Fehler: Symbol kann nicht gefunden werden CV_32FC3

Question

Ich verwende HIPI, um einige Bilder zu verarbeiten! Und an einem Punkt verwende ich die Variable CV_32FC3 in meinem Code, wenn ich eine opencv Mat definieren.

Leider bekomme ich eine Fehlermeldung, dass das Symbol nicht gefunden wird!

Ps:

• Ich benutze bytedeco, die integriert ist, um HiPi Bilder zu tun
Verarbeitung
• In der build.gradle Datei von KVPI, ich habe:

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' 

• In meinem Code habe ich den opencv_core importiert:

Kann mir jemand sagen, was los ist? oder was habe ich vergessen?

Der Fehler Stacktrace, die ich erhalte ist:

durch den Code es scheint, dass Sie Java verwenden (jedoch nicht explizit definiert haben). So in Java wird die Art von Mat unter CvType Klasse gespeichert, so dass Sie die Matrix erstellen müssen wie:

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