Answer 1

Instead of struggling with manual installation of OpenCV libraries I suggest you use OpenCV Java library packaged by OpenPnP (https://github.com/openpnp/opencv) that includes all required DLL.

It does not require additonal steps except of adding it to your build automation tool configuration (Gradle in my case) and adding the following code to load the library:

 System.loadLibrary(org.opencv.core.Core.NATIVE_LIBRARY_NAME);
