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

@berak Okay I' tried using float and i got 1.0 when i checked the value of a white pixel. Is that correct? also what doe

@berak is it still possible to get the pixel value of a mat and store that pixel value in an element of an array?

@berak changed it back to bytes and I check what value bytes[0] have and its -1. which is odd.

2018-11-13 10:23:54 -0500 marked best answer How can I improve the binarization of image in my sample app

I'a practicing in proprocessingiages in android studio and I want to improve the binarihiszation of images in my program, for example i have this image: image description

and my program is binarizing it to this:image description I would like to be able to maintain the horizontal lines(staff lines) for a horizontal line detection.

here is the piece of my code for the grayscale and binary: public void convGray(View view) { Mat Rgba = new Mat(); Mat grayMat = new Mat(); Mat imageBW = new Mat();

    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inDither=false;
    o.inSampleSize=4;

    int width =   imageBitmap.getWidth();
    int height = imageBitmap.getHeight();

    grayBitmap = Bitmap.createBitmap(width,height,Bitmap.Config.RGB_565);

    //bitmap to Mat

    Utils.bitmapToMat(imageBitmap,Rgba);
    Imgproc.cvtColor(Rgba,grayMat,Imgproc.COLOR_RGB2GRAY);
    Imgproc.threshold(grayMat,imageBW,100,255,Imgproc.THRESH_BINARY);
    Utils.matToBitmap(imageBW,grayBitmap);
    imageView.setImageBitmap(grayBitmap);
}
