--- library_name: transformers.js tags: - pose-estimation license: apache-2.0 --- https://github.com/open-mmlab/mmpose/tree/main/projects/rtmo with ONNX weights to be compatible with Transformers.js. ## Usage (Transformers.js) If you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@xenova/transformers) using: ```bash npm i @xenova/transformers ``` **Example:** Perform pose-estimation w/ `Xenova/RTMO-l`. ```js import { AutoModel, AutoProcessor, RawImage } from '@xenova/transformers'; // Load model and processor const model_id = 'Xenova/RTMO-l'; const model = await AutoModel.from_pretrained(model_id); const processor = await AutoProcessor.from_pretrained(model_id); // Read image and run processor const url = 'https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/football-match.jpg'; const image = await RawImage.read(url); const { pixel_values, original_sizes, reshaped_input_sizes } = await processor(image); // Predict bounding boxes and keypoints const { dets, keypoints } = await model({ input: pixel_values }); // Select the first image const predicted_boxes = dets.tolist()[0]; const predicted_points = keypoints.tolist()[0]; const [height, width] = original_sizes[0]; const [resized_height, resized_width] = reshaped_input_sizes[0]; // Compute scale values const xScale = width / resized_width; const yScale = height / resized_height; // Define thresholds const point_threshold = 0.3; const box_threshold = 0.3; // Display results for (let i = 0; i < predicted_boxes.length; ++i) { const [xmin, ymin, xmax, ymax, box_score] = predicted_boxes[i]; if (box_score < box_threshold) continue; const x1 = (xmin * xScale).toFixed(2); const y1 = (ymin * yScale).toFixed(2); const x2 = (xmax * xScale).toFixed(2); const y2 = (ymax * yScale).toFixed(2); console.log(`Found person at [${x1}, ${y1}, ${x2}, ${y2}] with score ${box_score.toFixed(3)}`) const points = predicted_points[i]; // of shape [17, 3] for (let id = 0; id < points.length; ++id) { const label = model.config.id2label[id]; const [x, y, point_score] = points[id]; if (point_score < point_threshold) continue; console.log(` - ${label}: (${(x * xScale).toFixed(2)}, ${(y * yScale).toFixed(2)}) with score ${point_score.toFixed(3)}`); } } ```
