DiffSynth-Studio/Qwen-Image-EliGen

Qwen-Image Precise Region Control Model

Model Introduction

This model is a precise region control model trained based on Qwen-Image, with a LoRA architecture. It enables control over the position and shape of each entity by taking as input both textual descriptions and regional conditions (mask maps) for each entity. The training framework is built on DiffSynth-Studio, using the dataset DiffSynth-Studio/EliGenTrainSet.
