4KAgent is a novel AI agent framework designed for universal super-resolution, capable of upscaling any image to 4K resolution. It targets researchers and practitioners in computer vision and image processing who need to handle diverse image types and degradation levels, offering a flexible and adaptive solution for high-resolution image generation.

How It Works

4KAgent employs a multi-agent system. A Perception Agent uses vision-language models (VLMs) to analyze image content and distortions, generating a restoration plan. A Restoration Agent executes this plan through an iterative execution-reflection-rollback loop for recursive upscaling. A Quality-Driven Mixture-of-Experts (Q-MoE) policy selects optimal intermediate images, and a dedicated face restoration pipeline enhances facial details. A Profile Module allows task customization without retraining.
