Human Pose Estimator

Overview

This model detects humans and their poses in a given image. The model first detects the humans in the input image and then identifies the body parts, including nose, neck, eyes, shoulders, elbows, wrists, hips, knees, and ankles. Next, each pair of associated body parts is connected by a pose line. The pose lines are assembled into full body poses for each of the humans detected in the image. The model is based on the TF implementation of OpenPose model.

Example Usage

You can test or use this model

• using cURL
• in a Node-RED flow
• in CodePen
• in a serverless app

Test the model using cURL

Once deployed, you can test the model from the command line. For example if running locally:

curl -F "image=@samples/p3.jpg" -XPOST http://localhost:5000/model/predict

You should see a JSON response like that below:

{
  "status": "ok",
  "predictions": [
    {
      "human_id": 0,
      "pose_lines": [
        {
          "line": [
            110,
            53,
            91,
            53
          ]
        },
        {
          "line": [
            110,
            53,
            129,
            50
          ]
        },
        .
        .
        .
        {
          "line": [
            114,
            35,
            119,
            32
          ]
        }
      ]
    }
  ]
}

The information returned from the model can be used to construct and visualize pose lines for the humans detected in the image, such as shown in the example below. For more details see the GitHub README.

Test the model in a Node-RED flow

Complete the node-red-contrib-model-asset-exchange module setup instructions and import the human-pose-estimator getting started flow.

Test the model in CodePen

Learn how to send an image to the model and how to render the results in CodePen.

Test the model in a serverless app

You can utilize this model in a serverless application by following the instructions in the Leverage deep learning in IBM Cloud Functions tutorial.
