erosion and dilation c++

To perform erosion and dilation in C++, you can use the OpenCV library. Here are the steps to achieve this:

1. Include the necessary header files:

#include <opencv2/opencv.hpp>

1. Read the input image:

cv::Mat inputImage = cv::imread("input.jpg", cv::IMREAD_GRAYSCALE);

1. Define the structuring element for erosion and dilation:

cv::Mat element = cv::getStructuringElement(cv::MORPH_RECT, cv::Size(3, 3));

1. Perform erosion on the input image:

cv::Mat erodedImage;
cv::erode(inputImage, erodedImage, element);

1. Perform dilation on the input image:

cv::Mat dilatedImage;
cv::dilate(inputImage, dilatedImage, element);

1. Display the results:

cv::imshow("Eroded Image", erodedImage);
cv::imshow("Dilated Image", dilatedImage);
cv::waitKey(0);

These steps will allow you to perform erosion and dilation on an image using C++ and the OpenCV library.
