# Qwen-Image 精确分区控制模型

![](./assets/title.png)

## 模型介绍

本模型是基于 [Qwen-Image](https://www.modelscope.cn/models/Qwen/Qwen-Image) 训练的精确分区控制模型，模型结构为 LoRA，可以通过输入每个实体的文本和区域条件（蒙版图）来控制每个实体的位置和形状。训练框架基于 [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio) 构建，采用的数据集是 [DiffSynth-Studio/EliGenTrainSet](https://www.modelscope.cn/datasets/DiffSynth-Studio/EliGenTrainSet)。
