# Real-CUGAN Models for TensorFlow.js
|
| 2 |
+
|
| 3 |
+
[](https://huggingface.co/shammisw/real-cugan-tensorflowjs)
|

|

+
|
| 6 |
+
This repository provides pre-converted models of **Real-CUGAN** (Real-World-Oriented Cascaded U-Net for Anime Image Super-Resolution) in the **TensorFlow.js GraphModel format**, ready for use in web browsers and Node.js environments.
|
| 7 |
+
|
| 8 |
+
These models are optimized for upscaling anime-style images and illustrations with high fidelity, speed, and reduced noise.
|
| 9 |
+
|
| 10 |
+
## β¨ Features
|
| 11 |
+
|
| 12 |
+
* **High-Quality Anime Upscaling:** Specifically trained for cartoons and anime, preserving sharp lines and details.
|
| 13 |
+
* **Web Ready:** Run directly in the browser with TensorFlow.js for client-side image processing.
|
| 14 |
+
* **Multiple Scales & Models:** Includes various models for different upscaling factors and noise reduction levels.
|
| 15 |
+
* **Lightweight & Fast:** CUGAN is designed to be more efficient than many larger GAN-based upscalers.

## π Usage Example
|
| 20 |
+
|
| 21 |
+
To use these models, you will need to have TensorFlow.js set up in your project.
|
| 22 |
+
|
| 23 |
+
```bash
|
| 24 |
+
# Using npm
|
| 25 |
+
npm install @tensorflow/tfjs
|
| 26 |
+
|
| 27 |
+
# Using yarn
|
| 28 |
+
yarn add @tensorflow/tfjs
|
| 29 |
+
```
|
| 30 |
+
|
| 31 |
+
Here is a basic example of how to load and run a model in JavaScript:
|
| 32 |
+
|
| 33 |
+
```javascript
|
| 34 |
+
import * as tf from '@tensorflow/tfjs';
|
| 35 |
+
|
| 36 |
+
// The URL to the model.json file in this repository
|
| 37 |
+
const MODEL_URL = '[https://huggingface.co/shammisw/real-cugan-tensorflowjs/resolve/main/real-cugan-models/realcugan/4x-conservative-64/model.json](https://huggingface.co/shammisw/real-cugan-tensorflowjs/resolve/main/real-cugan-models/realcugan/4x-conservative-64/model.json)';
|
| 38 |
+
|
| 39 |
+
async function upscaleImage(imageElement) {
|
| 40 |
+
try {
|
| 41 |
+
// 1. Load the model
|
| 42 |
+
console.log('Loading model...');
|
| 43 |
+
const model = await tf.loadGraphModel(MODEL_URL);
|
| 44 |
+
console.log('Model loaded.');
|
| 45 |
+
|
| 46 |
+
// 2. Prepare the input tensor from an HTMLImageElement
|
| 47 |
+
// Models are trained on float32 tensors, normalized to the [0, 1] range.
|
| 48 |
+
const inputTensor = tf.browser.fromPixels(imageElement)
|
| 49 |
+
.toFloat()
|
| 50 |
+
.div(255.0)
|
| 51 |
+
.expandDims(0); // Add batch dimension: [h, w, c] -> [1, h, w, c]
|
| 52 |
+
|
| 53 |
+
// 3. Run inference
|
| 54 |
+
console.log('Running inference...');
|
| 55 |
+
const outputTensor = model.execute(inputTensor);
|
| 56 |
+
|
| 57 |
+
// 4. Process the output and display it on a canvas
|
| 58 |
+
const outputCanvas = document.getElementById('output-canvas');
|
| 59 |
+
await tf.browser.toPixels(outputTensor.squeeze(), outputCanvas);
|
| 60 |
+
console.log('Upscaling complete!');
|
| 61 |
+
|
| 62 |
+
// 5. Clean up tensors
|
| 63 |
+
tf.dispose([inputTensor, outputTensor]);
|
| 64 |
+
|
| 65 |
+
} catch (error) {
|
| 66 |
+
console.error('Failed to upscale image:', error);
|
| 67 |
+
}
|
| 68 |
+
}
|
| 69 |
+
|
| 70 |
+
// Find your input image element and pass it to the function
|
| 71 |
+
const myImage = document.getElementById('my-input-image');
|
| 72 |
+
upscaleImage(myImage);
|
| 73 |
+
```

+
* **Original Real-CUGAN Models:** The foundational research and PyTorch models were developed by **Bilibili AI Lab**. Their incredible work made this possible.
|
| 94 |
+
* **GitHub Repository:** [bilibili/ailab/Real-CUGAN](https://github.com/bilibili/ailab/tree/main/Real-CUGAN)
|
