TryOn-Adapter: Efficient Fine-Grained Clothing Identity Adaptation for High-Fidelity Virtual Try-On

Conceptos Básicos

The core message of this work is to propose an effective and efficient framework, termed TryOn-Adapter, for virtual try-on that can maintain the identity of the given garment with low computational cost. The key innovations are: 1) decoupling clothing identity into fine-grained factors (style, texture, and structure) and tailoring lightweight modules to precisely control each factor; 2) introducing a training-free technique, T-RePaint, to further reinforce clothing identity preservation while maintaining realistic try-on effects during inference.

Resumen

The paper proposes a novel framework, TryOn-Adapter, for efficient and effective virtual try-on. The key highlights are:

Decoupling clothing identity into three fine-grained factors: style (color and category information), texture (high-frequency details), and structure (spatial adaptive transformation). Each factor is equipped with a tailored lightweight module to enable precise and efficient identity control.

Utilizing a pre-trained diffusion model as the fundamental network, with only the attention layers fine-tuned, to minimize the training consumption.

Introducing the training-free T-RePaint strategy to further enhance clothing identity preservation during inference, without compromising the overall image fidelity.

Integrating an Enhanced Latent Blending Module to maintain consistent visual quality by blending background information from the encoder into the decoder.

Extensive experiments on two widely-used benchmarks demonstrate the state-of-the-art performance of the proposed TryOn-Adapter, with only about half the trainable parameters compared to recent full-tuning diffusion-based methods.

Estadísticas

The paper reports the following key statistics:

The VITON-HD dataset contains 13,679 image pairs of front-view upper-body women and upper garments at 1024 × 768 resolution.
The Dresscode dataset contains 53,792 front-view full-body person and garment pairs from different categories (upper, lower, dresses).

How can the proposed fine-grained identity decoupling and lightweight adaptation modules be extended to other image-to-image translation tasks beyond virtual try-on

The proposed fine-grained identity decoupling and lightweight adaptation modules in the TryOn-Adapter can be extended to other image-to-image translation tasks by adapting the framework to suit the specific requirements of the new task. Here are some ways in which the modules can be applied to different tasks:

Style Preservation Module: The style preservation module can be utilized in tasks such as image colorization, where maintaining the original color style is crucial. By decoupling the style factors and incorporating them into the network with lightweight adaptation techniques, the model can effectively preserve the color information during translation.

Texture Highlighting Module: In tasks like image super-resolution or image inpainting, the texture highlighting module can be beneficial for enhancing high-frequency details and textures. By refining the texture information in the input images, the model can generate more realistic and detailed outputs.

Structure Adapting Module: The structure adapting module, which focuses on spatial cues and structural adjustments, can be applied to tasks like image segmentation or image transformation. By incorporating segmentation maps or structural conditions, the model can ensure accurate spatial transformations and maintain the structural integrity of the images during translation.

By customizing these modules to suit the specific requirements of different image-to-image translation tasks, the TryOn-Adapter framework can be extended to a wide range of applications beyond virtual try-on, providing efficient and effective solutions for various image translation challenges.

What are the potential limitations or failure cases of the T-RePaint strategy, and how can it be further improved to handle more challenging scenarios

The T-RePaint strategy, while effective in enhancing clothing identity preservation during the inference phase, may have some limitations and potential failure cases:

Over-smoothing: In some cases, applying RePaint at early denoising steps may lead to over-smoothing of the image, resulting in loss of fine details and textures.

Artifacts at RePaint Edges: The RePaint process may introduce artifacts at the edges of the regions that are replaced, especially if the transition between the replaced and original regions is not seamless.

Limited Effectiveness for Complex Scenarios: T-RePaint may struggle to handle more complex scenarios where the clothing identity preservation requires intricate details or precise adjustments.

To improve the T-RePaint strategy and address these limitations, the following approaches can be considered:

Adaptive RePaint: Implementing an adaptive mechanism that dynamically adjusts the application of RePaint based on the image content and complexity of the scenario can help optimize the effectiveness of the strategy.

Multi-Step RePaint: Instead of applying RePaint at a single time step, a multi-step RePaint approach with varying levels of intensity and frequency can be explored to achieve a more gradual and controlled enhancement of clothing identity preservation.

Context-Aware RePaint: Incorporating contextual information and semantic understanding into the RePaint process can help ensure that the replaced regions blend seamlessly with the surrounding areas, reducing artifacts and improving overall image quality.

By refining the T-RePaint strategy with these enhancements, it can be further improved to handle more challenging scenarios and deliver superior results in virtual try-on applications.
