# 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)

## Source / Attribution

This repository contains an ONNX-packaged version of a Real-ESRGAN-based model.

## Limitations

- May oversharpen or distort real-world photographic content
- GAN-based models can introduce artificial detail
- Output quality depends on input resolution and preprocessing
