JavaCV ====== [](https://gitter.im/bytedeco/javacv?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://maven-badges.herokuapp.com/maven-central/org.bytedeco/javacv) [](https://travis-ci.org/bytedeco/javacv) Introduction ------------ JavaCV uses wrappers from the [JavaCPP Presets](https://github.com/bytedeco/javacpp-presets) of commonly used libraries by researchers in the field of computer vision ([OpenCV](http://opencv.org/), [FFmpeg](http://ffmpeg.org/), [libdc1394](http://damien.douxchamps.net/ieee1394/libdc1394/), [PGR FlyCapture](http://www.ptgrey.com/products/pgrflycapture/), [OpenKinect](http://openkinect.org/), [librealsense](https://github.com/IntelRealSense/librealsense), [CL PS3 Eye Driver](https://codelaboratories.com/downloads/), [videoInput](http://muonics.net/school/spring05/videoInput/), [ARToolKitPlus](http://studierstube.icg.tugraz.at/handheld_ar/artoolkitplus.php), and [flandmark](http://cmp.felk.cvut.cz/~uricamic/flandmark/)), and provides utility classes to make their functionality easier to use on the Java platform, including Android. JavaCV also comes with hardware accelerated full-screen image display (`CanvasFrame` and `GLCanvasFrame`), easy-to-use methods to execute code in parallel on multiple cores (`Parallel`), user-friendly geometric and color calibration of cameras and projectors (`GeometricCalibrator`, `ProCamGeometricCalibrator`, `ProCamColorCalibrator`), detection and matching of feature points (`ObjectFinder`), a set of classes that implement direct image alignment of projector-camera systems (mainly `GNImageAligner`, `ProjectiveTransformer`, `ProjectiveColorTransformer`, `ProCamTransformer`, and `ReflectanceInitializer`), a blob analysis package (`Blobs`), as well as miscellaneous functionality in the `JavaCV` class. Some of these classes also have an OpenCL and OpenGL counterpart, their names ending with `CL` or starting with `GL`, i.e.: `JavaCVCL`, `GLCanvasFrame`, etc. To learn how to use the API, since documentation currently lacks, please refer to the [Sample Usage](#sample-usage) section below as well as the [sample programs](https://github.com/bytedeco/javacv/tree/master/samples/), including two for Android (`FacePreview.java` and `RecordActivity.java`), also found in the `samples` directory. You may also find it useful to refer to the source code of [ProCamCalib](https://github.com/bytedeco/procamcalib) and [ProCamTracker](https://github.com/bytedeco/procamtracker) as well as [examples ported from OpenCV2 Cookbook](https://github.com/bytedeco/javacv-examples/) and the associated [wiki pages](https://github.com/bytedeco/javacv-examples/blob/master/OpenCV2_Cookbook). Please keep me informed of any updates or fixes you make to the code so that I may integrate them into the next release. Thank you! And feel free to ask questions on [the mailing list](http://groups.google.com/group/javacv) if you encounter any problems with the software! I am sure it is far from perfect... Downloads --------- To install manually the JAR files, obtain the following archives and follow the instructions in the [Manual Installation](#manual-installation) section below. * JavaCV 1.3.3 binary archive [javacv-platform-1.3.3-bin.zip](http://search.maven.org/remotecontent?filepath=org/bytedeco/javacv-platform/1.3.3/javacv-platform-1.3.3-bin.zip) (212 MB) * JavaCV 1.3.3 source archive [javacv-platform-1.3.3-src.zip](http://search.maven.org/remotecontent?filepath=org/bytedeco/javacv-platform/1.3.3/javacv-platform-1.3.3-src.zip) (456 KB) The binary archive contains builds for Android, Linux, Mac OS X, and Windows. The JAR files for specific child modules or platforms can also be obtained individually from the [Maven Central Repository](http://search.maven.org/#search|ga|1|bytedeco). We can also have everything downloaded and installed automatically with: * Maven (inside the `pom.xml` file) ```xml <dependency> <groupId>org.bytedeco</groupId> <artifactId>javacv-platform</artifactId> <version>1.3.3</version> </dependency> ``` * Gradle (inside the `build.gradle` file) ```groovy dependencies { compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.3.3' } ``` * sbt (inside the `build.sbt` file) ```scala libraryDependencies += "org.bytedeco" % "javacv-platform" % "1.3.3" ``` This downloads binaries for all platforms, but to get binaries for only one platform we can set the `javacpp.platform` system property (via the `-D` command line option) to something like `android-arm`, `linux-x86_64`, `macosx-x86_64`, `windows-x86_64`, etc. Please refer to the [README.md file of the JavaCPP Presets](https://github.com/bytedeco/javacpp-presets#downloads) for details. Another option available for Scala users is [sbt-javacv](https://github.com/bytedeco/sbt-javacv). Required Software ----------------- To use JavaCV, you will first need to download and install the following software: * An implementation of Java SE 7 or newer: * OpenJDK http://openjdk.java.net/install/ or * Sun JDK http://www.oracle.com/technetwork/java/javase/downloads/ or * IBM JDK http://www.ibm.com/developerworks/java/jdk/ Further, although not always required, some functionality of JavaCV also relies on: * CL Eye Platform SDK (Windows only) http://codelaboratories.com/downloads/ * Android SDK API 14 or newer http://developer.android.com/sdk/ * JOCL and JOGL from JogAmp http://jogamp.org/ Finally, please make sure everything has the same bitness: **32-bit and 64-bit modules do not mix under any circumstances**. Manual Installation ------------------- Simply put all the desired JAR files (`opencv*.jar`, `ffmpeg*.jar`, etc.), in addition to `javacpp.jar` and `javacv.jar`, somewhere in your class path. Here are some more specific instructions for common cases: NetBeans (Java SE 7 or newer): 1. In the Projects window, right-click the Libraries node of your project, and select "Add JAR/Folder...". 2. Locate the JAR files, select them, and click OK. Eclipse (Java SE 7 or newer): 1. Navigate to Project > Properties > Java Build Path > Libraries and click "Add External JARs...". 2. Locate the JAR files, select them, and click OK. IntelliJ IDEA (Android 4.0 or newer): 1. Follow the instructions on this page: http://developer.android.com/training/basics/firstapp/ 2. Copy all the JAR files into the `app/libs` subdirectory. 3. Navigate to File > Project Structure > app > Dependencies, click `+`, and select "2 File dependency". 4. Select all the JAR files from the `libs` subdirectory. After that, the wrapper classes for OpenCV and FFmpeg, for example, can automatically access all of their C/C++ APIs: * [OpenCV documentation](http://docs.opencv.org/master/) * [FFmpeg documentation](http://ffmpeg.org/doxygen/trunk/) Sample Usage ------------ The class definitions are basically ports to Java of the original header files in C/C++, and I deliberately decided to keep as much of the original syntax as possible. For example, here is a method that tries to load an image file, smooth it, and save it back to disk: ```java import static org.bytedeco.javacpp.opencv_core.*; import static org.bytedeco.javacpp.opencv_imgproc.*; import static org.bytedeco.javacpp.opencv_imgcodecs.*; public class Smoother { public static void smooth(String filename) { IplImage image = cvLoadImage(filename); if (image != null) { cvSmooth(image, image); cvSaveImage(filename, image); cvReleaseImage(image); } } } ``` JavaCV also comes with helper classes
