如何使用Java中使用NDK的Andr​​oid？ [英] How to use Java with NDK Android?

问题描述

我假设使用OpenCV的code在这里： http://github.com/billmccord/OpenCV-Android#readme 是在Android上使用OpenCV的，与NDK的最佳方式。

I am assuming that using the OpenCV code here: http://github.com/billmccord/OpenCV-Android#readme is the best way to use OpenCV on Android, with the NDK.

我仍然坚持为我是如何从函数的C定义得到 对那些我宣布在OpenCV.java在我的Andr​​oid项目

I am still stuck as to how I get from the C definitions of functions to the ones I declare in OpenCV.java in my Android project

cvFindContours( void*  img,  CvMemStorage*  storage, 
                CvSeq**  firstContour, int  cntHeaderSize, 
                int  mode, 
                int  method, CvPoint offset ) --> findContours(int[] 
data, int w, int h) ) 

pciated任何帮助/指针AP $ P $，甚至从哪里开始摸不着头脑。 我现在想用 cvHoughCircles，cvHoughCircles（CvArr *图像， 无效* circle_storage，诠释法，双DP，双min_dist，双参数1 = 100，双参数2 = 300，INT min_radius = 0，INT max_radius = 0};

Any help/pointers appreciated, even where to start to figure this out. I currently want to use cvHoughCircles, cvHoughCircles(CvArr* image, void* circle_storage, int method, double dp, double min_dist, double param1 = 100, double param2 = 300, int min_radius = 0, int max_radius = 0};

我怎样写这在Java中使用NDK为Android？

推荐答案

请问您的应用程序所需要的C接口？ OpenCV的实际认为，德precated /做搭配，新的API是C ++。这个接口和样品校准应用程序的端口所在的位置： HTTP：//$c$c.google.com / P / Android的OpenCV的/

Does your app require the C interface? OpenCV actually considers it deprecated / done with, the new API is C++. A port of this interface and sample calibration app are here: http://code.google.com/p/android-opencv/

我花了，而在新的C ++获得出售，但我不得不承认，很高兴没有做cvReleaseMat（）和来回的IplImage和CvMat中的所有的时间。 OpenCV的2.1 DOC：<一href="http://opencv.willowgarage.com/documentation/cpp/index.html">http://opencv.willowgarage.com/documentation/cpp/index.html

It took me a while to get sold on the new C++, but I had to admit it was nice to not have to do cvReleaseMat() and go back and forth between IplImage and CvMat all the time. Opencv 2.1 doc: http://opencv.willowgarage.com/documentation/cpp/index.html
