Java Bindings

The Java language bindings for Darknet/YOLO uses the FFM API (Java Foreign Function and Memory) to perform object detection from within Java applications.

The FFM API requires Java 21 or newer.

Example:

Lorem ipsum dolor sit amet consectetur adipiscing elit.
Sit amet consectetur adipiscing elit quisque faucibus ex.
Adipiscing elit quisque faucibus ex sapien vitae pellentesque.

Installing Darknet/YOLO

This project requires Darknet/YOLO. Before proceeding, please make sure you have built and installed Darknet/YOLO.

The recommended Darknet/YOLO repo to use is the modern Hank.ai one maintained by Stéphane Charette: https://github.com/hank-ai/darknet#building

• If using Windows, you must edit your PATH to include C:/Program Files/Darknet/bin (or whever you installed it). You must restart your command prompt once you edit the PATH.
• If using Linux, then both darknet and libdarknet.so are installed in a common location, so there should be no need to edit anything further.

Once you've followed the instructions to build and install Darknet/YOLO, confirm that it works correctly by running darknet --version.
