Qwen-Image Precise Region Control Model

[image]

Model Introduction

This model is the V2 version of a precise region control model trained based on Qwen-Image. The model architecture uses LoRA, enabling control over the position and shape of each entity by providing textual descriptions and regional conditions (mask maps) for each entity. The training framework is built on DiffSynth-Studio, and the dataset used is the Qwen-Image-Self-Generated-Dataset.

Compared to the V1 version, this model is trained on a self-generated dataset from Qwen-Image, resulting in generated images whose styles are more consistent with the base model.
