How can I get started with OpenCV in C++?

To get started with OpenCV in C++, first install OpenCV on your system. You can find installation instructions on the official OpenCV website.

What are the basic functions I should know?

Some basic functions include cv::imread for reading images, cv::imshow for displaying images, and cv::cvtColor for color space conversion.

Can you show me a simple example of loading and displaying an image?

Sure! Here's a simple example:

#include <opencv2/opencv.hpp>

int main() {
    cv::Mat image = cv::imread("path/to/image.jpg");
    cv::imshow("Display Window", image);
    cv::waitKey(0);
    return 0;
}

What if I want to process the image?

You can apply various image processing techniques like blurring, edge detection, and transformations using functions like cv::GaussianBlur and cv::Canny.
