QwenImage2.1_Lora_BuildingExtraction_I2I_1.0

Description

An experimental LoRA for Qwen-Image-2.1 that extracts and simplifies building footprints from satellite imagery, aiming to produce building shapes on a transparent background.

Note: This lora is trained by 1km*1km satellite images in 1024 resolution. To get the same output quality, you might need to use the same image input setup.

Intended Use

Designed for preliminary architectural site analysis, urban-context mapping, and simplified building-footprint visualization.

Scope and limitations:

• Building detection and boundaries may be inaccurate or incomplete.
• Non-building objects may be incorrectly detected, and some buildings may be missed.
• Transparency and spatial alignment are not guaranteed.
• Outputs require visual inspection and correction before GIS analysis. This model does not produce authoritative building data.
