如何在java opencv中执行联合操作 [英] How to perform a union operation in java opencv

问题描述

我需要编写一个等效的 Java OpenCV 代码，因为这个 C ++ 代码

I need to write an equivalent Java OpenCV code as this C++ code

Mat1b mask1, mask2;
inRange(hsv, Scalar(0, 70, 50), Scalar(10, 255, 255), mask1);
inRange(hsv, Scalar(170, 70, 50), Scalar(180, 255, 255), mask2);

Mat1b mask = mask1 | mask2;

当我尝试使用 | 运算符时它会导致错误。

When i tried to use the | operator it leads to an error.

Mat mask1 = new Mat();
Mat mask2 = new Mat();
Core.inRange(hsv, new Scalar(0, 70, 50), new Scalar(10, 255, 255), mask1);
Core.inRange(hsv, new Scalar(170, 70, 50), new Scalar(180, 255, 255), mask2);

Mat hsvThres = mask1 | mask2;

错误：运营商|未定义参数类型org.opencv.core.Mat

推荐答案

联盟运营商， logic-或（|）用于OpenCV的两个矩阵：

Union operator, logic-or (|) for two matrix of the OpenCV:

C ++中的代码：

inRange(hsv, Scalar(0, 70, 50), Scalar(10, 255, 255), mask1);
inRange(hsv, Scalar(170, 70, 50), Scalar(180, 255, 255), mask2);

Mat mask = mask1 | mask2; 

Java代码：

Mat mask1 = new Mat();
Mat mask2 = new Mat();
Core.inRange(hsv, new Scalar(0, 70, 50), new Scalar(10, 255, 255), mask1);
Core.inRange(hsv, new Scalar(170, 70, 50), new Scalar(180, 255, 255), mask2);

Mat mask= new Mat();
Core.bitwise_or(mask1, mask2, mask);

Python中的代码：

Code in Python:

mask1 = cv2.inRange(hsv, (0, 70, 50), (10, 255, 255))
mask2 = cv2.inRange(hsv, (170, 70, 50), (180, 255, 255))
mask = cv2.bitwise_or(mask1, mask2)
