PID × Krea2 Detail Enhancement Engine

This is a high-definition detail enhancement application based on Krea2 Turbo PiD Flux2 PiD QwenImage ColorMatchV2.

After the user inputs a prompt, the system first uses Krea2 Turbo to generate a base image. Once the base image is completed, the process will re-encode the image and send it into the PiD high-definition enhancement branches of both the Flux2 route and the QwenImage route. Both branches will use 4-step LCM quick sampling to reconstruct the base image of 1024 classes into a high-definition detailed image closer to 4096 classes.

Unlike ordinary Krea2 text-to-image generation, this process does not end after the creation of the first image. Krea2 is responsible for the subject, composition, lighting, and initial style, while PiD is responsible for high-resolution structural reconstruction, texture enhancement, and detail density improvement. After PiD enhancement is complete, ColorMatchV2 adjusts the colors of the high-definition image to better align with the original Krea2 base image, reducing color deviation, style drift, or tonal inconsistency issues after enhancement.

The current process includes both the Flux2 PiD and QwenImage PiD enhancement routes, making it suitable for comparing differences in sharpness, texture, structural retention, color stability, and overall usability between different PiD models. It is ideal for AI poster upscaling, concept art refinement, character illustration enhancement, wallpaper-level outputs, social media cover upgrades, Krea2 HD production tests, and PiD detail enhancement comparison experiments.
