Delving into Asymmetric Information Dynamics for High-Fidelity Virtual Try-On

Read the original on arXiv Computer Vision →

The paper introduces RealFit, a virtual try‑on framework that addresses texture degradation and structural drift caused by symmetric bidirectional attention in Diffusion Transformers. By employing Unidirectional Information Flow to isolate garment conditions from stochastic noise and Decoupled Timestep Modulation to strengthen the conditional signal, RealFit achieves high‑fidelity garment rendering. The method also enables a time‑invariant condition branch and a conditional KV cache, cutting inference time by about 75%.

Understanding and Exploiting Diagonal Attention Sparsity in Autoregressive Image Generation

The paper investigates how attention sparsity behaves in autoregressive image generation, finding a distinct diagonal sparsity pattern due to spatial locality of visual tokens. It introduces a diagonal‑aware sparse attention mechanism that skips KV entries along the diagonal within a recent window, achieving up to 3.1× higher throughput and 1.19× lower latency with less than 2% quality loss compared to dense inference.

ReGain: Restoring Subject Fidelity in Personalization on Synthetic Images

ReGain is a training‑free correction that improves subject fidelity in text‑to‑image diffusion models personalized with synthetic images. The authors show that fine‑tuning on synthetic images degrades fidelity due to inflated classifier‑free guidance, especially at high frequencies. ReGain measures this inflation per frequency band and scales it down during sampling, closing 51‑64% of the fidelity gap on Stable Diffusion v1.5 and improving performance on SDXL and SD 3.5 while preserving text alignment.
