In the fascinating world of computer vision, semantic segmentation takes the spotlight by assigning a class to each pixel of an image, allowing us to grasp the intricacies of shapes within those images. Think of it as turning a fuzzy, watercolor painting into a detailed blueprint of the subjects within. Today, we will delve into how to host your Keras segmentation models and the steps involved in achieving precise image segmentation.

Understanding Image Segmentation

Before we jump into hosting models, let’s clarify what semantic segmentation is. Imagine you have a picture of a cat lounging on a colorful mat. Instead of just knowing there’s a cat (like image classification does) or marking a box around it (as in object detection), semantic segmentation labels every pixel in the image as belonging to either the cat or the background. The journey from the raw output of a model to a readable format involves a few critical steps.

Steps to Host Your Keras Segmentation Models

• Model Training: Train your Keras model using image segmentation datasets, such as the Oxford IIT Pets dataset. Ensure you’re familiar with the architecture suitable for segmentation tasks.
• Processing the Raw Output: The model will return a raw classification per pixel, which may not be readable. This looks like the image below:

• Creating Masks: Convert the raw output into different binary masks for each class in your image. This involves transforming each mask into a Base64 format for better readability. The expected binary mask output can be seen in this image:

• Returning Predictions: After creating masks, your output function should return a list of dictionaries for each class, including its label, Base64 code, and a fixed score of 1.0.

Example Output Format

Your model’s predictions should resemble this format:

[
    {
        "label": "cat",
        "base64": "...",
        "score": 1.0
    },
    {
        "label": "background",
        "base64": "...",
        "score": 1.0
    }
]

This method allows your model to return clear segmentation information that can be displayed or further processed.

Troubleshooting

If you encounter issues while implementing these steps, consider the following troubleshooting tips:

• Model Not Producing Expected Outputs: Ensure your training dataset is well-prepared and correctly labeled. If you’re using pre-trained weights, check the compatibility with your model architecture.
• Base64 Conversion Fails: Double-check the encoding process; ensure that your image processing pipeline correctly handles image data before the conversion step.
• Hosting Issues: If you are having trouble hosting your models, revisit your configuration settings on the Hub. It may also be beneficial to consult documentation or community forums.
