OpenCV is arguably the defacto free, open-source computer vision library, but setting it up for usage in a JVM project can be hard because OpenCV itself is written in C++, so there are a bunch of system-dependent things that you need to download/compile/install before you can use it.
JavaCV, written by Bytedeco is a library that makes it more bearable to use OpenCV from JVM projects by providing a bunch of wrapper classes and logic around OpenCV (there’s a lot more to it, see their page for details).
Still, because JavaCV depends on JavaCPP for common and OpenCV C++ wrappers, and JavaCPP requires you to set your target platform (what platform you want to run on), I thought getting started could be easier still.
The following is a list of SBT setting keys that you can set in order to customise the behaviour of the plugin:
1 2 3 4
javaCVPlatform is the one that will be most interesting, since you may want to compile JARs for different target platforms; for a list of supported strings, look at the classifiers supported by JavaCPP presets, or work out the different strings that can result from the JavaCPP Loader.
Feel free to try it out and submit issues, ideas, and PRs at the Github page :)
