dlib-java

Java wrapper for the DLib library

Layout

Overview

There is 3 projects:

• resources: it provided the Resource abstraction which is used in order to load files (either from a JAR or from files)
• models: it contains DLibModels and OpenCVModels which can be used in order to use models for these two libraries (some are embeded into the assembled JAR, some should be located on the filesystem)
• dlib: it's the actual wrapper

The dlib project

It's recommended using SWIG in order to make binding (at least in Java).

In the src/main/native folder, you'll find:

• The include folder which contains the .h headers of the .cpp C++ files
• The swig folder which contains the .i interfaces
• The .cpp files which contains

Requirements

Overview

Building the dlib-java wrapper is quite simple (because it's driven by Maven), but there is some requirements which need to be fulfilled.

You'll need to install:

• OpenCV;
• DLib;
• And a few utilities (make, gcc, swig and wget).

OpenCV

Once OpenCV has been installed on you're system, we need to make the JAR availabled to Maven by running:

mvn install:install-file \
    -Dfile=/usr/share/java/opencv4/opencv-420.jar" \
    -DgroupId="opencv" \
    -DartifactId="opencv" \
    -Dversion="4.2.0" \
    -Dpackaging="jar"

We also should ensure that:

• The /usr/lib/libopencv_java420.so shared libary is present;
• The /usr/include/opencv4 includes are presents.

DLib

Once installed, you should ensure that:

• The /usr/lib/libdlib.so shared library is present;
• The /usr/include/dlib includes are presents.

Installing

The JAR can be installed in your local Maven repository using make install. It may take some time: it will compile OpenCV and DLib... So be ready to wait some time!
