I use this line of code for binarizing images:

Imgproc.adaptiveThreshold(grayMat,imageBW,255,Imgproc.ADAPTIVE_THRESH_MEAN_C,Imgproc.THRESH_BINARY,5,4);

I tested it using this image. and the result is this image

the black part should be retained right? But in this case only the line that seperates the black and white remains black
