AgentHOI: Multi-Agent Reasoning for Human-Object-Interaction Video Generation via Implicit Representation Alignment

2026-07-24 · Source: Computer Vision and Pattern Recognition · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Computer Vision · Depth: Expert, quick

Summary

AgentHOI is a novel text-driven framework for human-object interaction (HOI) video generation, introduced to overcome the limitations of existing methods that rely on explicit motion control. This approach employs a "thinking-before-generation" paradigm, utilizing multi-agent reasoning for perception, interaction, and motion planning to bridge high-level textual intent with physical execution. AgentHOI further enhances text-driven motion understanding through an implicit text-motion alignment strategy, which distills text-to-motion priors directly into a video diffusion model. This innovation allows for robust HOI synthesis without requiring explicit motion inputs during inference. Experimental results demonstrate that AgentHOI significantly improves interaction naturalness, preserves object appearance, and adheres more effectively to complex textual instructions, particularly in challenging object-centric scenarios such as wearing and riding. The code is publicly available.

Key takeaway

For Computer Vision Engineers developing robust human-object interaction video generation systems, AgentHOI's "thinking-before-generation" framework and implicit text-motion alignment offer a significant advancement. You should consider integrating multi-agent reasoning and prior distillation techniques to achieve more natural interactions and better object appearance preservation from complex textual instructions. This method reduces reliance on explicit motion inputs, streamlining your workflow for diverse object-centric scenarios.

Key insights

AgentHOI uses multi-agent reasoning and implicit text-motion alignment for robust, text-driven HOI video generation without explicit motion inputs.

Principles

• Adopt a "thinking-before-generation" framework.
• Employ multi-agent reasoning for complex interactions.
• Distill text-to-motion priors implicitly.
