2014-12-09 13:46:29 -0600	marked best answer	Android rotate opencv native camera I am developing an android application which uses the opencv native camera using opencv2.4.2 sdk face detection samples. Is it possible to rotate the native camera to other angle when it open initially?
2014-12-09 13:44:46 -0600	marked best answer	Android opencv eye detection I am using android "opencv samples - face detection" to detect the face. It is working good. Now I want to include "eye detection" with "face detection". Is it possible? if yes can anyone give me some samples to detect the eye.
2014-12-09 13:44:45 -0600	marked best answer	Static Initialization on OpenCV Android Hi I am using OpenCV face-detection sample(OpenCV 2.4.2). I have changed the face-detection sample to OpenCV static initialization. I changed the below code in my FdActivity.java file. But I am not able to open native camera. when I call the "openCamera()" method it shows "Fatal error: can't open camera!" alert box. what seems to be the problem? `@Override public void onCreate(Bundle savedInstanceState) { Log.i(TAG, "onCreate"); super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Log.i(TAG, "Trying to load OpenCV library"); if (!OpenCVLoader.initDebug()) { Log.e(TAG, "Cannot connect to OpenCV Manager"); } else { mOpenCVCallBack.onManagerConnected(LoaderCallbackInterface.SUCCESS); } }` logcat: 10-12 09:44:01.604: I/Sample::Activity(676): Instantiated new class org.opencv.samples.fd.FdActivity 10-12 09:44:01.654: I/Sample::Activity(676): onCreate 10-12 09:44:01.704: I/Sample::Activity(676): Trying to load OpenCV library 10-12 09:44:01.704: D/OpenCV/StaticHelper(676): Trying to get library list 10-12 09:44:01.895: E/OpenCV/StaticHelper(676): OpenCV error: Cannot load info library for OpenCV 10-12 09:44:01.895: D/OpenCV/StaticHelper(676): Library list: "" 10-12 09:44:01.895: D/OpenCV/StaticHelper(676): First attempt to load libs 10-12 09:44:01.895: D/OpenCV/StaticHelper(676): Trying to init OpenCV libs 10-12 09:44:01.895: D/OpenCV/StaticHelper(676): Trying to load library opencv_java 10-12 09:44:01.895: D/dalvikvm(676): Trying to load lib /data/data/com.face.conf/lib/libopencv_java.so 0x411e3cc0 10-12 09:44:02.134: D/dalvikvm(676): Added shared lib /data/data/com.face.conf/lib/libopencv_java.so 0x411e3cc0 10-12 09:44:02.164: D/OpenCV/StaticHelper(676): OpenCV libs init was ok! 10-12 09:44:02.164: D/OpenCV/StaticHelper(676): First attempt to load libs is OK 10-12 09:44:02.164: I/Sample::Activity(676): OpenCV loaded successfully 10-12 09:44:02.164: I/Sample::Activity(676): OpenCV loaded successfully 10-12 09:44:02.174: D/dalvikvm(676): Trying to load lib /data/data/com.face.conf/lib/libdetection_based_tracker.so 0x411e3cc0 10-12 09:44:02.185: D/dalvikvm(676): Added shared lib /data/data/com.face.conf/lib/libdetection_based_tracker.so 0x411e3cc0 10-12 09:44:02.185: D/dalvikvm(676): No JNI_OnLoad found in /data/data/com.face.conf/lib/libdetection_based_tracker.so 0x411e3cc0, skipping init 10-12 09:44:02.394: I/Sample::SurfaceView(676): Instantiated new class org.opencv.samples.fd.FdView 10-12 09:44:02.654: I/Sample::FdView(676): Loaded cascade classifier from /data/data/com.face.conf/app_cascade/lbpcascade_frontalface.xml 10-12 09:44:02.654: D/dalvikvm(676): Trying to load lib /data/data/com.face.conf/lib/libdetection_based_tracker.so 0x411e3cc0 10-12 09:44:02.654: D/dalvikvm(676): Shared lib '/data/data/com.face.conf/lib/libdetection_based_tracker.so' already loaded in same CL 0x411e3cc0 10-12 09:44:02.924: I/Sample::SurfaceView(676): openCamera 10-12 09:44:02.924: I/Sample::SurfaceView(676): releaseCamera 10-12 09:44:02.934: D/CAMERA_ACTIVITY(676): Library name ...

2013-06-22 07:36:38 -0600	commented answer	Missing tbb lib for armeabi in 2.4.3 for Android? Thanks for the answer. Where can I enable the "WITH_TBB=ON" in OpenCV AndroidSDK. Can you give me the steps to build the android OpenCV SDK with TBB enabled?
2013-06-22 01:18:33 -0600	asked a question	TBB build with android OpeCV sample I am doing android "face-detection" application using OpenCV. For this I have downloaded the OpenCV-2.4.5-android-sdk and used the "face-detection" sample. The application is working good but the video streaming is too slow. So I want to speed up the application using TBB build. I found that "Enabled multi-threading support with TBB" from http://code.opencv.org/projects/opencv/wiki/Android_Release_Notes#240 and also "The good news is that Intel TBB had been build for Android and tested with some OpenCV samples" from the following link. http://code.opencv.org/projects/opencv/wiki/Android_Release_Notes#231-beta1 But I don't know how to build the TBB with "face-detection" sample. Can someone give me the steps to build TBB with the android OpenCV sample? *Updated:* *Finally I found that "OpenCV-2.4.5-android-sdk" basically comes with TBB.* *(i.e)libtbb.a available in "\OpenCV-2.4.5-android-sdk\sdk\native\3rdparty\libs\armeabi-v7a" folder* *and tbb-("OPENCV_3RDPARTY_COMPONENTS:=tbb libjpeg libpng libtiff libjasper IlmImf") is included in "\OpenCV-2.4.5-android-sdk\sdk\native\jni\OpenCV.mk" file* *But I don't know exactly this is correct. Please can you tell me is this correct or not?*

2013-06-21 10:05:45 -0600	edited question	OpenCL and GPU with Android OpenCV SDK I have found that from the following links, The OpenCL and GPU is available in OpenCV. http://docs.opencv.org/2.4.5/modules/ocl/doc/ocl.html. http://docs.opencv.org/2.4.5/modules/gpu/doc/gpu.html Is it possible to obtain OpenCV Android SDK with OpenCL and GPU.
