RealESR_Animex4_fp16

RealESR_Animex4_fp16 is an ONNX export of a Real-ESRGAN-based super-resolution model optimized for anime-style content.

Model Description

This repository provides a float16 ONNX version of an anime-focused Real-ESRGAN model designed to upscale stylized images such as anime, cartoons, and line-art content.

Compared to general-purpose models, this variant is tuned to better preserve sharp edges, flat colors, and stylized features.

File

• RealESR_Animex4_fp16.onnx

Intended Use

This model is intended for:

• 4× upscaling of anime and cartoon content
• enhancement of stylized or illustrated images
• video frame upscaling for animated media
• ONNX Runtime based pipelines

Input / Output

• Input: low-resolution image tensor
• Output: 4× upscaled image

Exact preprocessing depends on the host application.

Usage Notes

• Optimized for anime / stylized content
• May produce less natural results on real-world photographs
• FP16 export for improved performance on supported hardware
• Compatible with ONNX Runtime providers (CUDA, TensorRT, DirectML, CPU)
