The task of video virtual try-on aims to fit the target clothes to a person
in the video with spatio-temporal consistency. Despite tremendous progress of
image virtual try-on, they lead to inconsistency between frames when applied to
videos. Limited work also explored the task of video-based virtual try-on but
failed to produce visually pleasing and temporally coherent results. Moreover,
there are two other key challenges: 1) how to generate accurate warping when
occlusions appear in the clothing region; 2) how to generate clothes and
non-target body parts (e.g. arms, neck) in harmony with the complicated
background; To address them, we propose a novel video virtual try-on framework,
ClothFormer, which successfully synthesizes realistic, harmonious, and
spatio-temporal consistent results in complicated environment. In particular,
ClothFormer involves three major modules. First, a two-stage anti-occlusion
warping module that predicts an accurate dense flow mapping between the body
regions and the clothing regions. Second, an appearance-flow tracking module
utilizes ridge regression and optical flow correction to smooth the dense flow
sequence and generate a temporally smooth warped clothing sequence. Third, a
dual-stream transformer extracts and fuses clothing textures, person features,
and environment information to generate realistic try-on videos. Through
rigorous experiments, we demonstrate that our method highly surpasses the
baselines in terms of synthesized video quality both qualitatively and
quantitatively.
