adaptiveThreshold getting blank (full white) image
I want to apply adaptiveThreshold using open cv library to my bitmap image, but once i do with following code, it shows blank (full white) image, please help me to resolve it. following is code: Mat grayMat = imread(getImageUri(this, photo).getPath(), IMREAD_GRAYSCALE); Mat resultMat = new Mat(); Imgproc.adaptiveThreshold(grayMat, resultMat, 255, Imgproc.ADAPTIVE_THRESH_MEAN_C, Imgproc.THRESH_BINARY, 3, 40); Bitmap imgBitmap = Bitmap.createBitmap(resultMat.cols(), resultMat.rows(), Bitmap.Config.ARGB_8888);
Add following line after init. bitmap Utils.matToBitmap(resultMat, imgBitmap); and load imgBitmap to your ImageView, I hope this will solve your problem.
