MPOSE2021: a Dataset for Short-time Pose-based Human Action Recognition

MPOSE2021

A Dataset for Short-time Pose-based Human Action Recognition

This repository contains the MPOSE2021 Dataset for short-time pose-based Human Action Recognition (HAR). MPOSE2021 is specifically designed to perform short-time Human Action Recognition.

MPOSE2021 is developed as an evolution of the MPOSE Dataset [1-3]. It is made by human pose data detected by OpenPose [4] and Posenet [11] on popular datasets for HAR, i.e. Weizmann [5], i3DPost [6], IXMAS [7], KTH [8], UTKinetic-Action3D (RGB only) [9] and UTD-MHAD (RGB only) [10], alongside original video datasets, i.e. ISLD and ISLD-Additional-Sequences [1]. Since these datasets have heterogenous action labels, each dataset labels are remapped to a common and homogeneous list of actions.

This repository allows users to generate pose data for MPOSE2021 in a python-friendly format. Generated sequences have a number of frames between 20 and 30. Sequences are obtained by cutting the so-called Precursor videos (from the above-mentioned datasets), with non-overlapping sliding windows. Frames where OpenPose/PoseNet cannot detect any subject are automatically discarded. Resulting samples contain one subject at a time, performing a fraction of a single action. Overall, MPOSE2021 contains 15429 samples, divided into 20 actions, performed by 100 subjects.

The overview of the action composition of MPOSE2021 is provided in the following image:

Below, the steps to install the mpose library and obtain sequences are explained. Source code can be found in the MPOSE2021 repository.

Installation

Install MPOSE2021 as python package from PyPi

pip install mpose

Getting Started

# import package
import mpose

# initialize and download data
dataset = mpose.MPOSE(pose_extractor='openpose', 
                      split=1, 
                      transform='scale_and_center', 
                      data_dir='./data/')

# print data info 
dataset.get_info()

# get data samples (as numpy arrays)
X_train, y_train, X_test, y_test = dataset.get_dataset()
