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 boofcvgit submodule update --init --recursive

To run BoofCV you need Java 11 or newer and any free version will work, e.g.Zulu. To build BoofCV, just let the Gradle script handle everything. It will automatically download what it needs and ignore your local JDK if it's not compatible.

cd boofcvgit clean -fd main# Removes stale autogenerated code./gradlew autogenerate./gradlew examplesJarjava -jar examples/examples.jar./gradlew demonstrationsJarjava -jar demonstrations/demonstrations.jar

All the code for examples and demonstrations is in boofcv/examples and boofcv/demonstrations. Example code is intended easy to understand, so look there first.

BoofCV is onMaven Central and can be easily added to your favorite build systems; Maven, Gradle, ... etc. It's divided up into many modules, but most people will just need 'boofcv-core'. Additional modules are listed below for GUI and IO components. To include it in a Gradle project add the following to your dependencies:

For Gradle projects:

dependencies {    api(group: 'org.boofcv', name: 'boofcv-core', version: '1.2.4')}

Here are a list of the most commonly used modules and what they are for:

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

cd boofcvgit clean -fd main# Removes stale autogenerated code./gradlew autogenerate# Creates auto generated files./gradlew publishToMavenLocal# 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-projects 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 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

Similar to IntelliJ, you can now import Gradle projects like BoofCV using the Buildship tooling.Instructions

Core BoofCV modules depends on the following libraries

• args4j
• 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.
