OpenCV-两个二进制图像之间的交集 [英] OpenCV - Intersection between two binary images

问题描述

比方说，我有两个相同大小的二进制图像.如何找到两个二进制图像之间的交点?在两个白色(灰色-255)图像上，只有坐标(位置)相同的像素才会在输出图像(相交)上给出白色像素.

解决方案

您可以使用 cvAnd 或 cv: :bitwise_and 在两个图像上.仅当两个输入图像均为白色时，结果图像才会为白色.

这是应用 cv ::的结果: bitwise_and ， cv :: bitwise_or 并在二进制图像上 cv :: bitwise_xor : /p>

这是两个源图像:

这是应用 cv :: bitwise_and :

这是应用 cv :: bitwise_or :

这是应用 cv :: bitwise_xor :

Let's say I have two binary images of the same size. How do I find the intersection between the two binary images? Only pixels of the same coordinate (location) on the two images that are white (gray - 255) will give white pixels on the output image (intersection).

解决方案

You can use cvAnd or cv::bitwise_and on the two images. The resulting image will be white only where both the input images are white.

EDIT: Here are the results of applying cv::bitwise_and, cv::bitwise_or and cv::bitwise_xor on binary images:

These are the two source images:

Here is the result of applying cv::bitwise_and:

Here is the result of applying cv::bitwise_or:

Here is the result of applying cv::bitwise_xor:
