Keras implementation of "skeleton transformer module", which is mentioned in Skeleton-based Action Recognition with Convolutional Neural Networks.

Install

You can install this module from PyPI as skeraton.

pip install skeraton

How to use

Module

skeraton.SkeletonTransformer

Parameters:

All parameters are required.

timesteps: Timesteps of input time-series data (equal to number of frames, mentioned as 'T' in the paper)
kpts_dim: Dimentions of keypoints (usually 2 (x, y) or 3 (x, y, z)) output_dim: Dimentions of output (mentioned as 'M' in the paper)

Input:

x: 3-dimentional tensor of shape (batchsize, timesteps, kpts_dim*N) where N is number of joints
