Opencv importazione highgui in Android Studio sta mostrando error.Cannot risolvere (ho aggiunto la libreria rimane ancora l'errore)

Question

Ho il seguente codice che è per la segmentazione delle immagini utilizzando opencv grabcut. Sto usando opencv per la prima volta. Ho aggiunto la libreria opencv. Mentre altri hanno funzionato perfettamente, highgui mostra ancora non può risolvere il simbolo. Ho bisogno di aggiungere qualcos'altro. (Se mi potete aiutare con il codice di troppo, sarà un ulteriore aiuto) Ecco il codice: Edit: Ho inviato il codice aggiornato:

Answer 1

in opencv3.0, non v'è più moduli highgui in java.

la funzionalità è stata suddivisa in nuovi moduli videoio e imgcodecs (che è dove si trovano imread).

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

EDIT: Change img=Highgui.imread(pathtoimage); a img = Imgcodecs.imread(pathtoimage);

e Core.rectangle(img, tl, br, color); a Imgproc.rectangle(img, t1, br, color);

Vorrei anche suggerire passare attraverso OpenCV 3.0 modules per risolvere questi errori.

Answer 2

A seconda della struttura dei file, può invece essere:

import org.opencv.imgcodecs.Imgcodecs;
