Virtual try-on (VTON) technology has gained attention due to its potential to
transform online retail by enabling realistic clothing visualization of images
and videos. However, most existing methods struggle to achieve high-quality
results across image and video try-on tasks, especially in long video
scenarios. In this work, we introduce CatV2TON, a simple and effective
vision-based virtual try-on (V2TON) method that supports both image and video
try-on tasks with a single diffusion transformer model. By temporally
concatenating garment and person inputs and training on a mix of image and
video datasets, CatV2TON achieves robust try-on performance across static and
dynamic settings. For efficient long-video generation, we propose an
overlapping clip-based inference strategy that uses sequential frame guidance
and Adaptive Clip Normalization (AdaCN) to maintain temporal consistency with
reduced resource demands. We also present ViViD-S, a refined video try-on
dataset, achieved by filtering back-facing frames and applying 3D mask
smoothing for enhanced temporal consistency. Comprehensive experiments
demonstrate that CatV2TON outperforms existing methods in both image and video
try-on tasks, offering a versatile and reliable solution for realistic virtual
try-ons across diverse scenarios.
