Skeletics 152

Introduction

Skeletics 152 is a in the wild human action dataset made using the videos from much larger Kinetics-700 dataset

Since Kinetics 700 contains many categories which can't be considered to be of human actions, a more focused subset of these categories was manually picked and this Skeletics 152 dataset was created.

Number of classes Number of Samples
Kinetics 700 700 650,000
Skeletics 152 152 125,657

Download Dataset

Skeletics 152 dataset can be downloaded from this link

A .zip file will be downloaded from this link which will contain, two more .zip files:

  1. vibe_results_train.zip
  2. vibe_results_val.zip

Which contains VIBE skeleton results for train and validation split respecitvely.

Inside each of these .zip files there will be folders with the name of different classes and inside each folder there will be json files containing VIBE skeleon results for different video samples in that class.

Dataset preparation

To obtain 3d skeletons from the RGB video, VIBE pose estimation model is used. VIBE pose estimatation gives 49 joints in total out of which we are choosing 25 body joints.

The final videos are then split randomly into 80:20 train-val split.

Samples

Some samples of the vibe skeleton estimations on the RGB video are shown below.
