Fall Detection using OpenPifPaf's Human Pose Estimation model

Fall Detection using Pose Estimation

Introduction

Fall Detection model based on OpenPifPaf

PyPI Library: https://pypi.org/project/openpifpaf/

The detection can run on both GPU and CPU, on multiple videos, RTSP streams, and webcams/USB cameras. Unlike most open-source fall detection models that work on large single subjects, this improved model integrates a person tracker that can detect falls in scenes with more than one person.

Demo Videos

Video credits: 50 Ways to Fall (Link), ran on a single NVIDIA Quadro P1000

Test Results

UR Fall Detection Dataset (Link), tested on two NVIDIA Quadro GV100s.

• Precision: 100%
• Recall: 83.33%
• F1 Score: 90.91%

Note: Due to lack of available datasets, false positives and true negatives were not tested.

Environment

• Ubuntu 18.04 x86_64
• Python 3.7.6
• Anaconda 3
• CUDA 10.2

Usage

Setup Conda Environment

$ conda create --name falldetection_openpifpaf python=3.7.6
