The import org.opencv.highgui cannot be resolved

问题:

I installed OpenCV (opencv-3.0.0-alpha) and it works proberly but I can't use that import

import org.opencv.core.*; import org.opencv.highgui.Highgui;  public class Main {      public static void main(String[] args) {  //      System.loadLibrary("opencv_java244"); //      Mat m = Highgui.imread("C:/Users/raj/Desktop/sa1.png", //              Highgui.CV_LOAD_IMAGE_COLOR); //      new LoadImage("C:/Users/raj/Desktop/dst1.jpg", m);     } } 

I get this error

The import org.opencv.highgui cannot be resolved 

How can I solve this?

回答1:

in opencv3.0, there is no more highgui module in java.

the functionality was split up into new videoio and imgcodecs (that's where you will find imread) modules.

since there is no gui available from java, - no need to have a highgui module anymore.

import org.opencv.core.*; import org.opencv.imgcodecs; // imread, imwrite, etc import org.opencv.videoio;   // VideoCapture 

回答2:

import org.opencv.imgcodecs.Imgcodecs; // imread, imwrite 

Not: org.opencv.imgcodecs;

Core.line, Core.Rectangle, Core.imread, Core.imwrite deprecated.

Use Imgcodecs.imread, Imgcodecs.imwrite, etc.
