      public static final int COLOR_MIN = 0x00;

      public static final int COLOR_MAX = 0xFF;

      public static Bitmap applySnowEffect(Bitmap bitmap) {

            // get image size

            int width = bitmap.getWidth();

            int height = bitmap.getHeight();

            int[] pixels = new int[width * height];

            // get pixel array from source

            bitmap.getPixels(pixels, 0, width, 0, 0, width, height);

            // random object

            Random random = new Random();

            int R, G, B, index = 0, thresHold = 50;

            // iteration through pixels

            for (int y = 0; y < height; ++y) {

                  for (int x = 0; x < width; ++x) {

                        // get current index in 2D-matrix

                        index = y * width + x;

                        // get color

                        R = Color.red(pixels[index]);

                        G = Color.green(pixels[index]);

                        B = Color.blue(pixels[index]);

                        // generate threshold

                        thresHold = random.nextInt(COLOR_MAX);

                        if (R > thresHold && G > thresHold && B > thresHold) {

                              pixels[index] = Color.rgb(COLOR_MAX, COLOR_MAX, COLOR_MAX);

                        }

                  }

            }

            // output bitmap

            Bitmap bmOut = Bitmap

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

            bmOut.setPixels(pixels, 0, width, 0, 0, width, height);
