2013-11-05 08:39:54 -0600 | commented question | face recognition on android Can you give more details? get method needs some parameter for model, do you mean "model.obj", I tried to return the address of "model.obj", but I get wrong address when returned to Java, and can't rebuild the Face Recognizer when I call next time. By the way, there seems to be some problems in JNI when passing jlong, can you help me? Thank you. |
2013-11-04 10:33:03 -0600 | asked a question | face recognition on android Hi all! After two days' coding, I successfully make face recognition algorithm of opencv run on Android, and it is awesome! But, I still have some problems which seem to be my bottleneck. Image frames captured by the Java Camera(using OpenCV for Android) is Mat, and, as the same as the samples, I pass the nativeObjAddr(a long value) of the Mat to the native layer, it works well. Since I don't want to train the images every time a image frame comes, so I saved the model to a file in initialize method, and load it when recognizing. But my problem is, is there any better way for me? Like the way dealing with image frames which passes the address of the Mat, can I save the address of the model, and rebuild it when recognizing? Actually, I tried many many times, but all failed. Anyone can help? Any advice will be appreciated. some codes of current native layer likes this: |
