How to Use Transformers.js for Image Segmentation with Xenovasegformer_b2_clothes

In the world of machine learning and image processing, the ability to perform image segmentation has become essential. This blog post will guide you through utilizing the Xenovasegformer_b2_clothes model with ONNX weights to perform clothes segmentation using the Transformers.js JavaScript library. Follow the steps below to get started!

Step 1: Installing Transformers.js

Before diving into the code, ensure you have the Transformers.js library installed in your JavaScript environment. You can easily do this using NPM, the package manager for Node.js.

npm i @xenovatransformers

This command installs the necessary package you will need to use the segmentation model.

Step 2: Example Implementation

Once you have the library set up, you can implement the code to perform image segmentation. The code below serves as an example:

import pipeline from @xenovatransformers;

const segmenter = await pipeline(image-segmentation, Xenovasegformer_b2_clothes);
const url = 'https://freerangestock.com/sample/139043/young-man-standing-and-leaning-on-car.jpg';
const output = await segmenter(url);
console.log(output);

Here, we are importing the required pipeline, loading the segmenter model, and passing an image URL for segmentation. The output will reveal details like score, label, and mask for each segmented component.

Understanding the Output

To better understand the output from the segmenter, let’s analogize it to a chef preparing a dish. Each segmented label (like Background, Hair, etc.) can be seen as different ingredients in a recipe, while their respective scores could represent the quality of each ingredient. The output would look something like this:

[
    { score: null, label: 'Background', mask: 'RawImage' },
    { score: null, label: 'Hair', mask: 'RawImage' },
    ...
]

Just like a chef prepares each ingredient before combining them into a delicacy, your image segmentation model isolates each component in the image.

Step 3: Visualize the Outputs

To visualize the segmentation results, you can save the masks generated for each label as images. Use the following code snippet:

for (const l of output) {
    l.mask.save(`${l.label}.png`);
}

This will store each segmented component as a separate image file, allowing you to see the results directly.

Troubleshooting and Notes

While utilizing photogenic models can be seamless, issues can arise. Below are some troubleshooting tips to help you along the way:

• Model Not Found: Ensure you have the correct model name and that the ONNX weights are correctly structured and placed in an ‘onnx’ subfolder.
• Output Issues: If the structure of your output is unexpected, double-check the input image URL and format.
• Installation Problems: Confirm that your npm package is properly installed and up to date.
