OpenCV 2 in Processing   41 comments

Xavier Hinault recently released a new computer vision library for Processing, based on JavaCV and OpenCV 2: JavacvPro. 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. 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. 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. Xavier has also included many examples in the library package that show how to use it various features.

JNA on Android   3 comments

Samuel Audet, the author of JavaCV and other cool projects you can check out here, has been working on a port of JNA for Android. I haven’t tested it myself yet, but according to the wiki it has reached a functional state. This port would be very useful to simplify the access to native C libraries on the Android platform when coding with the Java SDK.

Installing gsvideo on Windows   5 comments

My first post about the gsvideo library for Processing was quite sparse, but now I have some additional info on how to install it on Windows. As I do more testing on other platforms, I’ll post further instructions about the installation process on OSX and Linux.

First of all, I realized that the version of Java (1.4.2) that comes with the standard Windows package of Processing is not compatible with the gsvideo library. This is probably because I compiled it with jdk 1.5, I will try to compile it with jdk 1.4 later. But for now, you have to use the “expert” version of processing, with jre 1.5 (or 1.6) installed separately.
