Welcome to the world of advanced image processing with Face Upscalers powered by ONNX! This guide will walk you through the steps needed to implement state-of-the-art face upscaling in your applications, making your images sharper and more defined. Let’s dive in!

What are Face Upscalers?

Face upscalers are AI-driven tools that enhance the resolution of facial images. They are particularly useful in scenarios where image quality is crucial, such as in photography or video processing. With ONNX (Open Neural Network Exchange), you can run optimized inference on these models across various platforms.

Getting Started

To get started with ONNX-powered face upscalers, follow these steps:

• Install Prerequisites: Ensure you have Python installed along with the necessary libraries such as ONNX and ONNX Runtime.
• Download the Model: You can download the face upscaler model from the GitHub Downloads.
• Load the Model: Use ONNX Runtime to load the model into your application.

Sample Code

Here’s a simple analogy to understand how the code works. Think of the code as a recipe for making a gourmet meal:

1. **Ingredients (Model)**: Just like you need specific ingredients for a recipe, you need an ONNX model to upscale facial images.

2. **Cooking Method (Inference)**: Following the preparation steps of a recipe is akin to performing inference on your model. You mix your ingredients (data) according to the instructions (code) to get a delicious outcome (upscaled image).

3. **Serving (Output)**: Finally, presenting a meal resembles saving or displaying the newly enhanced image.

import onnxruntime as ort
import numpy as np
from PIL import Image

def upscale_face(image_path):
    # Load the image
    img = Image.open(image_path).convert("RGB")
    
    # Prepare input for the model
    input_array = np.array(img).astype(np.float32)
    
    # Load the ONNX model
    ort_session = ort.InferenceSession("model.onnx")
    
    # Perform inference
    output_array = ort_session.run(None, {"input": input_array})
    
    # Save or display the result
    result = Image.fromarray(output_array[0])
    result.save("upscaled_image.png")

upscale_face("input_image.png")

Troubleshooting

If you run into any issues while utilizing the ONNX-powered face upscalers, here are some troubleshooting tips:

• Model Not Loading: Ensure that you have the correct ONNX model file and that it is compatible with ONNX Runtime.
• Image Format Errors: Verify that your input image is in a format supported by your libraries. JPEG and PNG are often good choices.
• Performance Issues: If inference is slow, ensure that your machine meets the hardware requirements to run ONNX models efficiently.
