The paper proposes a two-stage autoregressive adaptation and acceleration framework to adapt a high-fidelity human video diffusion model for real-time, interactive streaming.

Analysis

This paper addresses the inefficiency of current diffusion-based image editing methods by focusing on selective updates. The core idea of identifying and skipping computation on unchanged regions is a significant contribution, potentially leading to faster and more accurate editing. The proposed SpotSelector and SpotFusion components are key to achieving this efficiency and maintaining image quality. The paper's focus on reducing redundant computation is a valuable contribution to the field.

Analysis

This paper addresses critical issues in multi-subject video generation: scale inconsistency and permutation sensitivity. The proposed MoFu framework, with its Scale-Aware Modulation (SMO) and Fourier Fusion strategy, offers a novel approach to improve subject fidelity and visual quality. The introduction of a dedicated benchmark for evaluation is also significant.
Reference

MoFu significantly outperforms existing methods in preserving natural scale, subject fidelity, and overall visual quality.
