erreur: ne peut pas trouver le symbole CV_32FC3

Question

J'utilise HIPI pour faire un traitement d'images! Et à un moment donné, j'utilise la variable CV_32FC3 dans mon code quand je définis un opencv Mat.

Mat mat = new Mat(rows, cols, CV_32FC3); 

Malheureusement, je reçois une erreur disant que le symbole ne se trouve pas!

Ps:

• J'utilise bytedeco qui est intégré à IPAM pour faire du traitement
• images Dans le fichier build.gradle de IPAM, j'ai:

compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.3.2' 
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ' 
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ', classifier: 'macosx-x86_64' 
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ', classifier: 'linux-x86_64' 
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ', classifier: 'windows-x86_64' 

• Dans mon code, j'ai importé le opencv_core:

import org.bytedeco.javacpp.opencv_core.*; 
import org.bytedeco.javacpp.helper.opencv_core.*; 
import org.bytedeco.javacpp.presets.opencv_core.*; 

Quelqu'un peut-il me dire ce qui ne va pas? ou ce que j'ai oublié?

Le stacktrace d'erreur que je reçois est:

par le code il semble que vous utilisez Java (mais vous n'avez pas explicitement défini). Ainsi, dans Java, le type de Mat est stocké sous CvType classe donc vous devez créer la matrice comme:

Mat mat = new Mat(rows, cols, CvType.CV_32FC3);
