第一件事：我不是英語母語的人，所以我盡我所能。 我試圖使用JavaCV，但它不起作用。我得到的錯誤：JavaCV無法啓動
OpenJDK 64-Bit Server VM warning: You have loaded library /usr/lib/libtbb.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

我本教程安裝了OpenCV的： https://udallascs.wordpress.com/2014/03/30/adding-opencv-and-configuring-to-work-with-eclipse-and-java/
這裏是源代碼：
import com.googlecode.javacv.cpp.opencv_core.IplImage;
//import static com.googlecode.javacv.cpp.opencv_core.*;
//import static com.googlecode.javacv.cpp.opencv_imgproc.*;
//import static com.googlecode.javacv.cpp.opencv_highgui.*;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;
public class Main {
public static void main(String s[]) {
try {
BufferedImage bi = ImageIO.read(new File("/home/arjan/Desktop/HelloWorld.jpg"));
IplImage img = IplImage.createFrom(bi);
// cvShowImage("Hello-World",img);
// cvSmooth(img, img, CV_GAUSSIAN, 13);
// cvShowImage("Blur-Image",img);
// cvWaitKey();
// cvReleaseImage(img);
}catch (Exception ex) {ex.printStackTrace();}
}
}
我使用Arch Linux的，並與吃豆子 這裏還安裝了OpenCV的是我使用picture of jar files
我發現它有時會讀取我從他們不工作時得到的錯誤。通常他們幫助我解決我的問題。 –
