Stable Diffusion的模型质量测试工程计划
目前主要针对人像包括真实、二次元和2.5D等模型进行测评。
模型主要针对两组提示词进行出图效果的评价（出图一般为100张，随机SEED），以及一组较为简单、开放的，能够让模型充分发挥的提示词进行模型基础质量的评价。
模型的出图效果评价主要使用DPM++SDE Karras采样器从多样性和完整性两个维度进行。
多样性包括角色多样性、场景多样性、光效多样性、姿态多样性等几个角度进行测评。
完整性包括躯体完整性、四肢完整性、手足完整性、面容完整性等几个角度进行测评。
模型的基础质量评价主要从安全性、CFG宽容度两个维度进行。
安全性主要反映在SFW和擦边的情况。
CFG宽容度主要体现在提高CFG后出现失败图形的情况，如面容扭曲、肢体残缺、皮肤恶变等情况。
在采样器方面，选择Euler A、DPM++2M Karras、DPM++SDE Karras三种采样器，评价分别会针对这三个采样器的情况和总体情况进行讨论。
在进行模型出图效果时使用面部修复和精细放大2倍的方式，算法采用4XUtrlsharp，分别在静态描述提示词和动态描述词要求下，各得到100张图片。
