On my DROID phone, it usually takes 4 seconds to extract features from one image. Notice: if you select a large image in the gallery, the program may crash due to limited memory. Press the menu button again to select it from your gallery and features are automatically extracted. The down-sampled image is saved in your gallery. Press the menu button to select your camera to capture an image. ![]() tSourceImage(pixels, width, height) īyte imageData = opencv.getSourceImage() īitmap = codeByteArray(imageData, 0, Public native boolean setSourceImage(int pixels, int width, int height) Īnd here is the code how we use these two functions:īitmap bitmap = codeFile(mCurrentImagePath) īitmap.getPixels(pixels, 0, width, 0, 0, width, height) The interface between JVM and OpenCV is pretty simple: setSourceImage and getSourceImage. After OpenCV finishes extracting SURF features, it send the processed image back to JVM. ![]() The general idea is that I use the intent to start the camera or gallery activities to get the image and send this image to OpenCV. They are a little bit long so I do not want to paste the source code here. I have three java files which can be downloaded here. It will generate libopencv.so in the libs/armeabi folder. Run “$NDK/ndk-build” from your project directory. In the root directory of the project, create a new folder called jni and extract all files in android_ to this folder. The laterst version of OpenCV uses lots of STL functions.Ĭreate a new Android project in eclipse. Currently (NDK r4) only C is fully supported, so I can only use OpenCV 1.1 under Android. This tool is used to cross compile OpenCV source code to Android. Details can be found hereĭownload Androdi NDK. Details can be found hereĭownload eclipse and install the ADT plugin. This tutorial is tested under Ubuntu 10.04 + Android SDKr07 + Android NDKr4b.ĭownload and install Android SDK. I believe most of us need that library so can someone do anything about it pls. I got all the materials need to wrap openCV library but not the knowledge how to do it. I'v try to wrap a openCV library for b4a but without successes.My knowledge with java is NONE.
