Hierarchical Cross-Attention Network for Virtual Try-On

In this paper, we present an innovative solution tailored for the intricate challenges of the virtual try-on task–our novel Hierarchical Cross-Attention Network, HCANet. HCANet is meticulously crafted with two primary stages: geometric matching and try-on, each playing a crucial role in delivering realistic and visually convincing virtual try-on outcomes. A distinctive feature of HCANet is the incorporation of a novel Hierarchical Cross-Attention (HCA) block into both stages, enabling the effective capture of long-range correlations between individual and clothing modalities. The HCA block functions as a cornerstone, enhancing the depth and robustness of the network. By adopting a hierarchical approach, it facilitates a nuanced representation of the interaction between the person and clothing, capturing intricate details essential for an authentic virtual try-on experience. Our extensive set of experiments establishes the prowess of HCANet. The results showcase its cutting-edge performance across both objective quantitative metrics and subjective evaluations of visual realism. HCANet stands out as a state-of-the-art solution, demonstrating its capability to generate virtual try-on results that not only excel in accuracy but also satisfy subjective criteria of realism. This marks a significant step forward in advancing the field of virtual try-on technologies.
