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

<strong>MPOSE2021</strong> MPOSE2021 is a Dataset for short-time pose-based Human Action Recognition (HAR). MPOSE2021 is specifically designed to perform short-time Human Action Recognition, as presented in [12]. 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 is remapped to a common and homogeneous list of actions. To properly use MPOSE2021 and all the functionalities developed by the authors, we recommend using the official repository MPOSE2021_Dataset. <strong>Dataset Description</strong> The repository contains 3 datasets (namely 1, 2 and 3) which consist of the same data divided in different train/test splits. Each dataset contains X and y numpy arrays for both training and testing. X has the following shape: <pre>(number_of_samples, time_window, number_of_keypoints, x_y_p)</pre> where time_window = 30 number_of_keypoints = 17 (PoseNet) or 13 (OpenPose) x_y_p contains 2D keypoint coordinates (x,y) in the original video reference frame and the keypoint confidence (p &lt;= 1) <strong>References</strong> [1] F.
