Getting Started with PoseNet PoseNet can be used to estimate either a single pose or multiple poses, meaning there is a version of the algorithm that can detect only one person in an image/video and one version that can detect multiple persons in an image/video. Figure poser how to#Since PoseNet on TensorFlow.js runs in the browser, no pose data ever leaves a user’s computer.īefore we dig into the details of how to use this model, a shoutout to all the folks who made this project possible: George Papandreou and Tyler Zhu, Google researchers behind the papers Towards Accurate Multi-person Pose Estimation in the Wild and PersonLab: Person Pose Estimation and Instance Segmentation with a Bottom-Up, Part-Based, Geometric Embedding Model, and Nikhil Thorat and Daniel Smilkov, engineers on the Google Brain team behind the TensorFlow.js library. What’s more, this can actually help preserve user privacy. And since we’ve open sourced the model, Javascript developers can tinker and use this technology with just a few lines of code. With PoseNet running on TensorFlow.js anyone with a decent webcam-equipped desktop or phone can experience this technology right from within a web browser. While many alternate pose detection systems have been open-sourced, all require specialized hardware and/or cameras, as well as quite a bit of system setup. We hope the accessibility of this model inspires more developers and makers to experiment and apply pose detection to their own unique projects. Ok, and why is this exciting to begin with? Pose estimation has many uses, from interactive installations that react to the body to augmented reality, animation, fitness uses, and more. or multi-pose algorithm - all from within the browser. The algorithm is simply estimating where key body joints are. To be clear, this technology is not recognizing who is in an image - there is no personal identifiable information associated to pose detection. So what is pose estimation anyway? Pose estimation refers to computer vision techniques that detect human figures in images and video, so that one could determine, for example, where someone’s elbow shows up in an image. PoseNet can detect human figures in images and videos using either a single-pose algorithm. In collaboration with Google Creative Lab, I’m excited to announce the release of a TensorFlow.js version of PoseNet, a machine learning model which allows for real-time human pose estimation in the browser. With defaIt runs at 10 fps on a 2018 13-inch MacBook Pro. UPDATE: PoseNet 2.0 has been released with improved accuracy (based on ResNet50), new API, weight quantization, and support for different image sizes.
