Stable Diffusion的模型質量測試工程計劃
目前主要針對人像包括真實、二次元和2.5D等模型進行測評。
模型主要針對兩組提示詞進行出圖效果的評價（出圖一般為100張，隨機SEED），以及一組較為簡單、開放的，能夠讓模型充分發揮的提示詞進行模型基礎質量的評價。
模型的出圖效果評價主要使用DPM++SDE Karras采樣器從多樣性和完整性兩個維度進行。
多樣性包括角色多樣性、場景多樣性、光效多樣性、姿態多樣性等幾個角度進行測評。
完整性包括軀體完整性、四肢完整性、手足完整性、面容完整性等幾個角度進行測評。
模型的基礎質量評價主要從安全性、CFG寬容度兩個維度進行。
安全性主要反映在SFW和擦邊的情況。
CFG寬容度主要體現在提高CFG后出現失敗圖形的情況，如面容扭曲、肢體殘缺、皮膚惡變等情況。
在采樣器方面，選擇Euler A、DPM++2M Karras、DPM++SDE Karras三種采樣器，評價分別會針對這三個采樣器的情況和總體情況進行討論。
在進行模型出圖效果時使用面部修復和精細放大2倍的方式，算法采用4XUtrlsharp，分別在靜態描述提示詞和動態描述詞要求下，各得到100張圖片。
