打破次元壁！AI图生图“重绘”照片和CG，效果惊艳到我了——
风靡全网的短视频“AI漫画”特效，是用什么手段实现的？
图生图是AI绘画中一个非常有意思的板块，上传一张图片，你可以让AI根据各种不同的风格对图像进行重新绘制，从而实现“打破次元壁”的神奇效果。
在Stable Diffusion里，实现一次图生图只需要3步。这节课，我为你细致地分析了里面的一系列参数设置和随机种子的作用。学完它，你将解锁AI绘画中又一个非常有趣的功能板块。

随机种子的作用：控制随机进程
随机种子的概念：
随机种子（Random Seed）是计算机专业术语，一种以随机数作为对象的以真随机数（种子）为初始条件的随机数。
一般计算机的随机数都是伪随机数，以一个真随机数（种子）作为初始条件，然后用一定的算法不停迭代产生随机数。
在Stable Diffusion中，这组”随机数”控制了AI如何为你扩散、生成一张图片。固定住随机种子，就能让这次生成过程被固定下来，从而使得你在修改提示词或一些基础选项时，图片大的“模样”可以保持相对的一致。
Q：我的重绘结果为什么会和原图“一点都不像”？
A：可以尝试通过以下这些方式改善：
降低重绘幅度：对于较复杂的原图，适当降低重绘幅度可以保证细节的准确呈现；
多写提示词描述：用更多的提示词准确描述呈现对象的各项特征。
