OpenIMAJ Jar Files

I am new to openIMAJ and I want to process some pictures using it. There are a lot of tutorial available but they all tell using Maven. Does anyone know from where I can download the jar files of openIMAJ to directly use in my Java project? Thanks!

Solution

  • OpenIMAJ is rather complex and contains a lot of modules that you probably don't need to use in your project (i.e. if your making something to do image processing, you probably don't care to much about audio analysis, or content analysis of web-pages). In addition each of the OpenIMAJ modules has dependencies on numerous other projects (which themselves have dependencies, and so on). For these reasons, it isn't really all that practical to provide direct downloads of all the modules and their dependencies as it would take an incredible effort for the user to try and figure out which bits are needed and which bits are not.

    The ideal way to specify which bits of OpenIMAJ you need is to use an automatic dependency management system; this does not need to be Maven however - any Maven compatible dependency manager will work (i.e. Ivy, SBT, Grape, etc...). There are examples of the snippets you need to add to your build system configuration for these on the OpenIMAJ front page in the box on the right (you might need to scroll down a bit).

    If you really do want to manually include the relevant jar files in your existing project, I'd recommend the following approach, which uses Maven to build a customised set of jars based on the exact OpenIMAJ modules you need:

    1. Run mvn -DarchetypeRepository=http://maven.openimaj.org -DarchetypeArtifactId=openimaj-quickstart-archetype -DarchetypeGroupId=org.openimaj -DarchetypeVersion=1.2.1 -DartifactId=oi-deps -DgroupId=oi-deps -Dversion=1.0-SNAPSHOT -DinteractiveMode=false archetype:generate to create a basic OpenIMAJ project (called oi-deps in this case).
    2. Go to the oi-deps directory: cd oi-deps
    3. Edit the pom.xml file to include only the bits of OpenIMAJ you need by removing any unnecessary <dependency> sections.
    4. Run mvn dependency:copy-dependencies. This will create a target/dependencies folder that contains all the jars you need to add to your project.
