I am using OpenCV for adaptiveThreshold. My code for image processing using OpenCV is like this:

imageMat=new Mat();
Utils.bitmapToMat(bmp, imag         


        

Answer 1

Maybe you are forgetting to include the openCV library.

Include

static { 
     System.loadLibrary("opencv_java");
}

for OpenCV version 3 you should instead add:

static { 
     System.loadLibrary("opencv_java3");
}

Good Luck :)
