Bitmap bmp = getIntent().getExtras().getParcelable(\"image_send\");

Answer 1

Mat tmp = new Mat (bmp.getWidth(), bmp.getHeight(), CvType.CV_8UC1);

OpenCV Mat constructor expects rows, cols pair instead of width, height as its arguments, invert them.

Try:

Mat tmp = new Mat (bmp.getHeight(), bmp.getWidth(), CvType.CV_8UC1);
