hi,
i am not able to convert mat to bitmap in the below code. can any one tell me what wrong i am doing here.
here is the code :-
Mat rgb = new Mat ();
Mat rgb32f = new Mat();
Mat gry = new Mat ();
Mat imfilter = new Mat (height, width, CvType.CV_32F, new Scalar(4));
Mat res = new Mat();
Bitmap bmp = t1.copy(Bitmap.Config.ARGB_8888, true);
Utils.bitmapToMat(bmp, rgb);
rgb.convertTo(rgb32f, CvType.CV_32F);
Mat mu = new Mat();
Size ksize = new Size(5,5);
Imgproc.blur(rgb32f, mu,ksize);
Mat mu2 = new Mat();
Imgproc.blur(rgb32f.mul(rgb32f), mu2, ksize);
Mat sigma = new Mat();
Core.sqrt(mu2, sigma);
Core.normalize(sigma, gry, 0.0, 1.0, Core.NORM_MINMAX);
Bitmap scale = Bitmap.createBitmap(gry.cols(), gry.rows(), Bitmap.Config.ARGB_8888);
Utils.matToBitmap(gry, scale);
Error comes in the last line Utils.matToBitmap() function.
thanks....function.
here is logcat :-
