大家好,我是小鱼姐姐,近期使用Stable Diffusion比较多,积累整理了一些内容,得空分享给大家。如果你近期正好在关注AI绘画领域,可以看看哦。
本文不包含SD如何安装及使用的内容,比较适合已经解决了安装问题,在寻找合适的大模型及lora,或者想找一些绘画案例给自己的创作带来一些灵感的人。文章总共2000多字,且涉及大量图片,谨慎观看哈。下面正式开始。
Stable Diffusion简介
Stable Diffusion 是由CompVis、Stability AI和LAION共同开发的一个文本转图像模型,它通过LAION-5B子集大量的 512x512 图文模型进行训练,我们只要简单的输入一段文本,Stable Diffusion 就可以迅速将其转换为图像,同样我们也可以置入图片或视频,配合文本对其进行处理。
通俗的解释:
StableDiffusion是一种基于扩散过程的图像生成模型,可以生成高质量、高分辨率的图像。它通过模拟扩散过程,将噪声图像逐渐转化为目标图像。这种模型具有较强的稳定性和可控性,可以生成具有多样化效果和良好视觉效果的图像。

下面推荐几个我在C站挖掘的目前最常用的几个模型:
1、好看人物插画风:
说明:
https://civitai.com/models/1540/unstableinkdream?modelVersionId=40626
优点:画人物特别好看
建议搭配参数: 采样器:DPM++ 2M Karras 步数20
绘画示例:
1、人物角色设计:
提示词示例:((masterpiece)),((nsanely detailed)), ((intricate)),((high quality)) a little girl character, pop-art illustration style, simple,cute, 5 years old girl, full color, blue dress, blue shoes, long brown hair, blue hat, no outline, 3d
基于这个人物尝试制作一个4格漫画:
2、生成类似的背景+不同的人物:
提示词示例:((masterpiece)),((nsanely detailed)), ((HD Quality)),((exquisite face))
background: The background is a construction site, with skyscrapers under construction, feeling in 1990s shenzhen.
character:There is only one 20-year-old smile asian female agent,must appear item:balloon
关于这个模型的一个小技巧:
这个模型其他都好,就是你们看我上面生成的图片人物都很精致很好看,但是就是颜色一直是灰蒙蒙的效果。多方查阅之后,找到一个方法,需要下载一个VAE,然后在设置里面勾选上即可:

LORA
LoRA模型全称是:Low-Rank Adaptation of Large Language Models,通俗的可以理解为Stable-Diffusion中的一个插件,仅需要少量的数据就可以进行训练的一种模型。在生成图片时,LoRA模型会与大模型结合使用,从而实现对输出图片结果的调整。
