Javacv: DnnSuperResImpl throws java.lang.UnsatisfiedLinkError

[cansik]

When I try to use DnnSuperResImpl with the current snapshot (1.5.3-SNAPSHOT) I immediately get the following error:

java.lang.UnsatisfiedLinkError: no jniopencv_dnn_superres in java.library.path

Here is an example code:

DnnSuperResImpl net = new DnnSuperResImpl();
net.readModel(model.toAbsolutePath().toString());
net.setModel("fsrcnn", 2);

I have even tried to load the library with:

Loader.load(opencv_java.class);
Loader.load(opencv_dnn_superres.class);

Is this library not bundled in the opencv preset build or am I using it the wrong way?

Works fine here on Linux. What's your platform?

It looks like there is a missing inheritance on opencv_quality here though:

Please let me know if it helps to call Loader.load(opencv_quality.class) before. Thanks!

Perfect, using Loader.load(opencv_quality.class) fixed it. I am working on MacOS (Catalina 10.15.3).

Fix included in just released version 1.5.3. Thanks for reporting and for testing!
