This demo shows how to train and test a human pose estimation using deep neural network. In R2019b, Deep Learning Toolbox(TM) supports low-level APIs to customize training loops and it enables us to train flexible deep neural networks. GPU Coder(TM) also enables us to deploy the trained model to an NVIDIA(R) Jetson(TM) devices. Once deployed, the human pose estimator will be running as a standalone.
This repository includes a pretrained network using the COCO dataset, which was collected by the COCO Consortium (cocodataset.org).
Pose Estimation Toolbox requires the following products:
To deploy the model to a NVIDIA Jetson or Drive platforms, you'll also need the following products.
Download the latest release of this repository. To install, open the .mltbx file in MATLAB.
Open the project file to add paths to related folders if you cloned the GitHub respotory.
Load a pose estimator model.
detector = posenet.PoseEstimator;
First, read a test image, then crop a person and resize it to fit to the network input.
I = imread('visionteam1.jpg'); bbox = [182 74 303 404]; Iin = imresize(imcrop(I,bbox),detector.InputSize(1:2));
Then, perform the pose estimation on the image. To visualise the results we can superimpose the detected keypoints on the original image.
keypoints = detectPose(detector,Iin); J = detector.visualizeKeyPoints(Iin,keypoints); imshow(J);

The network architecture is based on Xiao's pose estimation network which combines upsampling and convolutional parameters into transposed convolutional layers in a much simpler way, without using skip layer connections. We also use COCO dataset which is one of the well known large public human pose dataset.
