Pose estimation example

Pose estimation is a computer vision technique for determining the pose of an object in an image.

In this example, you learn how to implement inference code with a ModelZoo model to detect dogs in an image.

The source code can be found at PoseEstimation.java.

Setup guide

Follow setup to configure your development environment.

Run pose estimation example

Input image file

You can find the image used in this example in the project test resource folder: src/test/resources/pose_soccer.jpg

soccer

Build the project and run

Use the following command to run the project:

cd examples
./gradlew run -Dmain=ai.djl.examples.inference.PoseEstimation

Your output should look like the following:
