val destination = Mat()
        val matGray = Mat()
        Utils.bitmapToMat(bitmap, sourceMatImage)
        Imgproc.cvtColor(sourceMatImage, matGray, Imgproc.COLOR_BGR2GRAY)
        Imgproc.Laplacian(matGray, destination, 3)
        val median = MatOfDouble()
        val std = MatOfDouble()
        Core.meanStdDev(destination, median, std)
        return DecimalFormat("0.00").format(Math.pow(std.get(0, 0)[0], 2.0)).toDouble()
