Keypoint Detection

Our model uses a convolutional neural network with a recurrent module to detect body keypoints from a single image. Below, we provide code to train and test the model.

Software Dependencies

You need MATLAB and the MatConvNet toolbox to run this demo. This demo has been compiled and tested for Matlab 2016a, CUDNN v5.1 and cuda 8.0 (using a Linux machine).

Train Model (MPII Human Pose Dataset)

1. Download and prepare the dataset by executing getMPIIData_v3.m and then splitMPIIData_V4.m.
   • The data preparation takes several minutes to be completed. The output is the train (MPI_imdbsT1aug0.mat, ~3GB) and validation (MPI_imdbsV1aug0.mat, ~0.3GB) files.
2. Execute trainBodyPose_example.m (need to set some parameters such as MatConvNet path and GPU index).
3. To test model, run the demo that follows is explained below.

Parameters for training a model with one recurrent iteration:

net = initialize3ObjeRecFusion(opts,2,0,'shareFlag',[0,1]);

opts.derOutputs = {'objective1', 1,'objective2', 1, 'objective4', 1,'objective5', 1, 'objective7', 1,'objective8', 1};

Parameters for training a model with two recurrent iterations (default):

net = initialize3ObjeRecFusion(opts,3,0,'shareFlag',[0,1,1]);

opts.derOutputs = {'objective1', 1,'objective2', 1, 'objective4', 1,'objective5', 1, 'objective7', 1,'objective8', 1, 'objective10', 1,'objective11', 1};

Run Demo

1. Download a pre-trained model if you haven't trained one.
2. Execute demo_keypoint.m.

Run Live Demo

You need to have the Web-Camera package installed and set the path to it.

1. Download a pre-trained model if you haven't trained one.
2. Execute demolive_keypoints.m.
