AI绘画——webui

最近半年text to image的应用非常火热，区别于之前视觉里的分类和检测等任务，虽然机器能识别图里的东西是什么很有趣，但是这些任务一个3岁左右的小孩基本也能在很短的时间给出正确的答案。而text to image所做的任务要更加复杂一些，这些任务基本都需要受过专业训练的人员花费较长时间才能完成。 而且webui等工具的开源，让更多非专业人士能切实到文本生成图片的震撼。

春节前后就开始体验webui了，这段时间事情有点多，搁置了更新，这次先更新下webui生成图片的效果。下次更新stable diffusion的技术细节!

本文使用webui生成图片，网上有挺多安装教程了，这里不赘述了。

模型下载

首先可以去https://civitai.com/下载需要的模型。可惜的是前几天已经禁止国内IP访问了，好在有些可以部分替代的网站，例如https://www.4b3.com/ai-drawing-model

text2image

生成的时候可以用多组关键词和多个模型生成图片，模型可以设置权重搭配比例，生成混搭的风格。

下面的图使用了两个lora模型，一个是之前比较火热的KoreanDoll，用来生成脸部和身体，另一个是英雄联盟里一些角色的模型，用来生成风格。两种模型混搭后可以出现类似cosplay的效果。
