Proposes ucVTON, a two-stage Stable Diffusion pipeline that disentangles style (text or image) from texture (full garment, crop, or patch) for photorealistic virtual try-on, using hierarchical balanced CLIP features and position encoding.

Problem

Existing virtual try-on methods are constrained in input types: style is limited to text and texture to small image patches, and full garment images entangle style and texture so they cannot be recombined.

Approach

A two-stage pipeline that first edits a human parsing map to the desired style (text or image), then inpaints textures onto the garment regions using hierarchical, balanced CLIP features from all ViT blocks plus position encoding to handle non-stationary textures.
