You could can get rid of these leaks by calling in your draw loop: ToPImage is called by all his opencv.image(), opencv.getBuffer*(), opencv.getMemory*(), so the leaks are huge mainly in a Processing draw loop.

Brew install opencv 3.1 code#

XavierвЂ™s original code in javacvPro-0.5 heavily uses the new PImage(), mainly in his method toPImage( ) (see line 337 of my code) (usually solved by calling g.removeCache() )

Brew install opencv 3.1 mods#

All my mods are marked with comments вЂ// YVESвЂ™Д«ut the main memory leak is indeed a bug in Processing itself, the well known PImage memory leak, see for instance In OpenCV.java (v0.5), i corrected various opencv memory management errors after studying the exemple code of Samuel Audet, the author of javacv. I am not a java guru and I hope, someone with more skills can help :-). There are only libopencv_core.dylib and a libopencv_core.2.4.dylib there. I donвЂ™t understand, why itвЂ™s searching in /opt/local/lib and why it seaches 2.3. When I try to start a sample from the javacvpro package, I receive the following error:Д®xception in thread вЂњAnimation ThreadвЂќ : /private/var/folders/dd/h2g1lb2d10b5vmd320lmscgr0000gn/T/libjniopencv_core3440981410919750257.dylib: Library not loaded: /opt/local/lib/libopencv_core.2.3.dylib Referenced from: /private/var/folders/dd/h2g1lb2d10b5vmd320lmscgr0000gn/T/libjniopencv_core3440981410919750257.dylib Reason: image not found вЂ“ installed javacvpro to the local libraries folder of processing.

Brew install opencv 3.1 mac#

Javacvpro on mac mountan lion / processing 2.0a8: The homepage of JavacvPro also has several videos (in French)В demonstrating different use examples, like this one for finger detection: I tested it on 2.0.a4, changing the вЂњLaunch programs inвЂќ option to 64-bit in the Preferences menu: However, on MacOSX the library only works with Java in 64-bit mode, which is supported in the latest alphas of Processing 2.0.

Brew install opencv 3.1 windows#

On Windows and Linux, I used the latest stable version of Processing, 1.5.1. Windows installation from pre-compiled binaries:.The installation process depends on the platform, fortunately there are several online resources to figure this out. The basic requirement to use JavacvPro is to install OpenCV 2.3.1.

Xavier has also included many examples in the library package that show how to use it various features. I did some testing of JavacvPro (version 0.3) on Windows, Mac and Linux, and the results are very promising as I was able to use the library on the three platforms. JavacvPro is based on the very solid JavaCV wrappers by Samuel Audet, which provide access to the latest version of OpenCV (2.3.1 at the time of writing this), and in fact also allows to use other computer vision frameworks like OpenKinect, and ARToolKit. This is a great contribution to the community, since it appears that the development of the original OpenCV library for Processing has stalled, without moving beyond OpenCV 1.0 support. Xavier Hinault recently released a new computer vision library for Processing, based on JavaCV and OpenCV 2: JavacvPro.
