Cloning GIT Repository

The bleeding edge source code can be obtained by cloning the git repository.

git clone -b SNAPSHOT --recursive https://github.com/lessthanoptimal/BoofCV.git boofcv

Is the data directory empty? That's because you didn't follow instructions and skipped --recursive. Fix that by doing the following.

cd boofcv
git submodule update --init --recursive

Quick Start Examples and Demonstrations

Know what you're doing and you just want to see something running? Then run the commands below! Each jar will open a window, then to run an application just double click on its name.

cd boofcv
./gradlew examples
java -jar examples/examples.jar
./gradlew demonstrations
java -jar demonstrations/demonstrations.jar

All the code for what you see is in boofcv/examples and boofcv/demonstrations. Example code is designed to be easy to understand so look there first.

Maven Central Repository

BoofCV is on Maven Central and can be easily added to your Maven, Gradle, ...etc projects. It's divided up into many modules. The easiest way to include the critical modules is to have your project dependent on 'core'.

For Maven projects:

<dependency>
  <groupId>org.boofcv</groupId>
  <artifactId>boofcv-core</artifactId>
  <version>0.31</version>
</dependency>

There are also several integration modules which help BoofCV interact with external projects. A list of those is included below:

Name	Description
boofcv-core	All the core libraries without any of the integration modules listed below
boofcv-android	Useful functions for working inside of Android devices.
boofcv-javacv	JavaCV is a wrapper around OpenCV mainly for file IO.
boofcv-ffmpeg	javacpp-presets their ffmepg wrapper is used for reading video files.
boofcv-jcodec	JCodec is a pure Java video reader/writer.
boofcv-openkinect	Used the Kinect RGB-D sensor with BoofCV.
boofcv-swing	Visualization using Java Swing
boofcv-WebcamCapture	A few functions that make WebcamCapture even easier to use.

Directories

Directory	Description
applications/	Helpful applications
data/	Directory containing optional data used by applets and examples.
demonstrations/	Demonstration code which typically lets experiment by changing parameters in real-time
examples/	Set of example code designed to be easy to read and understand.
integration/	Contains code which allows BoofCV to be easily integrated with 3rd party libraries. Primary for video input/output.
main/	Contains the source code for BoofCV

Building from Source

Building and installing BoofCV into your local Maven repository is easy[1] using the gradlew script:

cd boofcv
./gradlew assemble                # Creates auto generated files
./gradlew install                 # Installs it into the local maven repository 

If you wish to have jars instead, the following commands are provided.

./gradlew oneJarBin               # Builds a single jar with all of BoofCV in it
./gradlew createLibraryDirectory  # Puts all jars and dependencies into boofcv/library
./gradlew alljavadoc              # Combines all JavaDoc from all sub-porjects into a single set

[1] A couple of the integration submodules have a custom build process that can't be performed by Gradle. The script is smart enough to ignore modules and tell you that it is doing so if you haven't configured it yet.

IntelliJ

IntelliJ is the recommended IDE for use with BoofCV. With IntelliJ you can directly import the Gradle project.

1. File->Project From Existing Sources
2. Select your local "boofcv" directory
3. Confirm that you wish to import the Gradle project

Eclipse

The easiest way to import the project is to use Gradle to generate an Eclipse project.

cd boofcv
./gradlew eclipse

Then in Eclipse; 1) "import existing projects", 2) Select your BoofCV directory, 3) Click Finish. You can also install a Gradle plugin to Eclipse and import the project directory. That's left as an exercise for the reader.

Dependencies

Core BoofCV modules depends on the following libraries

• args4f
• EJML
• GeoRegression
• DDogleg
• DeepBoof

The following is required for unit tests

• JUnit

Code from the following libraries has been integrated into BoofCV

• General Purpose FFT by Takuya Ooura
  • Java port by Piotr Wendykier with modifications by Peter Abeles to recycle memory.

The optional sub-projects in integration also have several dependencies. See those sub-projects for a list of their dependencies.
