her face is oval-shaped with a delicate nose and full lips. She is of average height and has a slender build. Wearing her simple black dress and white apron, she gracefully approaches a table of customers at the restaurant with a warm, welcoming smile, engaging in friendly conversation while taking their orders."
Emma Lawrence singing while cleaning up the restaurant: "Emma Lawrence has shoulder-length wavy brown hair and expressive hazel eyes. Her face is oval-shaped with a delicate nose and full lips. She is of average height and has a slender build. Dressed in her simple black dress and white apron, Emma is tidying up the restaurant after closing time. As she works, she sings a cheerful tune, making the task more enjoyable."

で、その一貫性を保つためのプロンプトの一般化、つまりテンプレを作るよう指示しました。
To maintain consistency when generating images of a character, you can create a generalized character description template that can be adapted for any character. This template can include key aspects of their appearance, style, and any distinguishing features. Here's a generalized character description template:
"[Character Name] has [hair length and style] [hair color] hair and [eye shape] [eye color] eyes. Their face is [face shape] with a [nose description] and [lip description]. They are [height] and have a [build] build. When in their usual setting, they typically wear [clothing description]."
You can fill in the details for any character using this template to create a consistent appearance. By combining this character description with other prompts, you can create various scenes featuring the character while maintaining their recognizable features.
で、このキャラクターの一貫性維持テンプレによって、私だけでなく、あなたもエマ・ロレンスの画像を生成できるわけです。低スプレイヤーにしたり、登山家にしたり、スタートレックのヴォイジャーの艦長にすることもできるわけです。
Emma Lawrence as a tennis player: "Emma Lawrence has shoulder-length wavy brown hair and expressive hazel eyes. Her face is oval-shaped with a delicate nose and full lips. She is of average height and has a slender build. Dressed in a sporty white tennis outfit and tennis shoes, Emma is on the court, skillfully swinging her racket as she competes in a high-stakes tennis match."
Emma Lawrence as a mountain climber: "Emma Lawrence has shoulder-length wavy brown hair and expressive hazel eyes. Her face is oval-shaped with a delicate nose and full lips. She is of average height and has a slender build. Wearing weather-resistant climbing gear, including a harness, helmet, and hiking boots, Emma bravely scales a challenging mountain, gripping onto the rock face as she ascends toward the peak."
Emma Lawrence as a Borg from Star Trek: Voyager: "Emma Lawrence has shoulder-length wavy brown hair and expressive hazel eyes. Her face is oval-shaped with a delicate nose and full lips. She is of average height and has a slender build. Now assimilated into the Borg Collective, her appearance has been altered with cybernetic implants and a cold, emotionless expression. Dressed in a dark, form-fitting Borg uniform, Emma stands with other Borg drones, ready to carry out the Collective's orders."
あ、違った。ボーグにしちゃった。って顔にパーツついてねーし・・
