This code is an MATLAB implementation of the paper: "Spatio-temporal cuboid pyramid for action recognition using depth motion sequences".

This code requires MATLAB, tested on 64-bit Windows with MATLAB R2015a. It depends on LIBLINEAR as a linear classifier, which has been contained in the folder ./LibMatlab.

The code is setted up for the MSR Action 3D dataset by default.

1. Download the MSRAction3D dataset from https://www.uow.edu.au/~wanqing/#Datasets. And then decompress the file Depth.rar to the directory of this code;
2. Run the file bin2mat.m to convert the orginal binary file *.bin to MATLAB matrix file *.mat;
3. Run the file main.m, and you will get the final result after several minutes:

...
Accuracy = 94.5455% (260/275)
...
