FPU Boost

I'm kind of thrilled right now. I just updated JavaCV to the latest version (2011-07-05) which includes OpenCV 2.3.0 and some precompiled code for Android devices with an FPU (armeabi-v7a). Just by replacing JavaCV I gained an enormously computation boost. Well, of course I knew that an FPU is better for heavy number crunching than… Continue reading FPU Boost

android-experimental + android-cmake (on Windows)

Just another desperate try to get something connected with OpenCV compiled under Windows. AndroidExperimental looked promising at the beginning. But of course everything just works on Linux without problems. The step where get_ndk_toolchain_linux.sh is referenced won't work on Windows and actually you don't need to do everything in there if you already have the NDK.… Continue reading android-experimental + android-cmake (on Windows)

javacv

JavaCV is a wrapper for a couple of libraries, including OpenCV. They also provide a pre-compiled OpenCV for Android. Looks promising. Will take a look at it. Wonder if this slows down the application somehow, because they are some more method calls because of the wrapper stuff I guess. But if it speeds up the… Continue reading javacv

OpenCV-Android

At github I found an optimized version of OpenCV for Android. Different to the original Android version this one can be compiled with the Android NDK (except with those creepy work-arounds described at opencv/AndroidTrunk). Unfortunately, the build process took like hours: because some variables needed by the linker aren't set on Windows (but obviously on… Continue reading OpenCV-Android
