Prompt 연구

[ahfmrptEkd]

Description

• 실사화 작업을 위한 prompt 연구와 개발 일정을 기입할 예정입니다.
• 이 부분은 "주영" 님이 맡아서 해주실 예정이시고, 연구 과정을 업로드 해주실 예정입니다.

우선 프롬프트에 정답은 없으며 아직까지는 논문에서도 경험적, 귀납적으로 잘되는 방법을 찾으면 된다~ 라 기술합니다. 여러가지 샘플링 메소드, 셋팅을 조절해가면서 괜찮은 프롬프트 추려서 정리해두겠습니다.

긍정 프롬프트 A portrait capturing the essence of a Korean idol, featuring a young woman with clear, radiant skin and a soft, contemplative expression under cool-toned lighting. She wears a white turtleneck, enhancing a pure and serene vibe, with her hair elegantly tied back. The pale blue backdrop complements her cool skin tones. The focus is on her face, centered in the image, with her gaze slightly upward, reflecting a moment of quiet reflection, reminiscent of the tranquility of a winter's day.

추가 적인 문제가 있음.

• Positive prompt 와 Negative prompt에서의 토큰이 둘다 75 이상임.

• Prompt가 둘다 정확하게 유도가 되지않는 현상이 있음.

• 75 토큰이 SD1.5가 Cilp을 통해 한번에 처리하는 토큰의 개수임. 그 이상은 75개가 들어가고 OpenClip을 통해 처리가 됨. 그래서 프롬프트가 잊혀지거나 묻히는 경향이 나오는 거임.

• 오히려 적은 토큰으로 잘 뽑는 방법을 찾는게 중요함.
