javacv

I have a problem with JavaCV. I downloaded javaCV-bin and i added .jar file in my project in references libraries on ubuntu I could worked sample codes which locate in downloaded file But error is Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/libjniopencv_core3835922554849797701.so: libopencv_core.so.2.4: cannot open shared object file: No such file or directory at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1750) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1646) at java.lang.Runtime.load0(Runtime

Hi i am developing an app with Javacv. The app works fine until i proguard the build. After proguarding, the app crashes at the place of jni function call. -dontshrink -dontoptimize -dontpreverify -dontwarn android.support.** -keep class com.googlecode.javacv.** -dontwarn com.googlecode.javacv.** -keep class com.googlecode.javacpp.** -dontwarn com.googlecode.javacpp.** -keepclasseswithmembernames class * { native <methods>; } -keepattributes *Annotation* I can't find any answer that solves my problem. I am getting NoSuchMethodError. Anybody help me. I am using the latest version of Javacv

I had this piece of code to be converted into Java using OpenCV4Android. But their are no Java-Wrappers for matiterator in OpenCV4Android. void show_result(const cv::Mat& labels, const cv::Mat& centers, int height, int width) { std::cout << "===\n"; std::cout << "labels: " << labels.rows << " " << labels.cols << std::endl; std::cout << "centers: " << centers.rows << " " << centers.cols << std::endl; assert(labels.type() == CV_32SC1); assert(centers.type() == CV_32FC1); cv::Mat rgb_image(height, width, CV_8UC3); cv::MatIterator_<cv::Vec3b> rgb_first = rgb_image.begin<cv::Vec3b>(); cv:

I am trying to convert a C++ method from a previous answer I received using OpenCV to Java using OpenCV Java bindings C++ code: cv::Mat gray; cv::Mat element = cv::getStructuringElement(cv::MORPH_CROSS, cv::Size(2 * erosion_size + 1, 2 * erosion_size + 1), cv::Point(erosion_size, erosion_size) ); cv::erode(gray, gray, element); // Scan the image searching for points and store them in a vector std::vector<cv::Point> points; cv::Mat_<uchar>::iterator it = gray.begin<uchar>(); cv::Mat_<uchar>::iterator end = gray.end<uchar>(); for (; it != end; it++) { if (*it) points.push_back(it.pos()); } I can

So, I'm developing a custom video player for Android but I need to play more than the android supported video files (mp4, 3gp...), like wmv, avi, flv. At this time I do already convert any video type to .mp4 and I'm able to play them after recoding, but I have no idea how can I play those wmv , avi files without recoding them to mp4 video formats. Is there any way I can play any video on Android without recoding them? JavaCV + FFmpeg library already working, just don't know how to do that. By the way, heres the code that I'm using to recode videos: public static void convert(File file) {

I am working on school project and part of it should be about current situation about computer vision libraries for Android. I went to it with large enthusiasm because computer vision seems like fascinating subject but I have been searching for more then a week and I did not find much. I would like to be able to provide information about libraries themselves and about comparison between them. I will share what I found so far. OpenCV seems like the most advanced one and the most popular. provide the biggest number of functions it had problem with backward compatibility is fast(at least so I

While exporting in eclipse I choose "Package required libraries into generated jar". The jar file works only in my machine. However, when I test it on other machine it gives this Exception: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopencv_core in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1681) at java.lang.Runtime.loadLibrary0(Runtime.java:840) at java.lang.System.loadLibrary(System.java:1047) at com.googlecode.javacpp.Loader.loadLibrary(Loader.java:593) at com.googlecode.javacpp.Loader.load(Loader.java:489) at com.googlecode.javacpp.Loader
