妙鸭相机优势
1. 出图质量高
妙鸭相机的出图质量对标海马体和天真蓝,能够满足用户对高质量照片的需求,让每一位用户都有高质量,而且非常像自己的照片。
2. 服务欠发达地区
妙鸭相机更侧重于服务欠发达地区、有需求却很难享受到精品摄影服务的用户,让摄影服务覆盖到更多地区,让更多用户享受到摄影的乐趣。
3. 成本低
线下店随随便便拍个照基本都得大几百,上千,甚至过万。妙鸭只需九块九,买不了吃亏买不了上当。

技术原理
个人写真模型的能力来自于Stable Diffusion模型的文生图功能,输入文本或提示词,输出对应的图像。
考虑到影响个人写真生成效果的主要因素:写真风格信息和用户人物信息。分别使用线下训练的风格LoRA模型和线上训练的人脸LoRA模型学习上述信息。
个人写真模型的能力分为训练与推断两个阶段:
训练阶段生成用于微调Stable Diffusion模型的图像与文本标签数据,得到人脸LoRA模型;
推断阶段基于人脸LoRA模型和风格LoRA模型生成个人写真图像。

生成了四种风格,跟妙鸭效果差不太多,主要是不花钱,出图快。
