【Stable Diffusion】图生图 超详细使用方法和参数设置诀窍
TLDRAI小王子的教程详细介绍了Stable Diffusion图生图的使用方法和技巧,包括重绘强度、缩放模式、局部重绘、涂鸦绘制等功能的详细讲解,以及如何通过插件和特定参数设置来优化图像生成效果。
Takeaways
- 📌 介绍Stable Diffusion图生图的使用方法和技巧,适合初学者和对图生图有疑惑的用户。
- 🎨 重绘强度是图生图的核心,通过调整denoising值(0到1之间)来控制原图与生成图的相似度。
- 🖼️ 图生图页面包含正向提示词、反向提示词以及图片上传框,用于上传基础图片。
- 🌠 缩放模式有四种:拉伸、裁剪、填充和直接缩放,根据需求选择合适的模式调整图像尺寸和比例。
- 👁️ 面部修复、宽高比、生成次数、CFG引导和种子等参数与文生图相同,但图生图独有的参数包括缩放模式和重绘强度。
- 🎨 通过调整CFG scale和重绘强度,可以在保持人物不变的情况下修改背景和场景。
- 🖌️ 涂鸦绘制功能允许用户直接在图上绘制,并通过调整重绘强度和笔刷大小来实现细节修改。
- 👓 局部重绘功能通过蒙版和模糊度调整实现AI变脸等局部修改,适用于精细调整图像特定区域。
- 📂 批量处理功能可以处理多个图像和蒙版,要求所有文件夹路径必须是英文,确保输入目录和输出目录设置正确。
- 🔄 反推功能可以通过上传图片来推导可能的提示词,有助于理解已有图像的生成逻辑。
- 🔧 插件如all-in-one-prompt和canvaszoom可以增强Stable Diffusion的功能,提高用户操作的便捷性和精确度。
Q & A
什么是图生图?
-图生图是一种使用Stable Diffusion技术,将给定的图片转换成用户想要的另一种风格或元素的图片的过程。
Stable Diffusion图生图的主要使用方法有哪些?
-主要使用方法包括局部重绘涂鸦重绘、局部绘制涂鸦蒙版、局部上传蒙版和批量处理等。
重绘强度的作用是什么?
-重绘强度决定了图生图的变化程度。强度较低时,生成的图片与原图更相似。

🎨 Introduction to Image Synthesis Techniques
This paragraph introduces viewers to the methods and skills of image synthesis, emphasizing the comprehensive nature of the tutorial. It begins by suggesting viewers like and subscribe due to the detailed coverage of stable diffusion image synthesis. The speaker addresses common confusions regarding various features such as局部重绘 (local redrawing), 涂鸦重绘 (doodle redrawing), and batch processing. The introduction of the all-in-one-prompt plugin is mentioned, with a promise to cover its usage in future content. The speaker then guides viewers through the web interface, highlighting differences from text-to-image synthesis and explaining the importance of having a base image for image synthesis. Parameters like 重绘强度 (redrawing intensity) are discussed, with examples to illustrate their impact on the final image. The paragraph concludes with an overview of other features such as 缩放模式 (scaling mode) and 图像上传 (image upload).
🖌️ Exploring Drawing and Image Synthesis Tools
The second paragraph delves into the specifics of using the drawing tools for image synthesis. It demonstrates how to adjust the background of an image by adding keywords and modifying the CFG scale and redrawing intensity. The speaker also introduces the sketching feature, explaining the differences between sketching and regular image synthesis. The paragraph covers the use of additional tools like the color palette, brush size adjustment, and the eraser. The speaker recommends a plugin called canvaszoom for better zooming capabilities and provides a brief overview of its functions. The paragraph concludes with a showcase of how sketching can transform simple doodles into fully rendered images, highlighting the power of the image synthesis tool.
🎭 Understanding Local Renovation and Masking
This paragraph focuses on the use of local renovation and masking in image synthesis. It explains the role of mask blur in softening the edges of the masked areas, allowing for smoother transitions in the final image. The speaker provides a practical example of changing a character's hair color, illustrating the effect of different mask blur settings. The paragraph further clarifies the differences between fill mode and original image mode, as well as the impact of latent noise on image detail and creativity. The speaker also discusses the choice between full-image and mask-only rendering for局部重绘 (local redrawing), emphasizing the importance of selecting the appropriate option for the desired level of detail in the final image.
🖼️ Advanced Masking and Batch Processing
The fourth paragraph discusses advanced masking techniques, including the use of the inpainting sketch tool, which allows for colored masks in addition to the standard black and white. The speaker explains the significance of mask transparency and its effect on the final rendering. The paragraph then transitions to discussing batch processing, detailing the requirements for folder paths and the importance of maintaining English naming conventions to avoid errors. The speaker provides a step-by-step guide on setting up batch processing, including the preparation of input and output directories and the organization of mask images. The paragraph concludes with an explanation of the clip reverse-engineering feature, which can deduce keywords from an image, and mentions a more precise plugin called Trigger for future discussion.
🚀 Conclusion and Future Tutorials
In the final paragraph, the speaker wraps up the tutorial by reiterating the value of the content provided and encouraging viewers to like and subscribe for more tutorials. The speaker promises to cover other useful plugins for stable diffusion in a future video, aiming to help viewers master AI tools more effectively. The paragraph ends with a call to action for viewers to follow the channel for easy access to AI-related content and tutorials.
