AI自制壁纸的创新方法：

现在的stable diffusion模型已经能生成几个MB的高清图像了，使用专精于二次元的绘画AI，也经常可以跑出不错的图来。再配合使用图像增强AI，增强图像的大小，完全可以拿来当壁纸使用，所以，咳咳，你懂的……

补充个参数资料： 18:9 市面上的全面屏手机大多采用这个比例。

电脑显示器一般主流比例是16：9

AI绘画是当下炙手可热的新技术，能够推动绘画行业发生变革，也能够吸引喜欢整活的人接触。毕竟对非美术生来说，只要敲敲键盘就能得到一幅精美画作这种事情，还是感觉挺新奇的。

作为一个不使用魔法的新时代青年大学生，只能在Great Fire Wall之内进行对AI绘画进行探索。所以探索经验皆可由各路AI绘画兴趣者所有效借鉴，请放心食用。

我并没有尝试过novelai生成二次元形象，但对画画感兴趣的人一定都对二次元美图更感兴趣，所以我就扒来了一些负面词提供参考。毕竟，有谁会拒绝可爱的女孩子呢？

四、经验之谈

相似度调太高会产生突兀线条，太低会模糊抽象

使用AI来优化线稿，会有不错效果

｛｝是减弱，（）是增强，是1.2倍，就是削弱或者突出某一部分的细节。[]是特别指定。

正面词tag和负面词tag:使用负面词可以约束AI产生残肢多器官，以及对肢体进行微调，捏出清奇的结构，比如猫耳兽娘。

风景画宜加宽

各平台的Tag编写规则会有所不同，有专门的Tag生成器。

目前的AI作画对于任何动物的生成都会出现肢体混乱等现象，但却能生成很精美的场景。使用ps给生成图上加上人物主体，再修改一下光影关系，产生的效果很不错，至少能够省下画师画部分场景的时间。
