BlazePose Video Pose Estimation

This repository contains Python code that uses the BlazePose model from the Mediapipe library to estimate the pose of a person in a video file. The code can detect 33 body keypoints, including face, hands, and feet, and returns a processed video object and the output from the model for each frame.

Usage

To use the code, simply run the video_pose_estimation function in the blazepose_simple_use_case_example.ipynb notebook. This function takes a video file path as input and returns a processed video object, as well as two data frames containing the x, y, and z coordinates of each landmark for each frame of the processed video and the visibility score for each landmark for each frame of the processed video.

Example

You can find an example of how to use this code in the blazepose_simple_use_case_example.ipynb notebook. This notebook demonstrates how to upload a video file to Google Colab, apply the pose estimation model to each frame of the video, and view the results. Open In Colab

Installation

Option 1: Local Installation

  1. Clone this repository: git clone https://github.com/ItayCoifman/blazepose-mediapipe-example.git
  2. Navigate to the repository: cd blazepose-mediapipe-example
  3. Create a new virtual environment (optional): python -m venv venv
  4. Activate the virtual environment (optional): source venv/bin/activate
