我正在使用opencvandroidsdk开发一个用于颜色检测的android项目。我已经能够从图像中分离出绿色和棕色的遮罩，但是我想要图像中绿色和棕色的百分比。我不知道该怎么做。

oImage = imread(pathOfFile);
hsvImage = new Mat();
color_range1 = new Mat();
color_range2 = new Mat();

Imgproc.cvtColor(oImage, hsvImage, Imgproc.COLOR_BGR2HSV);
Core.inRange(hsvImage, new Scalar(25,52,72), new Scalar(102,255,255), color_range1); // Green
Core.inRange(hsvImage, new Scalar(10, 100, 20), new Scalar(20, 255, 200), color_range2); // Brown

// I have the Green and Brown mask in color_range1 and color_range2 respectively.
// Now what

color_range1.release();
color_range2.release();
hsvImage.release();
oImage.release();

我有一个可行的解决方案的python实现，但不知道如何将其转换为java。

img = cv2.imread("__FILE_PATH__")
    grid_HSV = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)

    lower_green = np.array([25,52,72])
    upper_green = np.array([102,255,255])

    lower_brown = np.array([10, 100, 20])
    upper_brown = np.array([20, 255, 200])

    mask= cv2.inRange(grid_HSV, lower_green, upper_green)
    brown_mask= cv2.inRange(grid_HSV, lower_brown, upper_brown)

    Green Percent - round(((mask>0).mean())*100,3)
    Brown Percent - round(((brown_mask>0).mean())*100,3)
